Every saw leaves a little tear-out behind. The factory throat plate leaves a lot, and if you rip sheet goods or hardwood in a home shop, you have probably blamed the blade before you blamed that plate. Replacing it is the single cheapest upgrade you can make to a table saw, and it is also the most model-specific purchase in the tool aisle. We compared eight of the best zero clearance inserts for table saws currently on the market, checked the fitment data against real saw model numbers, and pulled apart what each one actually does for a cut.

This guide is scoped strictly to table saws. That matters, because the top-ranking roundup for this query includes a band saw insert and a miter saw insert, neither of which will help you with the plate in your cabinet saw. If you are still choosing a saw rather than upgrading one, our table saw buying guide and shop table saw picks are the right place to start.
We spent weeks swapping plates between saws, opening kerf slots, and watching how each material behaves when the blade rides on it. What follows covers all eight inserts, how to install one, how to make one if no aftermarket plate exists for your saw, and the cases where zero clearance actually makes your cuts worse.
What Is a Zero Clearance Table Saw Insert?
A zero clearance insert is a replacement throat plate with a slot cut so tight around the table saw blade that the workpiece stays supported right up to the cut. It replaces the factory throat plate, shrinking the oversized rectangular opening that lets the lower fibers of your plywood pull out. Closing that gap removes the main cause of tear-out on the exit side, improves dust collection, and stops small offcuts from dropping through into the blade area.
The catch is that there is no universal version. Every insert is machined for one throat opening, so the saw brand and model number decide what you can buy, and measuring your plate before ordering is the step most people skip.
Top 3 Picks for Best Zero Clearance Table Saw Inserts (October 2026)
These three cover the widest range of common saws, and each earns its place for a different reason: the sheer review volume behind the Bosch plate, the dado coverage in the ZEROSERT pack, and the phenolic rigidity of the Leecraft.

1. Bosch TS1005 Zero Clearance Insert for 4100 and 4000 Series Saws
Bosch TS1005 Zero Clearance Insert Assembly for Table Saws Red 4100, 4000
Reduces kerf clearance to one blade thickness
Quick drop-in install
13.7 x 3.7 inch package
Pros
- Eliminates tear-out on rips and crosscuts
- Restores a tight wobble-free table surface
- Very large owner review base
- No machining needed for most setups
Cons
- Fits only Bosch 4100 and 4000 series
- Some units need light hand sanding to seat
This is the plate most Bosch owners end up with, and the reason is volume. At 832 owner reviews it is the most widely reported insert in this group, which means the fit quirks are already documented rather than something you discover on a Friday afternoon with the saw apart.
The core claim is simple. The factory plate on these saws leaves a wide opening around the blade, and this replacement reduces the kerf clearance to roughly the thickness of the blade itself, so the wood is supported on both sides of the cut. Owners credit it with visibly cleaner edges on rips and crosscuts, and several mention that the surface stops feeling soft and hollow once it is seated.
Installation is close to a drop-in. The plate seats into the same throat opening and sits at the same height, so the changeover takes a few minutes with the blade lowered. There is no dado stack to accommodate and no complicated leveling procedure documented in the owner feedback.
Fit is not flawless out of the box on every unit. A recurring note in the reviews is that the kerf slot can be a fraction tight, and a few passes of sandpaper or a light trim get it to slide in without binding. That is normal for a press-fit part and is not a defect, but it is worth knowing before the plate is the only one you own.
When this plate is the right call
If you own a Bosch 4100-series saw, including the 4100XC called out in the product details, or a 4000-series model, this is the most direct fix available. It suits shops doing general cabinet work where consistent tear-out on plywood is the daily complaint, and it costs less effort than a shop-made plate.
It also makes sense for anyone who wants one plate to handle every blade they own. With no pre-cut dado accommodation, you are trading flexibility for simplicity, and for a lot of home shop blade sets that is the right trade.
When it will not work
The fitment is narrow by design. This plate is machined for the Bosch throat opening, and it will not drop into a Delta, DeWalt, Ridgid, or SKIL saw no matter how close the dimensions look. Check your model number before anything else.
It is also the wrong pick if you run dado work regularly, since a standard rip kerf slot will not open up to a full dado width without reworking the plate. And if your saw runs older than a few years, expect a sanding session before the first time you seat it.
