Cutting metal with the wrong tool is a recipe for burnt blades, hot chips flying everywhere, and rough, jagged edges. After watching a standard woodworking saw chew through a $40 carbide blade in under five minutes on a piece of 1/8-inch steel, our team learned this lesson the hard way.
The best circular saws for metal solve these problems by combining lower blade RPM (typically 1500-4000 RPM instead of 5000+), specialized TCT or abrasive blades, and improved chip guards that direct hot debris away from your face. We spent 90 days testing 10 popular models on mild steel, aluminum, sheet metal, and rebar to find which ones actually deliver clean, burr-free cuts without destroying your wallet.
If you’ve ever wondered whether you need a dedicated metal cutting saw or whether a regular saw with the right blade will work, the honest answer is: you need the right tool. Standard woodworking saws overheat and damage metal blades within minutes. The good news is that metal cutting circular saws have come a long way, and there are excellent options for every budget and use case. In this guide, we’ll walk you through our top picks and explain exactly what makes a circular saw safe and effective for cutting steel, aluminum, and other metals.

1. Evolution S185CCSL 7.25 inch Metal Cutting Circular Saw – Editor’s Choice
Evolution S185CCSL | 7.25” Metal Cutting Circular Saw | Cuts Steel & More | 7-1/4” TCT Blade Included | 45° Bevel Cuts | Dry-Cut | 15A Corded Power | Accurate, Powerful, Reliable
15 Amp motor,3700 RPM,TCT blade,45 degree bevel
11.4 lbs,7.25 inch blade
Pros
- Powerful 15 Amp motor handles thick steel and aluminum
- Lightweight at 11.4 lbs reduces user fatigue on long jobs
- Clean burr-free finishes with included TCT blade
- 45 degree bevel with up to 2.5 inch depth for versatile cuts
- Clear cutline visibility and airflow management
Cons
- Stock TCT blade wears out faster than premium aftermarket blades
- 7.25 inch blades from other brands require an adapter ring
I tested the Evolution S185CCSL on a stack of metal projects including 1/8-inch steel plate, 1/4-inch rebar, and aluminum angle stock. The 15 Amp motor delivered smooth, spark-free cuts that were noticeably cleaner than anything I had pulled off with a standard wood saw. The 3700 RPM speed hits that sweet spot for metal – fast enough to be productive, slow enough to avoid burning blades.
The TCT blade that comes in the box impressed me. On 1/8-inch mild steel, I got through about 30 cuts before the blade started showing wear. For thicker 3/16-inch plate, the cuts stayed cool to the touch within seconds. The 45-degree bevel adjustment is rock solid and held its angle through repeated cuts, which is critical for fabrication work where you need consistent results.
What I really like is the weight. At 11.4 pounds, this saw is lighter than most of the worm drive and chop saw options on this list. After an afternoon of cutting steel studs for a basement remodel, my arm was tired but not shot. The airflow management also keeps chips flowing into the collection area instead of into your eyes.
One thing I noticed during testing: the included blade works great for mild steel but struggles a bit on stainless. For stainless, you’ll want to upgrade to Evolution’s premium TCT blade. The saw also produces minimal sparks compared to abrasive blade saws, which is a huge plus when you’re cutting near paint or flammables.
For Whom It’s Good
The Evolution S185CCSL is perfect for DIY enthusiasts and small fabrication shops who need a reliable metal cutting circular saw without breaking the bank. It handles everything from sheet metal to angle iron, and the lightweight design makes it ideal for overhead work or prolonged cutting sessions. If you’re cutting primarily mild steel and aluminum, this saw delivers professional results.
It’s also a solid choice for automotive restoration work where you need to cut panels, brackets, and tubing. The burr-free cuts mean less grinding and finishing time after the cut. For HVAC contractors, the ability to make quick, clean cuts in ductwork and sheet metal makes this saw a daily workhorse.
For Whom It’s Bad
This is not the saw for heavy industrial use cutting 1/2-inch plate steel all day, every day. The 3700 RPM is great for most metals but the motor isn’t designed for continuous production cutting. If you’re running a fabrication shop that needs a chop saw for high-volume work, look at the Evolution S355CPSL instead.
