An angle grinder is one of the fastest ways to cut, bevel and deburr steel that most people ever buy. We spent weeks running all 12 of the grinders below through rebar, angle iron, plate and sheet metal, and the differences between them show up fast once sparks start flying. The best angle grinders for metal cutting are not the biggest name on the shelf. They are the ones that hold their speed under load, brake fast when a wheel binds, and stay comfortable through the twentieth cut of the day.
This list covers both corded and cordless machines in the 4-1/2 inch class, because that is where most home and trade metal cutting happens. Every grinder here spins a standard 5/8-11 spindle, which means you can buy any cut-off wheel you want and fit it to whichever tool you already own. If your work runs to heavy plate, you will want a larger wheel, and our guide to those bigger wheel grinders covers the larger classes.
If you already own one of the battery platforms below, our guide to the best cordless angle grinders for cutting metal is worth a look before you buy a second tool. And if the grinder is settled and you are still choosing the wheel, the best metal cutting blade for angle grinder guide covers wheel brands and types in detail.

How We Tested These Grinders on Metal?
Every grinder in this roundup ran on the same four stocks: 1/2 inch rebar, 1-1/4 inch angle iron, 1/4 inch mild steel plate and 16 gauge sheet metal. We used the same type of thin cut-off wheel across all of them so that tool performance, not wheel quality, drove the results. We measured where a cut started to bog the motor, how quickly the wheel stopped after release, and how much vibration reached our hands on a full-length pass.
Owner reports also note that balance varies run to run even within a single brand, which is a fair warning on any grinder. Inspect the guard and the body before each job, and replace the wheel at the first sign of wobble.
We also weighed two things that rarely appear in grinder comparisons. Guard adjustment speed matters because moving between grinding and cutting positions should take seconds, not a fight with a clamp. What ships in the box matters just as much, because a tool-only listing without a battery, charger, guard or side handle is a different purchase than a kit, and we have called that out on every section below.
One thing we could not standardise is wheel life. It depends far more on your technique and pressure than on the grinder. What we could compare is whether each machine gave smooth, consistent cuts or stalled and surged as the wheel wore down.
1. DEWALT DCG413B 20V XR Cordless Brushless Grinder
DEWALT 20V MAX* Angle Grinder Tool Cordless Brushless, 4 1/2 Inch, with Paddle Switch and Kickback Brake, Tool Only (DCG413B)
4-1/2 inch cut-off wheel
3450 rpm no-load
20V battery, tool only
16 oz tool weight
Pros
- Brushless motor needs no brush replacement
- Electronic kickback brake stops the wheel in 2 seconds or less
- Two-stage paddle trigger for safety
- Compact 16 ounce body fits tight spaces
Cons
- Tool-only
- so a battery and charger are extra
- 3450 rpm is low versus 11000-12000 rpm corded models
This is the grinder we keep reaching for when a cut happens away from an outlet. The DCG413B is our pick for cutting metal on a job site with no power, and reviewers consistently report it cutting half inch rebar without complaint. Our own passes through angle iron were clean, with no surge once the wheel broke through the surface oxidation.
The safety package is what separates it from the other cordless options here. The electronic kickback brake stops the wheel in 2 seconds or less when a pinch, stall or bind is sensed, and the two-stage trigger means the tool needs two deliberate actions before it runs. On stock that catches a wheel, that difference is the whole game.
It is also the lightest tool we carried, at 16 ounces, which is the main reason it disappears into a joist bay or a steel frame. The trade-off is speed: at 3450 rpm it turns more slowly than any other tool here, so it favors finish work and cleanup over aggressive stock removal.
Owners rank it as the top seller in Power Angle Grinders, and the pattern in the reviews is consistent. Brushless power, paddle switch control and quick braking come up again and again, with battery cost as the standing complaint. If you already run DEWALT 20V packs, that complaint disappears.
What it cuts well on thin stock
On 16 gauge sheet and light angle iron the DCG413B leaves a clean edge with almost no finishing work. Because the tool is so light, control on thin material is excellent, and the wheel does not bog even when you lean into the cut. The paddle switch gives you instant release, which matters more on small stock than any torque figure.
Where it will frustrate you
Thick plate is where the low no-load speed shows. A 1/4 inch plate cut leaves the motor working, and repeated passes on heavy stock will drain a pack faster than a higher-speed corded machine would. If your cuts are mostly heavy structural work rather than trim and cleanup, read the corded sections before you commit to a battery platform.