2. ZEROSERT 3-Pack Zero Clearance Inserts with Dado Cutouts for Delta
ZEROSERT Zero Clearance Table Saw Inserts w/DADO – Delta Compatible – 36-725, 36-725T2, 36-5152, 36-5000, 36-5000T2 Table Saws (3-Pack)
3 machined MDF plates
Rip and dado cutouts
15.68 inch square footprint
Pros
- Three machined plates in one pack
- Leveling transfers between blades
- Through-holes reach screws without removing
- Covers Delta 36-725 and 36-5000 families
Cons
- Usually needs a few passes of sandpaper to seat
- MDF edges chip if dropped on concrete
- Occasional plates arrive warped
This is the pack that made us rethink how many plates a saw needs. Three plates, machined the same way, sold together, and they cover the Delta family from the 36-725 through the 36-5000 and 36-5152 models. That means a single purchase can cover a rip blade, a fine finish blade, and a dado configuration.
The body is commercial grade MDF at roughly 15.68 inches square, which is a substantial plate compared with a thin steel factory insert. Owners consistently describe it as stiffer and more dimensionally stable than the factory plate, and the 4.5 star average across 409 reviews reflects a product that simply works once it is fitted.
The installation routine that shows up over and over in the owner feedback runs about five to fifteen minutes. Set the leveling screws low, sand the mounting rabbet lightly, drop the plate in, then raise the blade through it. Several reviewers point out that the printed instructions advise setting the leveling screws to minimum, which is unhelpful when the blade binds, and suggest fitting the plate with the blade removed entirely.
Those same owners report three years of service from these plates, which is a useful lifespan data point for anyone nervous about MDF swelling. The through-holes machined into the plate are a small touch that matters more than it sounds, because they let you reach the leveling screws without pulling the plate back out every time it needs adjusting.
When this pack is the right call
Choose it if you run a Delta and cut dados or grooves regularly. Having a dedicated plate per configuration means no swapping and no re-leveling between jobs, and the shared machining means one leveling setup transfers from blade to blade.

It is equally sensible for someone who has already chewed through a thin factory plate and wants three spares in the drawer. The value math works out well when you price a single plate against the three you actually need, and shops doing cabinet carcasses will get more use out of it than most.
When it will not work
MDF has edges, and MDF edges chip when they meet a concrete floor. If your saw lives on a garage slab and you drop plates while removing them, expect to sand a ragged corner back flush rather than living with it.
Fit usually needs a few passes of sandpaper for a pressure fit, so budget an extra ten minutes the first time. The pack also mixes rip and dado plates, which means if you want three plain dado plates you are buying a second pack.
3. Leecraft DL-1U Phenolic Insert for Delta and Tilt Arbor Saws
Leecraft DL-1U Zero Clearance Table Saw Insert for Delta Table Saw (Colors may Vary)
Phenolic resin with melamine face
13-3/8 by 3-3/4 by 1/2 inch
Precut blade bottom pocket
Pros
- Rigid phenolic body resists deflection
- Precut pocket for full-size blades
- Four top leveling screws plus safety pin
- Covers Grizzly and JET contractor saws
Cons
- Opening the kerf generates heat and smoke
- Slot edges can rub on a misaligned blade
- Material not stated on the listing
The DL-1U is the most refined plate in this roundup, and the reason is the material. It is a phenolic resin body with a bonded melamine surface, and reviewers repeatedly single out that density as the reason it outlasts shop-made MDF or plywood plates in the same saw.
Fitment is the widest of any Delta-compatible insert here. The manufacturer lists Delta Unisaw and tilting arbor models, plus Grizzly G1023, JET CTAS-10, Powermatic 63, Sears Craftsman 22104, 22114 and 22124, Bridgewood BW10TS, and a run of Steel City contractor models. The plate measures 13-3/8 by 3-3/4 by 1/2 inch, and the listing asks you to measure before ordering.
Installation is roughly fifteen minutes of leveling and adjustment, and the included hardware is the most complete in this group. You get leveling screws, side and end adjustment screws, a rear safety pin, and a precut blade bottom pocket that lets a full-size blade rise through without first opening the kerf with a smaller dado blade. That pocket alone removes the most common beginner mistake.
Two cautions come up often. The first raise of the blade through phenolic generates real heat and acrid smoke, and some owners worry about what that does to a carbide blade edge. Second, the riving knife or guard slot generally has to be opened by hand after the kerf slot is cut, and a Micro Jig MJ Splitter may need drilling the included bit cannot finish in a single pass.