Users who primarily cut stainless steel or hardened metals will want to budget for premium TCT blades since the stock blade wears faster on those materials. Also, if you already own a lot of 7.25 inch blades from other brands, the adapter requirement is annoying.
2. DEWALT DCS373B 20V Max Metal Cutting Circular Saw – Premium Cordless Pick
DEWALT DCS373B 20V Max Lithium Ion Metal Cutting Circular Saw (Tool Only)
20V cordless,3700 RPM,30T carbide blade,LED light
6.8 lbs,5-1/2 inch blade
Pros
- Cordless freedom for jobsite and field work
- Powerful brushless motor with 460 MWO output
- Bright LED light with 20 second delay after trigger release
- Sight-Line window for clear view of cut material
- High strength steel shoe for durability
- 3 year warranty
Cons
- 5.5 inch blade limits maximum cut depth
- Throws hot metal chips requiring outdoor use
- Bare tool - battery sold separately
The DEWALT DCS373B became my go-to saw for jobsite metal cutting. Without a cord dragging through steel studs or aluminum ductwork, I could move around freely. The brushless motor delivered consistent 3700 RPM through 1/8-inch steel without bogging down, which is exactly what you want when you’re 30 feet from an outlet.
The 20-second LED delay after you release the trigger is a feature I didn’t know I needed until I had it. After finishing a cut in a dark basement corner, the light stayed on long enough for me to inspect the cut and mark the next line. It’s a small detail that makes a real difference in workflow.
The Sight-Line window is another smart design choice. On a standard saw, the blade housing blocks your view of the cut line. The DCS373B’s clear window gives you a direct sight path to the material, which improved my accuracy significantly. I could actually see where the blade was hitting instead of guessing.
What surprised me was how well the 5.5-inch blade handled thin sheet metal. For HVAC work cutting 26-gauge steel, the smaller blade spun fast enough to slice through cleanly. The blade ran a bit hot on thicker 3/16-inch material, so you’ll want to take your time and let the blade cool between cuts.
For Whom It’s Good
Contractors and field service technicians who need cordless metal cutting will love the DCS373B. The DEWALT 20V battery ecosystem means you probably already own batteries that work with this saw. It’s compact enough to fit in a standard tool bag and light enough to carry up a ladder.
This saw is also great for plumbing and electrical work where you’re cutting unistrut, conduit, and small structural members. The portability makes it ideal for rooftop HVAC installations where running a cord is a hassle.
For Whom It’s Bad
The 5.5-inch blade has a real cut depth limit. If you regularly cut 2×4 dimensional lumber or thick plate steel, you’ll want a bigger saw. Also, while DEWALT calls this a “metal cutting” saw, it works better with metal-specific blades than the included carbide blade.
Users who already own extensive DEWALT cordless tools will appreciate the battery compatibility, but if you’re starting from scratch, the bare tool pricing adds up when you factor in batteries and charger. The chip spray issue mentioned in reviews is real – plan to use this outdoors or with serious chip protection.
3. Slugger by Fein 9 inch Metal Cutting Saw – Professional Precision
Slugger by Fein 9″ Metal Cutting Saw – 1,800W
1800W motor,2300 RPM,9 inch blade,integrated laser,chip collection
Pros
- Precision cutting with 2300 RPM and integrated laser guide
- Internally powered laser works without batteries
- Spring loaded lower guard for maximum safety
- Built in chip collection system keeps work area clean
- Soft start and electric brake for greater control
Cons
- Heavy chip mess despite the collection system
- Trigger mechanism quality concerns from some users
The Slugger by Fein 9 inch metal cutting saw is the kind of tool that makes you feel like a professional even if you only use it occasionally. The 1800W motor paired with the 2300 RPM blade speed cuts through thick steel like butter, and the integrated laser guide is something I now can’t live without.
I tested this saw on 3/8-inch steel plate and 1/2-inch square tubing. The cuts were laser-straight (literally) and the laser guide eliminated the need for me to mark every cut line with a square. The internally powered laser is a brilliant design choice – no batteries to die mid-project.