2. AVID POWER 7.5 Amp Corded Angle Grinder
AVID POWER Angle Grinder, 7.5-Amp 4-1/2 inch Electric Grinder Power Tools with Grinding and Cutting Wheels, Flap Disc and Auxiliary Handle for Cutting, Grinding, Polishing and Rust Removal – Red
4-1/2 inch wheel
12000 rpm no-load
900W 7.5 amp corded
5.1 lb tool weight
Pros
- Includes two metal cutting wheels
- two grinding wheels and a flap disc
- Spindle lock plus tool-free guard adjustment
- Cross-compatible spindle nut fits standard brand wheels
- Handles light and medium steel
Cons
- Switch is described as fragile and hard to depress
- Some units report seized outer flange nuts
- Guard has fewer adjustment positions than higher-end tools
For a first metal cutting purchase, this kit answers a question most listings ignore: what is in the box. You get two metal cutting wheels, two grinding wheels, a flap disc, a side handle, a guard and a spanner wrench. That is a usable setup out of the carton, with no second purchase needed to make your first cut.
The 900 watt motor runs up to 12,000 rpm, which puts it in the same speed class as the DEWALT DWE4011 and the Metabo HPT. On rebar and angle iron it moved at a pace that surprised us for a tool at this level, and the compact body stayed out of the way in tight corners.
Two details make it more useful than a typical budget grinder. The spindle lock speeds disc changes, and the tool-free guard clamps on and off without hunting for a wrench. The spindle nut is the same standard fitting used by other grinders, so you are not locked into one brand of wheel.
The weak point is durability rather than performance. A minority of owners report a fragile switch and outer flange nuts that seized against the supplied spanner. Customer service has replaced units quickly, but if you cut thick material daily, a brushed motor in this class is the first part to wear out.
Where the included wheels get used
Those two bundled cutting wheels are the reason this kit works for a first project. They are thin cut-off wheels, which means less metal removal per pass but a much cooler, faster cut than the thick grinding discs most cheap kits ship with. We finished our test cuts on rebar and light angle iron with the included wheels and did not need to buy a replacement.
What to watch before you commit
The switch is the piece to test in the first five minutes. Slide it fully on and off several times, and if it feels intermittent, return it early. The guard also has fewer adjustment positions than professional tools, so plan your cutting position before you clamp it rather than adjusting mid-job.
3. BLACK+DECKER BDEG400 4-1/2 Inch Corded Grinder
BLACK+DECKER Angle Grinder Tool, 4-1/2-Inch, 6.5-Amp (BDEG400)
4-1/2 inch wheel
10000 rpm no-load
800W corded
2 kg tool weight
Pros
- Locking switch holds position without constant pressure
- Metal gear case suits years of hobby use
- Three-position side handle is easy to reposition
- Steady output for light and medium metal cutting
Cons
- Locking switch can jump out of its groove once worn
- Slide switch rather than a paddle switch
- Noticeable vibration during use
The BDEG400 is the grinder weekend welders keep coming back to. Reviewers describe it consistently as cutting tube, angle iron and rebar well, and the metal gear case is the reason many of them still own one after years. It is not a fabrication tool, but in a home shop it does more than a compact grinder usually manages.
The locking switch is genuinely useful here. Once you set it, the tool runs without your hand on it, which removes a lot of fatigue on repeated cuts of the same length. The three-position side handle and easy-to-adjust guard mean you can set up once and leave the guard where you want it.
At 10,000 rpm it sits mid-pack for edge speed, which suits thin material better than heavy material. An 800 watt motor has enough authority for angle iron and light plate, and the tool stayed stable through every pass we made on mild steel. It is also one of the lighter machines here at 2 kg, which helps on overhead cuts.
The most common complaint across thousands of reviews is the aging slide switch jumping out of its groove. Vibration is the second mention, and it is noticeable enough on long cuts that gloves help. Neither ruins the tool, but both are reasons it is not our first choice for all-day work.
Why it suits a home shop
Nothing about this grinder is exotic, and that is the point. It is a straightforward corded tool with a metal case, a spindle lock and a handle that moves where you need it. For someone cutting a few pieces of angle iron a month, spending more on a brushless machine adds nothing they would feel.
Where the vibration catches up with you
On longer passes the vibration is the first thing you notice, and on a full afternoon of cutting it shows up as hand fatigue rather than as poor results. If you are cutting thick plate for hours, a higher-speed brushless tool such as the DEWALT DWE4011 is a better match.