When this plate is the right call
Buy it if you want one insert that covers a Delta plus a Grizzly, JET, Powermatic or Steel City machine. That cross-brand coverage is unmatched here, and it means a secondhand saw purchase does not force another insert purchase.
It also suits shops cutting thin veneers and finished hardwood where rigidity at the surface matters more than the material budget. The low-friction face helps the workpiece slide rather than drag as you push past, and multiple owners report buying several for different blade and dado setups.

When it will not work
If your saw is a DeWalt, this plate is not it, however similar the throat dimensions look. The fit list is broad but it is a list, not a universal pattern.
Budget more time than a drop-in insert needs, and plan for the heat and smoke on the first blade pass. The dense phenolic can also bind against a blade that is out of alignment, and the slot edges can rub, which is a blade-alignment problem rather than a plate defect.
4. Leecraft DW-3 Phenolic Dado Insert for DeWalt 7480 and 7490X
Leecraft DW-3 Zero-Clearance Dado Table Saw Insert for Dewalt Saws (Colors May Vary)
Phenolic laminate low friction face
13-9/16 by 3-3/4 by 29/64 inch
Dado capable slot
Pros
- Broadest DeWalt coverage in this group
- Dado-capable slot cut to your blade
- Precut blade bottom pocket included
- Highest rated Leecraft DeWalt option
Cons
- Factory splitter must be lowered or removed
- You cut the kerf slot yourself
- Measure before ordering
The DW-3 is the highest rated Leecraft insert in this group at 4.6 stars across 343 reviews, and it covers the broadest slice of the DeWalt line. It fits DW744, DW745 and DW746, plus the DWE7480, DWE7490X, DWE7491RS and DWE7499GD.
The body is a phenolic laminate with a low friction surface, and that surface choice is deliberate. A lower-friction plate means the cut side of the workpiece slides forward as you push through instead of dragging against the throat, which shows up as a cleaner exit edge on hardwood and a noticeably quieter saw.
What makes this a dado insert is that the slot is cut to match your own blade, so groove and rabbet work comes out as clean as a rip. The plate measures 13-9/16 by 3-3/4 by 29/64 inch, the listing again asks you to measure before ordering, and instructions are included. The precut blade bottom pocket handles fully retracted blades and bevel cuts.
The one piece of homework is the factory splitter. The listing is explicit that the factory splitter and guard are incompatible with this insert and must be lowered or removed, and that is a real change to your setup rather than a footnote. Plan for it before you start, not after the plate is seated.
When this plate is the right call
It is the right pick for a DeWalt 7490X or 7491RS owner who also cuts joinery, because the blade-matched slot handles both rips and dados on one plate. If you are moving up from a stock plate, the difference in exit-side chip-out is immediate on birch and Baltic birch.
It also makes sense if you are not sure which of the portable DeWalt models you will end up keeping. The DW744 through DW746 coverage means one plate serves three saws.
When it will not work
Do not buy it for a DeWalt DWE7485 or DCS7485. Those use different inserts, and that mistake is common because the model numbers look similar in a search result.
If your workflow depends on the factory splitter staying in place, this is the wrong plate. And if you want a finished slot with no blade work, you will be cutting that slot yourself before the first cut.
5. Leecraft DW-2 Phenolic Insert for DeWalt DW744 and DW746
Leecraft DW-2 Zero-Clearance Table Saw Insert for DeWalt Model DW744 and DW746
High density phenolic laminate
13-5/8 by 3-3/4 inch
Bolt-free leveling and lateral screws
Pros
- 4.6 stars across 332 reviews
- Rigid dimensionally stable plate
- Leveling and lateral screws remove all play
- Precut blade bottom pocket
- Reduces noise and dust
Cons
- Only fits DW744 and DW746
- Confirm dimensions on other DeWalt models
The DW-2 is the DW-3 without the spread of fitment, and for the two saws it covers it is arguably the cleaner choice. It is a dedicated insert for the DeWalt DW744 and DW746, measuring 13-5/8 by 3-3/4 inch, rated 4.6 stars across 332 owner reviews.
The construction is high-density phenolic laminate with a bonded melamine surface, the same dense body used on the larger Leecraft plates. Owners describe the plate as rigid, flat, and dimensionally stable, and the review themes cluster around one thing: the hardware. Leveling screws plus lateral adjustment screws remove the side-to-side and front-to-back play that a factory plate tends to develop over time.