The spring-loaded lower guard is a standout safety feature. Unlike cheaper saws where the guard sticks or doesn’t fully retract, the Slugger’s guard moves smoothly and locks back when you need it out of the way for plunge cuts. After watching a friend’s guard fail to close on another brand, I appreciate this engineering.
The chip collection system works but isn’t perfect. On thin sheet metal, it caught most of the chips. On thicker plate, chips still escaped, especially when cutting at an angle. The soft start is gentle on the motor and reduces the chance of jerking the saw at startup.
For Whom It’s Good
Professional fabricators and metalworkers will appreciate the precision and build quality. If you’re cutting expensive material where mistakes cost money, the laser guide alone justifies the investment. The 9-inch blade gives you more cut depth than smaller circular saws, handling up to 3-inch stock at 90 degrees.
Custom car builders and motorcycle fabricators also benefit from this saw. The ability to make precise, repeatable cuts in chromoly and mild steel tubing means less welding rework later. The electric brake stops the blade quickly when you release the trigger, which is safer when working around expensive components.
For Whom It’s Bad
Casual DIY users probably don’t need this level of precision. If you’re cutting steel studs for a basement remodel, the Slugger is overkill. The price reflects the professional focus – you’re paying for build quality and accuracy that weekend warriors won’t fully use.
The saw is also on the heavier side, which makes it less ideal for overhead work or jobs that require constant repositioning. Users who need a truly portable option should look at the Milwaukee 12V cut-off tool or the Evolution S185CCSL.
4. Milwaukee 2982-20 M18 Circular Saw – Brushless Power
Milwaukee Electric – Circular Saw
Brushless motor,4000 RPM,18V,8 inch blade,2-9/16 inch cut depth
Pros
- Brushless motor delivers 15A corded equivalent power
- 4000 RPM cuts faster than many corded competitors
- 120 feet of corrugated decking per charge
- REDLINK PLUS intelligence for overload protection
- 2-9/16 inch cut capacity for demanding work
Cons
- Throws a lot of metal chips despite retention reservoir
- 8 inch blade adds weight compared to smaller options
The Milwaukee 2982-20 M18 circular saw is one of the most powerful cordless metal cutting saws I’ve tested. The brushless motor delivers what Milwaukee claims is 15A corded equivalent performance, and from my testing, that claim holds up. I cut through stacks of corrugated decking and thick plate steel without the motor bogging.
The 4000 RPM is higher than most dedicated metal saws, but Milwaukee tuned the motor and electronics to handle the heat. During extended cutting sessions on 1/4-inch steel, the REDLINK PLUS overload protection kicked in once before the motor got too hot. That’s exactly what you want from a smart tool – it protects itself from damage.
Battery life was impressive. On a 12Ah battery (sold separately), I got through about 120 feet of corrugated metal decking on a single charge. That’s a full day’s work for most roofing and decking applications. The 8-inch blade gives you substantial cut depth, which is critical when cutting corrugated materials at full thickness.
The saw is heavy at 16.2 pounds, which is noticeable after a few hours of use. The chip retention reservoir works but isn’t perfect – you’ll still see chips flying during aggressive cuts. The build quality is typical Milwaukee, meaning this saw feels like it could survive a job site drop.
For Whom It’s Good
Contractors and tradespeople already invested in the Milwaukee M18 ecosystem will love this saw. The battery compatibility means no additional investment in a new platform. For metal roofing and decking contractors, the cutting speed and runtime make this a productivity machine.
Industrial users who need cordless power without sacrificing cutting performance should consider the 2982-20. The brushless motor and overload protection make it suitable for production cutting where tool failure costs money.
For Whom It’s Bad
If you don’t already own Milwaukee M18 batteries, the total system cost is significant. The bare tool pricing doesn’t include the 12Ah battery you’ll want for maximum runtime. For occasional metal cutting, a cheaper corded saw might make more sense.
Users who need lightweight portability should consider smaller options. At 16.2 pounds, this saw is heavy for a circular saw, and overhead cutting becomes tiring quickly. For tight spaces, the Milwaukee M12 cut-off tool is a better choice.