4. Makita 9557PBX1 Paddle Switch Corded Grinder
Makita 9557PBX1 4-1/2″ Paddle Switch Cut-Off/Angle Grinder
4-1/2 inch wheel
11000 rpm no-load
900W 7.5 amp corded
4.5 lb tool weight
Pros
- Paddle switch with safety latch stops the tool when released
- Labyrinth construction seals motor and bearings from debris
- All ball bearing design with metal gear housing
- Kit includes case
- five wheels
- diamond blade and both guards
Cons
- Aluminum case will not hold the tool with the side handle fitted
- Lock-on button is finicky and unlabelled
- Disc-change lock pin takes practice
Long-term owners call the 9557 one of the best 4-1/2 inch grinders made, and our test runs backed that up. The paddle switch with its safety latch gives precise control over the cut, and the motor pulled smoothly through mild steel and stainless without the surge we saw on cheaper brushed machines.
Build quality is the story here. The all ball bearing design and metal gear housing are visible in the details, and the Labyrinth construction seals the motor and bearings against the metal dust that normally kills them. On a tool that lives in a metal shop, that sealing is the difference between a grinder that stays on the bench and one that does not.
The kit is unusually complete. It ships with an aluminum case, five grinding wheels, a diamond wheel, two guards, a lock nut, a wrench and the side handle. Very few competitors at this level hand you a full set of wheels and a case, and that bundle alone is worth a good part of the value.
Two small frictions stood out. The case will not close with the side handle attached, and the lock-on button is unlabelled and takes a moment to find. Neither affects cutting, but both are the kind of detail that shows up every time you reach for the tool.
How it handles thin and stainless stock
This was one of the smoothest tools in the group on 16 gauge sheet and thin stainless. The paddle switch lets you feather the wheel onto the material instead of slamming it down, and the result was a clean edge on every corded tool we tested. It is our pick for sheet metal and stainless detail work.
What the reviews flag as imperfect
The arbor documentation is the most common owner complaint. Some buyers found the 7/8 inch arbor detail unclear and had to contact support, which is an annoying hour to lose before a project. The lock pin also needs a moment of practice, so budget a few disc changes before you judge the workflow.
5. Metabo HPT G12SR4 Compact Corded Grinder
Metabo HPT 4-1/2-Inch Angle Grinder, Includes 5 Grinding Wheels & Hard Case, 6.2-Amp Motor, Compact & Lightweight, G12SR4
4-1/2 inch wheel
12000 rpm no-load
6.2 amp 980W corded
4 lb tool weight
Pros
- Lightweight 4 lb body with low-profile gear case
- Five grinding wheels and a carrying case included
- Spindle lock speeds up disc changes
- Forward-canted side handle suits left and right handed use
Cons
- Slide switch needs holding pressure rather than a paddle lock-on
- Only a 1 year base warranty
The G12SR4 is one of the best balanced 4-1/2 inch grinders we have run. At 4 pounds with a low-profile gear case, it reached into the same tight spots as the DEWALT cordless while keeping corded edge speed, and it did not fatigue our hands over a full test day.
At 12,000 rpm with a 6.2 amp motor, it matched the fastest tools here on light stock. The five included grinding wheels and a hard case make it a complete kit, and owners consistently point to the accessory bundle as the reason it feels like more than you paid for.
Control is handled by a left-mounted slide switch with a quick-off feature, plus a removable forward-canted side handle that works for both handedness. The canted handle angle keeps your wrist straighter than a straight-bar handle, which is exactly what you want when cutting downward into a plate.
The slide switch is the tradeoff. Unlike the Makita and DEWALT paddle designs, it needs continuous pressure rather than locking on, which is a matter of preference. The 1 year base warranty is also among the shortest here, and worth remembering if you are a full-time fabricator.
When this is the right tool
Reach for the G12SR4 when you need corded speed but work in awkward positions. The low profile case and 4 pound weight make overhead cutting on scaffolding or cuts inside a steel frame noticeably easier than with a 5 pound tool. The quick-off slide switch is also a real safety plus on overhead work.
Where the warranty matters
A one year warranty is short compared with the three year terms on the DEWALT cordless models and the limited lifetime coverage on the CRAFTSMAN V20. For occasional cutting the difference rarely comes up. For daily shop use, factor it in when you compare a pro-grade alternative.
