9 Best Replacement Parts for the DeWalt DWS780 (November 2026)
The best DeWalt DWS780 miter saw replacement parts include the Generic Zero Clearance Insert for a custom kerf, the URYKEC N027988 Lower Guard for type-specific guard fit, and the Dewalt OEM N544383 Miter Saw Kerf Plate for an OEM kerf plate.
On this page (6 sections)
The best DeWalt DWS780 replacement parts are the ones that match your saw's type and the part number you need. For a lower guard, compare N027988 and your DWS780 type; for a kerf plate, belt or fence, verify the part number against the part you're replacing.
For a broader comparison, see replacement miter saw guards.
A DWS780 name alone may not settle fit. Some parts specify Type 1, Type 20 or other variants, so check the saw label and the number on the old part before you order.
The same fit check helps when choosing replacement miter saw guide rails.

Best replacement parts for the DWS780
The right choice starts with the part's job, then narrows by model type and part number. Match the saw label and old component before choosing a replacement.
Generic Zero Clearance Insert: Best for a custom kerf
- Names DWS780 compatibility
- Customizable blade opening
- Made in USA
A DWS780-compatible insert that can be customized to the blade opening. Check the insert fit and your saw setup before ordering.
Pros
- DWS780 is named as compatible
- Customizable opening
Cons
- The exact saw type is not specified
The Generic Zero Clearance Insert names the DWS780 along with the DHS780, DHS790, DWS779 and DWS782. Its stated dimensions are 17.25 x 3.37 x 0.5 in, so compare those with the opening and original insert on your saw.
The insert can be customized for the blade opening. That can support work close to the blade, but it also means the cut opening must suit your blade and setup.
The compatibility details do not identify a DWS780 type. If your saw is marked Type 1 or Type 20, confirm the fit before ordering.
Choose this insert if you want a customizable opening and its dimensions match your saw. For other styles, compare the best miter saw parts guide.
URYKEC N027988 Lower Guard: Best for type-specific guard fit
- Part number N027988
- Names DWS780 Type 1 and Type 20
- ABS material
A replacement lower guard with DWS780 Type 1 and Type 20 compatibility stated. Match your saw's type before ordering.
Pros
- Two DWS780 types are named
- Part number is stated
Cons
- Confirm the model type and part number
The URYKEC N027988 lower guard explicitly lists DWS780 Type 1 and Type 20. That type-specific detail makes it a useful candidate when replacing a damaged guard, provided your saw label and part number match.
The guard is made from ABS and measures 14 x 8 x 2.5 in. Check that space and the mounting points against your existing guard before installing a replacement.
A lower guard is a safety part. Don't use the saw if the guard is missing or does not move and cover the blade as intended; follow the saw manual or have a qualified repair person check it.
Dewalt OEM N544383 Miter Saw Kerf Plate: Best for an OEM kerf plate
- DEWALT OEM part N544383
- DWS780 compatibility
- Measures 17.25 x 3.25 x 0.5 in
This OEM kerf plate names the DWS780 as compatible. Compare the part number and dimensions with your existing plate.
Pros
- Genuine DEWALT replacement part
- DWS780 compatibility stated
Cons
- Check fit against your saw revision
The DEWALT OEM N544383 kerf plate is compatible with the DWS780 and measures 17.25 x 3.25 x 0.5 in. It is also listed for DWS779 and DHS790 variants.
Compare the part number and dimensions with the plate already on your saw, especially if the saw has been repaired before. A matching model name is helpful, but checking the specific part number reduces the chance of ordering a plate that does not fit your revision.
Choose this OEM plate when N544383 matches the part you need. If the kerf area is the issue, our Best Carbon Brushes For Miter Saw page covers a different common replacement part.
Rawolp N027988 Miter Saw Lower Guard Assy: Best for a replacement guard assembly
- Part number N027988
- Names DWS780 compatibility
- Also lists DWS779, DWS782, DHS716 and DHS790
This lower guard assembly names DWS780 compatibility and the N027988 part number. Compare the type and part number before replacing a safety part.
Pros
- DWS780 Type 1 and Type 20 listed
- Part number stated
Cons
- Verify the saw's type before ordering
The Rawolp N027988 lower guard assembly names the DWS780 Type 1 and Type 20 among its compatible models. It shares the N027988 part number with the URYKEC option, so compare construction, stated fit and the exact condition of your existing guard.