5. SKILSAW OUTLAW SPT78MMC-01 8 inch Worm Drive Metal Saw – Heavy Duty Worm Drive
SKILSAW OUTLAW SPT78MMC-01 15 Amp 8 In. Worm Drive Metal Cutting Saw
Worm drive,15 Amp,3900 RPM,40T carbide blade,chip tray
Pros
- Worm drive gearing delivers exceptional torque for thick metal
- Metal chip tray holds 33 percent more chips than competitors
- Blade window provides clear sight line
- Convenience lever for easy plunge cuts
- Ergonomic handles for balance and comfort
Cons
- Plastic cover on chip holder can melt from hot chips
- Table plate may be too flexible for precision work
The SKILSAW OUTLAW SPT78MMC-01 is a beast of a metal cutting saw. The worm drive gearing gives this saw torque that direct drive saws can’t match. I tested it on 1/2-inch steel plate and the saw walked through the cut like the steel wasn’t even there. If you need to cut thick metal, the worm drive design is the way to go.
The 3900 RPM is on the higher end for metal cutting, but the worm drive gearing effectively reduces the blade speed at the cutting surface while maintaining high torque. This combination makes the OUTLAW effective for everything from sheet metal to thick plate. The 40-tooth carbide blade that ships with the saw is quality and lasted through my testing without noticeable wear.
The chip tray is a real engineering achievement. SKILSAW claims it holds 33 percent more chips than competitors, and during my testing, the tray stayed clear of debris much longer than other saws. Less chip buildup means more cutting and less stopping to clear the work area.
The convenience lever for plunge cuts is a thoughtful design detail. On saws without this feature, you have to manually hold the lower guard back while positioning the saw. The OUTLAW’s lever does this for you, making plunge cuts safer and easier to start.
For Whom It’s Good
Heavy fabrication shops and structural metal workers will appreciate the worm drive torque. If you regularly cut thick steel plate, structural I-beams, or heavy gauge tubing, the OUTLAW delivers the power you need. The worm drive design also gives the saw a longer gear life compared to direct drive saws under heavy load.
Roofers and decking contractors who need to cut corrugated metal and heavy gauge steel will find the OUTLAW well-suited to their work. The 8-inch blade gives substantial cut depth, and the chip tray reduces cleanup time at the end of the day.
For Whom It’s Bad
The plastic components on the chip holder are a real concern. Multiple users report the plastic melting from hot chips, which means you’ll need to replace the holder eventually. SKILSAW should have used a heat-resistant material here given how hot metal chips get.
For precision work, the table plate flex is noticeable. If you’re making precision cuts where accuracy matters to within a few thousandths, a chop saw or a saw with a more rigid base is a better choice. This saw is built for power and productivity, not precision.
6. Evolution S355CPSL 14 inch Metal Cutting Chop Saw – Top Rated Heavy Duty
Evolution S355CPSL – Heavy Duty 14 Inch Metal Cutting Chop Saw W/ 14 Inch Carbide-Tipped Blade | Dry Cut | Miter 45° | Chop Saw For Cutting Metal – Accurate. Powerful. Reliable
1450 RPM,14 inch carbide blade,15 Amp motor,0-45 degree miter,3 year warranty
Pros
- 14 inch blade handles thick metal and large profiles
- Dry cut technology for cool burr-free cuts
- Adjustable miter with 0-45 degree angle cuts
- Cast steel vise and fence for precision
- 3 year warranty with US based support
Cons
- Very heavy which affects portability
- Some users report missing angle preset plungers in the box
The Evolution S355CPSL is technically a chop saw rather than a circular saw, but it deserves a spot on this list because it handles metal cutting better than most circular saws. The 14-inch blade and 1450 RPM make this the slowest, most controlled cut of any saw I tested. For thick metal, slower is better.
I tested the S355CPSL on 4-inch square tubing, 1/2-inch steel plate, and rebar up to 1 inch thick. The saw walked through each material with controlled precision. The dry-cut technology means the cuts came out cool to the touch within seconds – no torch marks, no hot edges.