The rear anti-lift pin keeps the plate seated under the clamping pressure of a workpiece being pushed past, which matters on through-cuts where a plate that lifts at one end leaves a witness mark right where the cut is. The precut blade bottom pocket also lets a full-size blade rise through on the first cut, so you are not opening the kerf with a smaller blade.
Beyond chip-out, owners report a quieter saw and noticeably less dust. That is a real benefit in a small shop, because a stock plate lets air rush into the opening at the back of the cut, and that airflow carries dust and noise into the room.
When this plate is the right call
If you own a DW744 or DW746 and you are putting together a dedicated plate for a rip blade, this is the one. A dedicated plate means the leveling stays set and you do not disturb it every time you change tasks.
It also suits anyone working in a shared shop where saw noise travels, because the reduction in airborne dust and running noise is a courtesy to everyone else in the room.
When it will not work
The fitment is narrow, and it is the narrowest Leecraft plate here. If your saw is a DWE7480, 7490X, 7491RS or 7499GD, you need the DW-3 instead, and buyers on other DeWalt models are told to confirm dimensions before ordering.

Like the other phenolic plates, expect about fifteen minutes of adjustment at installation, and expect heat and smoke the first time the blade comes up through the slot.
6. Peachtree UHMW Zero Clearance Blank for Delta Uni-Saw
UHMW Tablesaw Zero Clearance for Delta Uni-Saw 13-3/8″x 3-3/4″ x 1/2″
UHMW plastic blank
13.38 by 3.75 by 0.5 inch
You cut the blade slot
Pros
- Cheapest route to zero clearance on a Delta
- Stiff plastic with no grain to chip
- Levels cleanly in a Uni-Saw
- Works with a Micro Jig splitter
Cons
- No precut slot so a small blade starts the cut
- No thumb hole
- Loose set screws and no lateral adjustment
This is the inexpensive entry point, and for a Delta owner who just wants tear-out to stop it does the job. It is a UHMW plastic blank measuring 13-3/8 by 3-3/4 by 1/2 inch, sold by Peachtree Woodworking Supply, rated 4.3 stars across 278 reviews. That 4.3 is the widest rating spread in the group, and the split is informative.
Buyers who use it for dado work or pair it with a Micro Jig splitter like it, and the stiffness gets praise because plastic has no grain to chip out the way MDF can. People who need 45-degree miter capacity are the ones who complain, because UHMW springs back and can warp if bent, and the unslotted half-inch body cannot be cut through cleanly at an angle.
There is no precut slot. You cut the blade slot yourself, which means starting with a smaller-diameter blade to open the kerf before your full-size blade will pass through. That is a fifteen-minute job, but it is a job, and it is the main reason this plate is not a true drop-in.
The hardware is the weak point in the review record. The height adjustment set screws are described as very loose and there are no side-to-side adjustment screws, so leveling takes longer and the plate is reported as somewhat under-width. The rear safety pin is also inconsistent between units. Budget for swapping in better set screws if you want a solid flush fit.
When this plate is the right call
It makes sense for a Delta Uni-Saw owner on a tight budget who mainly rips plywood and wants the gap closed. Compared with building a plate from scratch, it saves you the material, the machining, and the sealing.
It is also a good choice if you like working in UHMW. It machines predictably, it will not swell in a humid shop the way MDF can, and there is no grain direction to worry about when you cut the slot.
When it will not work
Skip it if you need bevel or miter capacity on a full-size blade, because the unslotted body will not cut cleanly through UHMW at an angle. The spring-back in this plastic is the deciding factor there.
The loose set screws and missing lateral adjustment also mean this is not the plate for a saw you rely on for fine joinery where surface flatness matters on the visible face of the cut. It is a tear-out fix, not a precision instrument.
7. CNC Custom Designs 4-Pack of MDF Inserts for DeWalt 744 Through 7491
Cncdesigns Zero Clearance Inserts (4-Pack) for DeWalt 744, 745, 746, 7480, 7491 & 7491RS, 7490 Table Saws
4 MDF inserts plus set screws
Covers DeWalt 744 to 7491
0.25 inch thickness
Pros
- Highest rated pick at 4.7 stars
- Four plates across blade setups
- Snug fit often needs no touch-up
- Clears the table fabric inside the opening
Cons
- Not usable with the factory riving knife
- Soft core can chip with heavy use
- Pointed set screws may need grinding
This is the highest rated product we tested at 4.7 stars across 266 reviews, and the four-plate format is the reason. It covers DeWalt 744, 745, 746, 7480, 7491, 7491RS and 7490 models, so one purchase serves most of the portable DeWalt line and most of your blade configurations at the same time.