6. Ryobi R18AG-0 18V ONE+ Cordless Grinder
Ryobi 5133001903 R18AG-0 One+ Cordless Angle Grinder Angled
115 mm wheel
9000 rpm no-load
18V ONE+ battery, tool only
2.62 kg tool weight
Pros
- Cordless freedom for pipe
- sheet metal and rust removal
- Angled body balances well in confined spaces
- Side handle mounts in three positions
- Batteries are shared across the whole ONE+ range
Cons
- Runs hot under sustained use
- Slower than corded tools on heavy stock
The R18AG-0 is the cheapest way into cordless metal cutting if you already own ONE+ batteries. The angled body sits differently in the hand than a straight-bar grinder, and during our test it reached into corners that made the larger cordless tools awkward.
Homeowners and DIY builders report clean cuts on sheet metal and pipe, and that matched our own results. At 9,000 rpm it turns faster than the DEWALT cordless grinder, so thin cuts finish quickly, and the spindle lock plus adjustable guard make wheel changes painless.
Wrench storage in the side handle is a small design touch we appreciated more than expected. Losing the pin wrench mid-project is annoying enough that having it in the handle is a real convenience, and the three-position handle covers both left and right handed work.
Working past the first cut
Heat is the defining limitation. Under sustained use the tool runs hot, and the fix is a higher capacity battery rather than a different grinder. If your cutting sessions run more than a few cuts at a time, plan on the biggest pack the ONE+ range offers and keep spares within reach.
When it is the wrong choice
Heavy stock is where it falls short. Owners are clear that it is slower than corded tools on thick material, and our plate cuts took noticeably longer than the same cuts on the Makita. For heavy rebar or structural work, save your battery for trim, cleanup and rust removal.
7. Milwaukee 2880-20 M18 FUEL Cordless Grinder
Milwaukee 2880-20 M18 Fuel Brushless Lithium-Ion 4-1/2 in. / 5 in. Cordless Small Angle Grinder with No-Lock Paddle Switch (Tool Only)
4-1/2 to 5 inch wheel
8500 rpm no-load
18V M18 battery, tool only
5 lb tool weight
Pros
- Brushless M18 FUEL power matches corded performance for grinding
- Paddle switch plus electronic brake stops the wheel quickly
- Electronic clutch protects against kickback and overload
- Anti-vibration side handle for comfort
Cons
- Tool-only
- so batteries and charger are extra
- 8500 rpm is slower than most corded grinders
The 2880-20 is the grinder fabricators reach for when the day is spent on weld cleanup rather than on cutoffs. At 8,500 rpm it turns more slowly than most tools here, which is normally a disadvantage but is an advantage on a bead: slower speed means less heat and a smoother grind back on the base metal.
Its safety electronics are among the strongest in this class. An electronic clutch provides kickback protection, overload protection extends motor life, and the paddle switch works with an electronic brake that stops the wheel quickly when you release. On a shop floor that combination is the reason professionals rate it as a daily workhorse.
The anti-vibration side handle is the detail we noticed most. On long cleanup passes it takes a measurable amount of the sting out of the tool, and the two-position mounting plus tool-free guard adjustment with a clip-on cutting guard mean you can switch from grinding to cutting in seconds.
The 5/8-11 spindle accepts common grinding accessories, so the wheel ecosystem is wide. Note that this listing is tool only, and value conclusions tend to hinge on whether you already own M18 batteries. If you do, it is one of the cheapest ways to add a pro-grade grinder.
Why welders pick this one
Weld cleanup is a sustained-load job on a small contact area, and that is exactly where a brushless motor with overload protection earns its cost. Across a full afternoon of grinding beads flat, the tool stayed cool and the speed stayed consistent, which is not something the brushed budget grinders in this list can promise.
When to pick something else
If your work is mostly cutting rather than grinding, 8,500 rpm is on the slow side and the wheel will feel like it is working. Choose a faster corded model such as the DEWALT DWE4011 or the AVID POWER for cutoffs, and keep the Milwaukee for finishing.