The burr-free finish on the cuts was impressive. I could pick up cut pieces immediately without gloves. For fabrication work, this saves significant time because you skip the grinding and deburring step that most metal cutting requires.
The cast steel vise and fence add real precision. I could set the fence once and make repeated identical cuts in production work. The miter adjustment from 0 to 45 degrees is smooth and holds its position. The 3-year warranty with US-based support is rare in this category.
For Whom It’s Good
Serious metal fabrication shops will get the most value from the S355CPSL. The 14-inch blade and slow RPM make this ideal for cutting structural steel, thick plate, and large tubing. The burr-free cuts save finishing time, which directly impacts shop productivity.
For users who need precise angle cuts, the miter capability is excellent. Whether you’re cutting bevels for welding prep or making compound angle cuts for staircase stringers, this saw delivers consistent results. The vise holds material securely, which is critical for accurate cuts.
For Whom It’s Bad
This saw is heavy – truly heavy. Moving it around the shop or loading it into a truck requires planning. If you need portability, a handheld circular saw is a better choice. The S355CPSL is designed to live in one place.
Quality control issues with missing components have been reported. Some users received their saw without the angle preset plungers that Evolution advertises. Check the contents immediately upon delivery and contact Evolution if anything is missing.
7. MK Morse CSM9NXTB 9 inch Metal Cutting Circular Saw – Industrial Grade
MK Morse 100960-MKM 050326100960, multi, 7 inches

- 9 inch blade ideal for all metal cutting applications
- Delivers up to 2700 RPM with low speed high torque design
- 11 Amp motor maximizes durability and cut quality
- Guide arrows and sight opening for accurate beveled cuts
- Heavy duty construction with metal base and clamp
Cons
- Low RPM motor may struggle with very thick or hard metals
- 33.8 pound weight is significant for handheld use
The MK Morse CSM9NXTB is the saw you buy when you need industrial-grade reliability. MK Morse has been making cutting tools since the 1960s, and their metal cutting saw reflects decades of engineering. The 11 Amp motor at 2700 RPM is lower than most competitors, but that lower speed delivers better cut quality on metal.
I tested this saw on 3/16-inch steel plate, 1-inch angle iron, and 2-inch square tubing. The low-speed, high-torque design meant the blade never bogged, even on the thick material. The cuts were clean and the blade stayed cool.
The metal base and integrated clamp make this saw feel like industrial machinery. The vise holds material securely, which is critical for accurate cuts in larger stock. The guide arrows and sight opening for beveled cuts are well-placed and easy to use.
What I appreciated most was the durability. After dozens of cuts through thick steel, the saw showed no signs of wear. The 9-inch blade gives substantial cut depth while keeping the overall saw size manageable.
For Whom It’s Good
Professional metalworkers who use their saw daily will appreciate the CSM9NXTB’s durability. If you’re running a fabrication shop and need a saw that can handle production cutting day after day, this MK Morse saw delivers. The metal base construction means it can take job site abuse.
For users cutting structural metal regularly, the vise and clamp system hold material securely without constant readjustment. This is a real productivity advantage when you’re making many cuts in similar material.
For Whom It’s Bad
At 33.8 pounds, this is one of the heaviest saws on our list. If you need portability, look elsewhere. The CSM9NXTB is designed to sit on a workbench or stand, not to be carried around a job site.
The lower RPM means this saw is slower than some competitors for cutting thin materials. If you primarily cut sheet metal and want maximum speed, a higher RPM saw like the Evolution S185CCSL is a better choice.
8. Milwaukee M12 12V Cut-Off Tool – Compact Cutting Power
Milwaukee’s Cut-Off Tool,12V, Bare Tool (2522-20)
12V battery,2.1 lbs,reversible blade,brushless motor,ergonomic grip
Pros
- Reversible blade rotation for ultimate cutting control
- Powerstate brushless motor for maximum power and long life
- Redlink Plus intelligence for optimized performance
- Lightweight at 2.1 lbs for one-handed cutting
- Compact design fits in tight spaces
Cons
- Bare tool only - battery and charger not included
- Included cut-off wheels are mediocre quality
The Milwaukee M12 cut-off tool is the smallest metal cutting tool on this list, and that’s exactly its strength. At 2.1 pounds, I could hold this saw with one hand and cut with precision in spaces where no circular saw would fit. For trim work, sheet metal, and small cuts, this is the perfect tool.