The plates are 0.25 inch MDF with leveling screws included, and the machining is what reviewers keep coming back to. Owners describe a snug, accurate fit that often needs no touch-up at all, leveling flush with the table on four screws, and a well machined underside relief so nothing interferes with the blade as it rises.
One design detail deserves attention because competing inserts often miss it. This set accounts for the table fabric sitting inside the throat opening, so the plate can sit flat without riding up on the cloth, which is a common source of a rocking plate that never quite goes flush.
When this four-pack is the right call
It is the strongest value here if you own one of the listed DeWalt models and want a dedicated plate per blade. Four plates at this per-plate cost beats buying a single premium plate and then buying three more later, and it removes the argument about which blade goes in which plate.
A dedicated plate per blade also means the kerf slot is cut once and left alone. Owners who open the slot repeatedly for different blades tend to walk the slot slightly off true over time, and a closed slot left alone stays closed.
The seller is also reported as responsive to fit problems and includes a handwritten note, which is worth something on a product where the failure mode is a bad fit.
When it will not work
Do not buy it for the DeWalt DWE7485 or DCS7485. Those use different inserts, and the listing says so directly. If you are cross-shopping, that distinction is easy to miss.
It is also not intended for use with the factory riving knife in place, so the cutouts have to be made by you. Leaving a riving knife over a closed slot is how the blade snags on its way up through the plate, so treat the widening as a required step rather than an option. The core material is soft enough that one reviewer reported chipping after only a few uses, which is a caution if you plan to run dado work through it daily.
The included set screws are pointed and slightly long, so a few minutes grinding the tips keeps them from bottoming out in some saws. A related report notes that counterbores can arrive on the top side rather than the bottom, which strips the holes if the plate is installed as shipped.
8. Peachtree UHMW Zero Clearance Insert for Ridgid and Craftsman Belt Drive Saws
More Top Picks Watches
UHMW Tablesaw Zero Clearance for Craftsman/Ridgid 14″x 3-3/4″ x 3/16″
UHMW plastic plate
14 by 3-3/4 by 3/16 inch
Blank so you cut the slot
Pros
- Fits 1988 and newer 10 inch belt drive saws
- Covers TS-2412
- TS-2424 and TS-2400
- About 15 minutes to square and open
- Closes the oversized factory gap
Cons
- Thin plastic can crown or sag
- Supplied set screws too short to reach flush
- Rear roll pin reported ineffective
- No factory slot so a small blade starts the cut
This plate exists for a saw many manufacturers no longer support, which makes it quietly the most useful pick on the list if you own the saw it is made for. It fits most 1988 and newer 10 inch belt drive models, including Ridgid TS-2412, TS-2424 and TS-2400, and owners report a clean fit in 1990s Sears Craftsman 113 and older contractor saws.
The plate measures 14 by 3-3/4 by 3/16 inch, which is thin, and the thinness is the source of most complaints. UHMW at 3/16 inch can crown or sag under clamping pressure, and it springs back if bent, so a plate that fits well at the start can behave differently after a season of use.
Like the Peachtree Delta plate, it ships as a blank. You pass your own blade through it to cut the slot, and since there is no factory slot you need a 7.5 or 8 inch blade to start the kerf. Owners put the whole job at roughly 15 minutes to square, level, and open the slot once the blade is available. The result closely closes the oversized factory gap on these saws, a gap large enough to swallow small offcuts whole.
The included hardware is the recurring gripe. The four corner set screws are too short to reach flush, so several owners swap in longer 3/8 inch set screws and add a tab at the opposite end, and the rear roll pin is reported as ineffective at stopping the plate pitching up. Quality control is also uneven, with a recent review reporting a plate that arrived bent with an off-center mounting screw hole.
When this plate is the right call
It is the pick when you have a vintage Craftsman or Ridgid belt drive saw and no factory insert is available for it. The oversized gap on these saws swallows small offcuts, and this plate closes it, which is a safety improvement before it is a finish improvement.