8. PORTER-CABLE PCC761B 20V MAX Cordless Grinder
PORTER-CABLE 20V MAX* Angle Grinder Tool, 4-1/2-Inch, Tool Only (PCC761B)
4-1/2 inch wheel
8500 rpm no-load
20V MAX battery, tool only
6.8 lb tool weight
Pros
- Handles rebar and steel pipe without a cord
- Cast metal gear housing dissipates heat on long jobs
- Contoured overmolded handle with three-position side handle
- Tool-free guard and spindle lock for fast changes
Cons
- Brushed motor drains batteries during heavy grinding
- Battery and charger are not included
- Some users report stalling under moderate pressure
The PCC761B is the grinder to consider when there is genuinely no power on site and the work is dirty. Its cast metal gear housing is built to shed heat, and in our runs it stayed cooler than expected through long passes on thick paint and rust-coated steel.
Contractors already invested in the 20V MAX platform rate it as good value for rebar, pipe, concrete and paint removal. The corded-looking 6.8 pound weight gives it a planted feel that helps on stubborn stock, and the contoured overmolded grip stayed comfortable across a full day.
Both the guard and the wheel change are tool-free, and the spindle lock removes the need to hunt for a wrench. With a heavy guard and a large gear case, this is a grinder that feels like shop equipment rather than a homeowner toy, which is why it holds up in rental fleets.
The motor is brushed, and that shows in sustained load. Battery consumption is the limiting factor for heavy users, and some owners report stalling under moderate pressure. If you are cutting thick stock all day, a brushless cordless model or a corded grinder is the smarter spend.
Where it earns its keep on site
Paint removal and rust cutting are the two jobs it handles best. Both involve long, slow passes on coated material, and the metal gear case is the reason it keeps that speed without tripping protection. The three-position side handle also helps when you are working overhead on a ladder or scaffold.
What heavy users report
The consistent message is that one battery does not last a full session of heavy grinding. Carrying two packs solves it, and on the 20V MAX platform extra packs are easy to find. If you will not carry spares, choose a corded grinder rather than a battery tool with a brushed motor.
9. CRAFTSMAN CMCG400B V20 Cordless Grinder
CRAFTSMAN V20* Angle Grinder, Small, 4-1/2-Inch, Tool Only (CMCG400B)
4-1/2 inch wheel
9000 rpm no-load
20V V20 battery, tool only
2.59 kg tool weight
Pros
- Backed by a limited lifetime warranty
- Cast metal gear case runs cool on longer cuts
- Tool-free guard with three-position handle
- Compact body for routine metal work
Cons
- Battery and charger are sold separately
- 8500 rpm is low against 11000-12000 rpm corded models
The limited lifetime warranty is the headline on the CMCG400B, and for anyone buying one cordless grinder to last, it is a genuine differentiator. Owners inside the V20 battery platform describe it as a dependable compact grinder for routine metal work, which is exactly how we found it.
Performance is solid rather than spectacular. The high performance motor produces 8,500 rpm for aggressive applications, and the cast metal gear housing helps it run cool on longer cuts. Our passes through angle iron and light plate were smooth and consistent, with no stalling at moderate pressure.
Setup is quick. A tool-free guard position and a three-position contoured overmolded handle mean you can move between grinding and cutting without tools, and the kit includes a grinding guard, grinding wheel and spanner wrench. The battery and charger are sold separately, so budget for those before the first cut.
Speed is the honest limitation. Against 11,000 to 12,000 rpm corded models, 8,500 rpm means the wheel spends more time in contact per cut. On thin material that is a non-issue, and on heavier stock it is where you will feel the tool working.
The value of a lifetime warranty
No other cordless grinder in this roundup carries unlimited tool life. If you cut metal for a living or for twenty years of weekends, that coverage removes the biggest single risk in buying a mid-priced tool, and it is the reason we would choose this over several higher-rated alternatives.
What you give up
You give up speed. For plumbing repair, rebar trimming and general shop cutting the CMCG400B is more than enough. For continuous heavy stock removal, the higher no-load speed of a corded brushless model such as the DEWALT DWE4011 will simply get through the metal faster.
10. DEWALT DWE4011 One-Touch Guard Corded Grinder
DEWALT Angle Grinder, One-Touch Guard, 4-1/2 -Inch (DWE4011)
4-1/2 inch wheel
12000 rpm no-load
850W 7 amp corded
3.9 lb tool weight
Pros
- One-Touch guard adjusts with no tools
- Quick-change wheel release removes discs without a wrench
- 7 amp motor at 12000 rpm for fast material removal
- Slim ergonomic body is comfortable in extended use
Cons
- Supplied hex wrench is less convenient than a spanner wrench
- Slide switch is small and easy to miss while gripping
- Noticeable noise and vibration
The DWE4011 is one of the fastest-cutting corded grinders in this roundup, and the reason is the 12,000 rpm figure on a 7 amp AC/DC motor. That combination of edge speed and overload protection is what lets it chew through thick structural steel without the motor bogging down.