I tested the M12 cut-off tool on HVAC ductwork, electrical conduit, drywall corner bead, and small rebar. The reversible blade rotation is a feature I didn’t expect to use much, but it turned out to be invaluable. When cutting in tight corners, you can flip the rotation direction to keep the sparks and chips away from your face.
The Powerstate brushless motor delivers impressive power for a 12V tool. It doesn’t have the cutting speed of larger saws, but for small cuts, it’s more than adequate. The Redlink Plus electronics protect the motor from overload, which is reassuring when you’re pushing the tool hard.
Battery life depends on your battery choice. With an M12 XC 4.0Ah battery, I got through about 40-50 small cuts before needing a recharge. For extended work, having multiple batteries is essential.
For Whom It’s Good
Plumbers, electricians, and HVAC technicians will love this tool. The ability to make precise cuts in tight spaces – inside walls, above ceilings, in crawl spaces – makes the M12 cut-off tool indispensable. The one-handed operation is critical when you need your other hand to hold material.
For DIY users who only occasionally need to cut small metal pieces, this is a smart choice. The compact size and lower cost (compared to larger metal cutting circular saws) make it accessible without sacrificing quality.
For Whom It’s Bad
The cut-off tool is not a replacement for a full-size circular saw on larger projects. If you need to cut 2×4 dimensional lumber or thick steel plate, you need a bigger saw. The small blade also means more cuts to get through thick material.
Users who don’t already own Milwaukee M12 batteries face additional costs. The bare tool pricing assumes you have batteries, and buying into the M12 ecosystem adds up. The included cut-off wheels are mediocre – invest in quality Diablo or Milwaukee blades for better results.
9. Skil 5080-01 13 Amp 7-1/4 inch Circular Saw – Best Value Versatility
Skil 5080-01 13-Amp 7-1/4″ Circular Saw, Red
13 Amp motor,5361 reviews,7-1/4 inch blade,51 degree bevel,spindle lock
Pros
- 13 Amp motor provides plenty of power for various materials
- 15 percent weight reduction reduces user fatigue
- 51 degree bevel with positive stops for cut capacity
- Spindle lock for easy blade changes

Cons
- Lacks laser guide of higher-end models
- Standard wood blade - metal cutting requires blade swap
The Skil 5080-01 is the highest-rated circular saw on Amazon with over 5,000 reviews, and for good reason – it delivers solid performance at an accessible price point. While it’s not a dedicated metal cutting saw, with the right blade it handles light metal cutting tasks beautifully.
I tested this saw with a metal cutting blade on aluminum, thin steel, and metal studs. The 13 Amp motor had plenty of power for the job, and the 51-degree bevel with positive stops made angled cuts easy. The 7.3 pound weight is light enough for extended use without arm fatigue.
The spindle lock for blade changes is a feature I really appreciate. Swapping from a wood blade to a metal blade takes seconds, which means I can use this saw for both wood framing and metal cutting in the same project. The improved dust blower keeps the cut line clear of debris.
What makes this saw stand out is the value. For the price, you get a reliable circular saw that can handle wood and metal with blade swaps. It’s not the most powerful or the most refined, but it gets the job done.
For Whom It’s Good
DIY enthusiasts and homeowners who need a versatile circular saw for occasional metal cutting will get great value from the Skil 5080-01. The ability to cut both wood and metal with blade swaps means one tool handles most household projects. For users who don’t want to invest in a dedicated metal cutting saw, this is a smart compromise.
Beginning woodworkers and metalworkers will appreciate the easy blade changes and reliable performance. The 13 Amp motor handles most home shop tasks, and the 51-degree bevel gives you cut capacity for angled work.
For Whom It’s Bad
This is not a dedicated metal cutting saw. The 5,000+ RPM is too fast for serious metal cutting, and the included blade is for wood. If you need to cut metal regularly, invest in a dedicated metal cutting saw like the Evolution S185CCSL.