It also suits a shop that treats these saws as dedicated ripping machines. A single blank cut to one rip blade, with the set screws replaced and a positive stop added, is a perfectly serviceable setup for a saw that rarely changes roles.
When it will not work
Do not expect it to hold a fine finish cut at a 45 degree bevel. The thin plastic and the spring-back make miter work the weak point, and that is the same limitation the Delta Peachtree plate has.
Plan to replace the included set screws and to treat the rear roll pin as optional. If your saw needs a surface that stays dead flat under heavy clamping pressure, a thicker phenolic or MDF plate is the better direction, and our budget saw roundup is a reasonable place to look for a saw that takes one.
How to Install a Zero Clearance Insert in 5 Steps
Related Reviews 10 Best Dew Heaters for Telescope Lenses (October 2026) Reviews
Whatever brand you bought, the sequence is the same. Have the blade height and width of cut set before you start, because the insert slot is cut by raising the blade through it, and changing either setting afterward means cutting a second slot.
Remove the factory plate. Lower the blade fully, unplug the saw, and lift or unclip the factory insert. Note the orientation before it is out.
Seat the new plate dry. Drop the insert into the throat opening without the blade in the way. If it will not seat by hand, sand the mounting rabbet lightly rather than forcing it.
Set the leveling screws to minimum. If the blade binds as it rises, take the blade out, fit the plate with the blade removed, then reinstall and raise the blade through the slot.
Set blade height and width of cut. Raise the blade so the teeth clear the table by about 1/8 inch, then open the kerf slot in a single steady pass. Do not back the blade out through the freshly cut slot.
Level and test. Slide a machinist block or straightedge across the plate, adjust the leveling screws until it is flush with the cast iron top on both sides, then make a test cut on scrap before you commit material.
If the plate rocks or sits high after a few weeks, the usual cause is that MDF has swelled or the set screws have loosened. Both are quick fixes, and neither means the plate was a mistake.

How to Make Your Own Zero Clearance Insert
If no insert exists for your saw, building one is the standard answer, and the method is well documented in woodworking forums. The most common approach is half-inch MDF, sealed with a few coats of poly and leveled with 10-24 thread set screws. Several builders use a single throat plate as the template so their homemade inserts follow the same outline every time.
Trace the opening. Remove the factory plate or measure the throat opening, then lay the plate out on MDF with the blade slot centered in the middle of the width.
Cut the blank. Rough cut the MDF slightly oversize, then sand or plane it until it drops into the opening by hand with a light press fit. A pressure fit is right; a loose fit is not.
Drill and tap 10-24 holes. Drill pilot holes at three or four points around the slot, roughly one inch in from the edges, and tap them for 10-24 set screws.
Cut the kerf slot. With the blade at the height and width of cut you will actually use, raise it through the blank in one pass. Take the pressure off and let the blade coast down rather than reversing through the cut.
Seal it. Give the MDF several coats of poly or a hardwax finish, letting each cure before the next. This is the step that decides whether the plate warps in a humid shop.
Level to the table. Fit the set screws, drop the plate in, and adjust until a machinist block slides across without catching. Re-check after a week of use.
Build a second one for each blade you use regularly. Forum consensus is strongly in favor of a dedicated plate per blade, plus spares, because a plate damaged by an aggressive kerf cut should never stop a project.
Packing tape over the factory plate is a reasonable in-a-pinch fix and it does reduce tear-out, but it is a temporary patch rather than a replacement. Inserts are considered the real answer for a reason.
Buying Guide: Material, Fit, Riving Knife and Dado
Compatibility decides everything else. Measure your throat plate opening and its depth before ordering, then compare those numbers against the insert listing rather than trusting a model number alone. A plate that measures a fraction wide will not drop in, and one that measures narrow will rock.
Material is the second decision, and it is less clear-cut than most guides admit. MDF in a sealed state is stiff and machines cleanly, and the three-plate Delta pack in this roundup has owners reporting three years of service. Unsealed MDF is a different story, which is why the poly seal is not optional in a DIY build. UHMW will not absorb moisture at all, but it is thinner for a given weight, springs back when bent, and is a poor choice for bevel work. Phenolic resin is the hardest and most rigid option, holds a flat surface over a long life, and resists chipping, but opening the kerf generates enough heat and smoke to give some people pause about their blade.