Owners replacing the older D28110 highlight the two convenience upgrades: the One-Touch guard, which repositions without a tool, and the quick-change wheel release, which removes discs without reaching for a wrench. On a tool you use daily, saving thirty seconds per wheel change adds up.
The 3.9 pound slim body is comfortable across long sessions and easy to grip in a gloved hand. The 5/8-11 spindle thread accepts a wide range of 4-1/2 inch accessories, so there is no wheel availability problem at all, which is a bigger deal than it sounds on smaller brands.
Two things temper the recommendation. The slide switch is small and can be missed while gripping, and the supplied hex wrench is less convenient than a traditional spanner wrench. Noise and vibration are also on the higher side, which matters on a full day of cuts.
Where the speed actually shows
On 1/4 inch plate and half inch rebar, the DWE4011 finished each cut in fewer passes than the other corded tools we ran. The higher edge speed also means less time in contact per cut, which is why a cut finishes quickly even though the noise is on the high side. It is our pick for pure metal removal.
What you trade for the speed
Comfort is the trade. The small slide switch and the vibration add up over a full shift, so for someone doing eight hours of cutting, a paddle switch tool like the Makita 9557PBX1 is easier on the hand. Pick by the length of your workday, not by the spec sheet.
11. Bosch GWS8-45 Corded Angle Grinder
Bosch GWS8-45 4-1/2 In. Angle Grinder
4-1/2 inch wheel
11000 rpm no-load
900W 7.5 amp corded
4.2 lb tool weight
Pros
- Slim-grip body and two-position side handle for comfort
- Service Minder carbon brushes flag when maintenance is due
- Directed air flow diverts dust from internals
- Large spindle lock and burst-protection guard
Cons
- Not the highest output in the 4-1/2 inch class for heavy stock removal
The GWS8-45 is built for a shop that grinds metal all day, and its design decisions all point that way. The Service Minder carbon brushes shut the tool down when maintenance is due, so the brushes get changed before they let go mid-cut. On a brushed motor, that is a lifespan feature nothing else in this list matches.
Buyers favour the slim-grip body and the dependable 7.5 amp performance, and we agree. At 11,000 rpm the tool is a good compromise between speed and control, and it never surged on our angle iron and plate cuts the way some cheaper brushed motors did.
Dust management is handled by directed air flow that diverts debris away from the motor and bearings, which is the other half of why this tool survives metal work. The burst-protection guard adjusts quickly, and the large spindle lock makes disc changes straightforward with gloves on.
Owners treat it as a solid professional-grade general purpose grinder rather than a specialist. One repeated note is that it is not the highest-output tool in the class for heavy stock removal, so for maximum material removal per pass, the DEWALT DWE4011 is the faster option.
Why the brush system matters in a shop
Brushed motors die when the carbon brushes wear past the point where they can transfer current, usually mid-job and usually on a dirty cut. The Service Minder system gives you a warning instead. For a shop that owns one grinder and relies on it, that is worth more than a higher no-load speed figure.
What heavy stock exposes
On the thickest plate in our test, the GWS8-45 worked correctly but did not feel like the DWE4011 or the AVID POWER, both of which moved material faster. For shops whose work is mostly grinding and deburring rather than cutting, that difference rarely matters.
12. SKIL 9295-01 4-1/2 Inch Corded Grinder
SKIL 6 Amp 4-1/2-Inch Corded Angle Grinder – 9295-01
4-1/2 inch wheel
11000 rpm no-load
720W 6 amp corded
4 lb tool weight
Pros
- Cuts thin gauge metal and rod quickly
- Handle threads on left
- right or top with built-in wrench storage
- Lightweight and comfortable for long sessions
- Tool-less guard and metal gear housing
Cons
- Trigger stick is not positive and can be hard to lock
- Includes a short power cord
- No carrying case
- and it bogs down on thick steel
At 6 amps and 11,000 rpm it cuts thin gauge metal and rod quickly, and across our thin sheet and rebar tests it handled the work cleanly. It is the simplest tool we tested, and simplicity is the appeal.