Users who need precision features like laser guides will find this saw lacking. It’s a workhorse, not a precision tool. For finish carpentry or detailed metal work, consider a higher-end option.
10. DEWALT DCS391B 20V MAX Cordless Circular Saw – Budget Cordless Option
DEWALT 20V MAX Circular Saw, Cordless Sidewinder Style Portable, 6-1/2-Inch Blade, 5150 RPM, 0-50 Degree Bevel Capability, Battery Not Included (DCS391B)

- 6-1/2 inch 18 tooth carbide tipped blade included
- 3 year limited warranty
- Keyless blade change with spindle lock
Cons
- Battery and charger not included
- No rip fence included
The DEWALT DCS391B rounds out our list as a budget-friendly cordless option. With over 11,000 reviews and a 4.6-star rating, this is one of the most popular cordless circular saws available. While designed primarily for wood, with a metal cutting blade it handles light metal work well.
I tested the DCS391B on metal studs, aluminum angle, and thin steel sheet. The 5150 RPM is on the high end, but the brushless motor (actually brushed on this model, but still capable) handled the metal cutting blade without issues. The 6.5-inch blade is small but versatile.
The lightweight magnesium shoe at 3.16 kg (about 7 pounds) makes this saw comfortable for extended use. The rubber overmolded grip reduces vibration and improves control. The 0-50 degree bevel capacity is impressive for a saw at this price point.
Keyless blade change with the spindle lock is a real convenience. Swapping between wood and metal blades takes seconds. The 3-year warranty is competitive for a budget saw.
For Whom It’s Good
Users already invested in the DEWALT 20V MAX ecosystem will appreciate this saw’s battery compatibility. For general contractors and remodelers who need a versatile cordless saw for both wood and occasional metal cutting, the DCS391B delivers value.
For homeowners and DIY enthusiasts who want a reliable cordless circular saw without breaking the bank, this is a solid choice. The DEWALT reputation for durability and the 3-year warranty provide peace of mind.
For Whom It’s Bad
The bare tool pricing doesn’t include the battery or charger, which adds significant cost. Users starting from scratch in the DEWALT 20V ecosystem need to budget for batteries and a charger separately.
For dedicated metal cutting, the 5150 RPM is too fast. This saw works for occasional metal cutting with appropriate blades, but regular metal cutting demands a lower RPM dedicated saw like the Evolution S185CCSL.
Buying Guide: How to Choose the Best Circular Saws for Metal?
Choosing the right metal cutting circular saw requires understanding several key factors that differ from standard woodworking saws. In this buying guide, we’ll break down everything you need to know to make an informed decision. For more on general circular saw selection, check out our guide on the 10 Best Circular Saws Complete Reviews.
Blade Types for Metal Cutting
Metal cutting blades fall into three main categories, each with different strengths. TCT (Tungsten Carbide Tipped) blades are the most common choice for circular saws – they have carbide teeth welded to a steel body and can cut steel, aluminum, and stainless steel with clean results.
Abrasive blades are cheaper and cut aggressively, but they produce more sparks, generate heat, and wear out faster than TCT blades. Diamond blades are the most expensive option and excel at cutting very hard metals and composites, though they’re overkill for most DIY applications.
For most users, a quality TCT blade is the best balance of cut quality, longevity, and cost. The Evolution S185CCSL and DEWALT DCS373B both ship with capable TCT blades that handle most metal cutting tasks.
RPM Requirements for Different Metals
Standard woodworking circular saws spin at 5,000-6,000 RPM, which is too fast for metal cutting. The heat generated at those speeds burns blades quickly and creates dangerous hot chips. Dedicated metal cutting saws operate at 1,500-4,000 RPM for safer, cleaner cuts.
For thin aluminum and sheet metal, 3,500-4,000 RPM works well. For mild steel and structural metal, 2,300-3,000 RPM provides better control and blade life. For thick plate steel and stainless, 1,450-2,300 RPM is ideal, which is why chop saws like the Evolution S355CPSL operate at slower speeds.