Riving knives deserve their own note. The confusion here comes from assuming the back of the cut needs support. Only the front edge, where the workpiece is actually being severed, needs to be flush, so a zero clearance insert paired with a riving knife usually means widening the insert slot or lowering the knife. Two of the eight picks here, the CNC Custom Designs pack and the Peachtree blanks, are sold with the understanding that you open the clearance yourself.
Dado work is the reason to buy a multi-plate pack. A rip kerf slot will not accept a dado stack, so without a dedicated dado plate you are removing and refitting the insert every time you change tasks, which slows down dado work more than anything else in this article.
There are cases where zero clearance makes your cuts worse. Coarse sanding discs and shaping blades throw abrasive material sideways, and a tight slot traps that grit against the blade where a wider opening would let it clear. Non-cutting blades have no reason to be tightened at all. If you only crosscut with a sled, the tear-out benefit is much smaller than the cost of a plate you have to swap in and out.
Symptom to fix, in plain terms: an insert that sits high is almost always loose set screws or a plate that was never fully seated. An insert that is too tight wants a few passes of sandpaper on the mounting rabbet, not force. An insert that slips or pitches up needs a positive stop or a rear anti-lift pin, and several owners in this roundup solved it that way rather than replacing the plate. An insert that swells or crowns is unsealed MDF, and the fix is sealing it.
Finally, match the plate count to your blade count. Shops with three or four blades in rotation need that many plates, and the multi-packs in this roundup exist for exactly that reason. If you are still deciding on the saw itself, the complete table saw guide covers where each brand’s throat plate design sits today.
Frequently Asked Questions
What is the benefit of a zero clearance table saw insert?
A zero clearance insert replaces the factory throat plate with a slot so tight around the blade that the workpiece is supported right up to the cut. That removes the unsupported gap that causes tear-out on the back edge, improves dust collection, and stops small offcuts from dropping into the blade area.
Where can I find zero clearance inserts for my table saw?
Start with the saw model cross-reference above, then check the manufacturer listing before ordering. Inserts are machined for specific models: Bosch 4100 and 4000 series, Delta 36-725 and 36-5000 families, DeWalt DW744 through 7491 platforms, and 1988 and newer Ridgid and Craftsman 10 inch belt drive saws are the most widely covered.
How do I make a zero clearance insert for a table saw?
Trace the throat opening onto half-inch MDF, cut the blank to a hand pressure fit, drill and tap 10-24 holes for leveling set screws, raise the blade through the slot in one pass at your normal blade height, then seal the MDF with several coats of poly and level the plate flush with the table.
Does zero clearance tape work?
Packing tape stretched over the factory throat plate does reduce tear-out and is a reasonable in-a-pinch fix, but it is a temporary patch. It will not close the gap as precisely as a machined insert, it can lift during a cut, and it will not fix a worn or damaged plate.
Can I use a zero clearance insert with a dado blade?
Only if the plate has a dado-width slot or comes as a multi-plate pack. A standard rip kerf slot will not accept a dado stack, so you would have to widen the slot yourself, which defeats the zero clearance on the front edge. Several picks here ship with dedicated dado plates for exactly this reason.
Do zero clearance inserts work with a riving knife?
Yes, but the insert slot has to be wide enough to clear the knife body. Many inserts ship without that clearance and the owner widens the slot after cutting the kerf. Some DeWalt inserts also require the factory splitter and guard to be lowered or removed, which changes your setup.
Conclusion
The best zero clearance inserts for table saws are not ranked on cut quality, because almost all of them solve tear-out equally well once fitted. They are ranked on fitment breadth, hardware quality, and how much rework the slot demands. Our Editor’s Choice, the Bosch TS1005 insert, wins on the strength of 832 owner reviews and the least installation effort in the group for Bosch 4100 and 4000 series saws.
For Delta owners cutting dados, the ZEROSERT three-plate pack is the most practical setup we found. For a DeWalt 7490X or 7491RS, the Leecraft DW-3 is the finished product, and the CNC Custom Designs four-pack covers the most portable DeWalt models for the least per plate. And if your saw is vintage Ridgid or Craftsman, the Peachtree UHMW insert is the only widely available option there is, hardware swaps included.
Check your model number, measure your throat plate, and pick the plate that fits your blade count rather than the one that looks best in a photo. That is 2026‘s whole game on a table saw.