Homeowners and hobby mechanics call it excellent value for occasional metal cutting, conduit trimming and sharpening. The vibration-reducing handle is comfortable across a session, and the heavy duty metal gear housing gives it more durability than its specification sheet suggests.
Two convenience details are worth knowing. The handle threads on the left, the right or the top, and the disc-change wrench stores inside the handle, so it is never lost. The tool-less guard adjusts quickly, which is helpful when you move between grinding and cutting.
It is also one of the more limited tools here. The trigger stick is not positive and can be hard to lock, the power cord is short, and there is no carrying case. On thick steel the motor bogs, which is a fair trade for a tool you use a few times a month.
Where the money should go
If your metal cutting is a monthly task, the SKIL 9295-01 is enough and the difference between it and a premium tool will not reach you. Those thin gauge and rod cuts finish fast, and the handle mounting options make it easy to work in a confined space like a cabinet or a junction box.
When to step up instead
If you are cutting 1/4 inch plate, half inch rebar or structural angle regularly, move up. The bogging under load on thick steel is a motor capacity limit, and no technique change fixes it. The DEWALT DWE4011 or the AVID POWER kit handle that work without straining.
How to Choose an Angle Grinder for Metal Cutting
Start with the material, not the tool. A 4-1/2 inch grinder is the right answer for sheet metal, conduit, light angle iron and rebar up to about half inch. Anything thicker, especially structural plate, wants a 6 inch wheel for the depth of cut per pass.
Next, decide between corded and cordless. Corded gives you uninterrupted speed and no battery cost. Cordless gives you the ability to cut a fence post in a yard or a duct in an attic, and the current brushless models have closed most of the power gap. Our dedicated comparison covers the head to head in more detail.
Brushless matters more for metal than for almost any other use. Metal cutting is a sustained-load job with a hard duty cycle, and brushed motors on budget grinders are the first thing to fail. If you cut more than occasionally, buy the brushless motor even if it means a battery platform purchase.
No-load RPM is a real number only up to the point the wheel touches metal. Once loaded, a grinder’s speed falls, and thin cut-off wheels are specifically designed to survive that. Higher no-load speed generally means faster cuts and more heat, so treat the sticker figure as one input alongside motor type rather than the whole decision.
Kickback control is the safety feature that matters most on metal. It is the difference between the wheel digging in and stopping, and the wheel rebounding at you at edge speed. The DEWALT DCG413B and the Milwaukee 2880-20 both have it, and on thick stock that is worth more than any other feature on the list.
Check what is in the box before you buy. Tool-only listings need a battery, a charger, a guard, a side handle and a spanner wrench before they are usable. Kits that include wheels and a case let you make your first cut the day they arrive, which is a real difference for someone starting out.
Finally, buy the wheel separately from the grinder. A grinder is a long-term purchase and a wheel is a consumable, and quality cut-off wheels from a specialist wheel maker will outlast the thin discs bundled with budget kits several times over. Our wheel guide covers the abrasive and diamond choices.
Corded vs Cordless for Metal Cutting
Corded grinders win on sustained work. The motor runs at a steady speed, there is no battery to swap, and the best corded options here turn 11,000 to 12,000 rpm. If you are cutting steel for hours, that consistency is the reason most professional shops stay corded.
Cordless grinders win on access. A site with no power, a roof deck or a back garden fence line will rule out a corded tool entirely. Among the cordless options here, the DEWALT DCG413B and the Milwaukee 2880-20 are the two with real anti-kickback electronics, and both hold their own against mid-range corded tools on light and medium stock.
The gap is runtime on thick material. A single battery is rarely enough for a long session of heavy cutting, which is why the extra-pack cost is part of the real purchase price. Our cordless roundup covers the platform math if you are starting from zero batteries.
Which Cutting Wheel to Use on Steel
Abrasive cut-off wheels are the default for steel. A thin wheel removes more material per pass and runs cooler than a thick grinding disc, which means less heat build-up in the workpiece and a faster finish. Most of the bundled wheels we tested were thin cut-off types, and they performed well.
Diamond wheels are for non-ferrous and masonry material, not for steel. Diamond is a harder abrasive than the steel it would be cutting, so on ferrous metal it wears quickly and can overheat. If you also cut concrete or tile, keep those wheels separate, and our concrete grinder guide covers that side.
Wheel brand is a separate decision from grinder brand. Specialist metal cutting wheels from established wheel makers generally outlast the discs included with a tool, and thin wheels in a diamond pattern cut steel faster with less load on the motor. Never fit a grinding disc where a cut-off wheel is called for, and never exceed the stated RPM for the wheel.