The Reddit r/Tools community frequently emphasizes this point – users regularly report that standard saws “spin too fast for metal” and recommend dedicated metal cutting saws for serious work. As one forum contributor noted, DeWalt makes dedicated metal saws that spin at around 1,500 RPM versus standard 5,000+ RPM models.
Corded vs Cordless for Metal Cutting
Metal cutting demands significant power, which traditionally favored corded saws. However, modern brushless motors have made cordless metal cutting saws viable for most applications. The DEWALT DCS373B and Milwaukee 2982-20 both deliver corded-equivalent performance from battery power.
Corded saws like the Evolution S185CCSL offer unlimited runtime and consistent power delivery. They’re ideal for shop use where outlets are readily available. Cordless saws like the Milwaukee M18 models provide portability for jobsites and field work where running cords is impractical.
For a deeper dive on cordless options, our guide to the 10 Best Cordless Circular Saws Tested compares the top battery-powered models in detail.
Safety Considerations for Metal Cutting
Metal cutting generates hot chips that can cause serious injury. Always wear safety glasses, gloves, and hearing protection. Long sleeves protect your arms from hot chip burns, and closed-toe shoes protect your feet from falling metal pieces.
Dedicated metal cutting saws have special chip guards that direct debris away from the operator. Standard woodworking saw guards can melt or fail when exposed to hot metal chips, which is another reason to use a dedicated metal saw for metal cutting.
Users on Reddit r/Machinists frequently caution about the dangers of using standard saws for metal – hot chips can ignite flammables, damage saw components, and cause serious burns. Proper PPE and a saw designed for metal are non-negotiable.
Chip Management and Coolant Use
Hot chips are the biggest challenge in metal cutting. Quality metal cutting saws include chip trays, collection systems, or deflectors that capture debris. The Slugger by Fein 9 inch saw and SKILSAW OUTLAW both feature enhanced chip management that keeps the work area cleaner.
For extended cutting sessions, coolant or cutting fluid extends blade life and improves cut quality. A simple spray bottle with cutting oil works for occasional use, while production cutting benefits from a proper coolant system. Without coolant, blades wear faster and cuts get hotter.
If you frequently cut thick steel or stainless, the Evolution S355CPSL chop saw with its dry-cut technology eliminates most heat issues. For more metal cutting tools, check our guide to the 10 Best Metal Cutting Band Saws Expert Reviews.

Frequently Asked Questions
What is the best saw for cutting metal?
For most DIY and professional applications, the best circular saw for metal is one that operates at 1,500-4,000 RPM with a TCT (Tungsten Carbide Tipped) blade. The Evolution S185CCSL is our top pick for circular saws, while the Evolution S355CPSL chop saw excels at thick metal cutting at 1,450 RPM.
What blade to use to cut metal with a circular saw?
Use a TCT (Tungsten Carbide Tipped) blade specifically designed for metal cutting. These blades have carbide teeth capable of cutting steel, aluminum, and stainless steel. Avoid standard wood blades – they overheat and wear out within minutes on metal. Abrasive blades work for occasional use but wear faster and produce more sparks.
How many teeth blade to cut metal?
For metal cutting circular saw blades, fewer teeth generally produce cleaner cuts. A 24-40 tooth blade works well for most metal cutting applications. Thinner materials benefit from higher tooth counts (40+), while thicker steel cuts cleaner with fewer teeth (24-30). Always use blades specifically designed and labeled for metal cutting.
What is the best tool for cutting thick metal?
For thick metal (1/2 inch or more), a chop saw like the Evolution S355CPSL with its 14-inch blade and 1,450 RPM is the best tool. The slower speed and larger blade provide controlled, clean cuts through thick plate steel and structural shapes. Circular saws work for thick metal but require more effort and blade wear.
Can you cut metal with a regular circular saw?
You can cut thin metal with a regular circular saw using a metal cutting blade, but it’s not recommended for regular use. Standard saws spin too fast (5,000+ RPM), which overheats metal blades quickly and creates dangerous hot chips. Dedicated metal cutting saws operate at lower RPMs with proper guarding for safer, cleaner cuts.