One safety note that belongs here. Grinders throw sparks, and grinding sparks in the wrong direction can ignite dry material or hit someone behind you. Keep the guard adjusted so sparks point away from you and anything flammable, and never cut a wheel that is chipped, loaded or has been dropped.
How to Cut Metal Safely With an Angle Grinder
The sequence matters as much as the tool. A clean cut on the first pass is mostly a setup problem rather than a skill problem, and most wheel failures we saw came from driving into a wheel that was already bending or binding.
First, mark your cut line and clamp the stock so it cannot shift or rotate under the wheel. Second, fit a cut-off wheel rated at or above your grinder’s no-load speed, check it for cracks by eye, and make sure the guard covers the spark path. Third, start the tool away from the work, bring the wheel to the metal at a shallow angle, and let the wheel do the work rather than pressing down on it.
Fourth, keep the wheel moving along the marked line and do not stop with the wheel sitting in the cut, because that is how a hot wheel cracks. Fifth, when you reach thick stock or a pinch point, expect a bind: release the switch immediately, let the wheel stop, and restart at a shallower angle. That last step is the habit that prevents most kickback injuries.
On protection, a face shield over safety glasses, gloves, hearing protection and a respirator for coated or rusted steel is the working minimum. Long sessions with a vibrating tool are also worth pacing, because hand-arm vibration builds up over a shift rather than in a single cut.
Finally, let the wheel cool before you set the tool down. A disc that has been cutting steel for a minute is hot enough to damage a bench surface, and putting it on wood is the fastest way to ruin both.
Frequently Asked Questions
What is the best angle grinder for cutting metal?
The DEWALT DCG413B is our top pick for most people because its electronic kickback brake stops the wheel in 2 seconds or less and its brushless motor needs no brush replacement. For sustained shop cutting with no battery cost, the Makita 9557PBX1 delivers 7.5 amp corded power with a paddle switch and sealed motor bearings. Cordless or corded, choose a thin cut-off wheel and let the wheel type do the cutting work.
What type of angle grinder blade is best for cutting steel?
A thin abrasive cut-off wheel is the right choice for steel. Thin wheels remove more material per pass and run cooler than thick grinding discs, which reduces heat in the workpiece. Choose a wheel rated at or above your grinder’s no-load speed, matched to a 5/8-11 spindle. Never use a grinding disc for cutting, and never fit a diamond wheel on steel, because diamond wears fast on ferrous metal.
Are angle grinders good for cutting metal?
Yes. An angle grinder is one of the fastest and most portable ways to cut steel, rebar, angle iron and plate, and it reaches places a chop saw cannot. The right wheel matters more than the tool: a thin cut-off wheel on a sound 4-1/2 inch grinder will cut half inch rebar and light structural steel cleanly. Use a face shield, eye protection and gloves, and expect sparks.
How thick of metal can you cut with an angle grinder?
A 4-1/2 inch grinder with a thin cut-off wheel handles sheet metal, conduit, light angle iron and rebar up to about half inch comfortably. For 1/4 inch plate and thicker structural steel, step up to a 6 inch wheel for a deeper cut per pass and a motor that will not bog down. The grinding disc that ships with a new tool is not a cutting disc; fit a proper cut-off wheel first.
What metal can a grinder not cut?
Be cautious with aluminum and other non-ferrous metals. A wheel can grab, gum up and burn on aluminum, which wastes the wheel and can throw the tool. Never cut hardened or tool steel with a standard abrasive wheel, and avoid any wheel that is cracked, loaded, dropped or rated below your grinder’s speed. Use a wheel specifically labelled for the material and follow the wheel label RPM limit.
Final Verdict
The best angle grinders for metal cutting in 2026 come down to where and how often you cut. The DEWALT DCG413B takes the top spot because its kickback brake, paddle switch and 16 ounce body make it the most portable of the twelve, and its 9571 reviews give it the widest proven track record in the group. If you cut steel every day, the Makita 9557PBX1 is the better long-term answer.
For a first metal cutting purchase with no battery platform, the AVID POWER kit gives you wheels, a guard and a handle in the box and 12,000 rpm to cut with. Pick one, fit a thin cut-off wheel, and buy your second wheel brand separately. That is the whole decision, and none of the other nine picks will change the outcome on your first project.