The compatibility list also includes DWS779, DWS782, DHS716 and DHS790. Confirm your saw's type before ordering, and inspect the old guard's attachment points so you can spot differences.
This is another candidate for a damaged lower guard, not a reason to use the saw with a faulty guard. Follow the DWS780 manual for replacement and adjustment.
Obida Belt 153555-00 For DeWalt Miter Saw: Best for a belt replacement
- Part number 153555-00
- Names DWS780 Type 1 and Type 20 variants
- Also lists DW706, DW708, DW716 and DW718
A replacement belt whose compatibility details name several DWS780 variants. Confirm your saw type and current belt part number first.
Pros
- Multiple DWS780 variants named
- Part number stated
Cons
- Belt size is not specified
The Obida belt uses part number 153555-00 and names several DWS780 variants, including Type 1 and Type 20. It also lists DW706, DW708, DW716 and DW718 models.
The belt size is not specified here. Before ordering, check the number on the old belt and your saw's complete model and type; don't rely only on the DWS780 name.
This pick suits a repair where 153555-00 is the confirmed belt number. Owners of other DeWalt models can compare our best DeWalt miter saw parts for the DW718 guide.
DEWALT OEM N600007 Blade Wrench for Miter: Best for blade changes
- DEWALT OEM part N600007
- Dual-ended wrench and key tip
- Names DWS780 compatibility
This OEM wrench is made for blade changes and guard or fence adjustments. It names the DWS780 among its compatible saws.
Pros
- OEM part number stated
- Two functions in one wrench
Cons
- Check compatibility if your saw has a different model or type
The DEWALT OEM N600007 wrench is made for blade changes and guard or fence adjustments, and its compatibility list includes the DWS780. Its dual-ended design combines a wrench head for arbor nuts with a key tip for adjustment screws.
This is a maintenance tool rather than a saw component. Choose it if the original wrench is missing or damaged, and confirm N600007 is the replacement number for your saw.
For blade changes, follow the instructions in the saw manual and disconnect power before servicing. If you need to secure stock during a cut, see how to use a DeWalt miter saw clamp.
Cncdesigns Zero Clearance Insert: Best for keeping spare inserts
- Set of 3 inserts
- Names DWS780 compatibility
- Made from MDF
A three-insert set for named DeWalt sliding miter saw models, including the DWS780. Each insert is for one blade and bevel setting.
Pros
- Three inserts in the set
- DWS780 compatibility stated
Cons
- An insert is limited to one blade and bevel setting
The Cncdesigns set includes 3 MDF zero-clearance inserts and names the DWS780 as compatible. Each insert measures 17.375 x 3.25 x 0.5 in.
The maker's description says each insert is calibrated for a specific saw, blade and bevel angle. That means a plate made for a straight 90-degree cut is not suitable for a different bevel setting; use the original insert or a matching plate for that setup.
Consider this set if spare inserts for different blade and bevel setups are useful. Check the intended use and fit before cutting into a new insert.
Leecraft DW-4 Zero-Clearance Insert for Dewalt Sliding: Best for a phenolic insert
- Phenolic material
- Names DWS780 compatibility
- Measures 17.375 x 3.25 x 0.375 in
A phenolic insert for several listed DeWalt sliding miter saws, including the DWS780. It is cut to match a particular blade and bevel setting.
Pros
- DWS780 compatibility stated
- Material and dimensions specified
Cons
- Choose the insert for the intended blade and bevel setting
The Leecraft DW-4 is a phenolic zero-clearance insert that names DWS780 compatibility. Its stated dimensions are 17.375 x 3.25 x 0.375 in, which differ from the other insert options here.
The maker describes cutting through the insert to create a kerf that matches the saw's blade and bevel setting. Keep that limitation in mind when choosing it, and compare the thickness with the insert your saw uses.
Pick it if you prefer a phenolic insert and the listed dimensions fit your saw. The DW705 replacement parts guide helps owners compare parts for an earlier DeWalt model.
Generic OEM N081824SV Replacement for DeWalt Miter: Best for a replacement fence
- Part number N081824SV
- Names DWS780 compatibility
- Measures 11 x 5.65 x 1.55 in
A replacement fence with DWS780 among the named models. Its compatibility list includes model numbers that differ from DWS780, so verify your saw label and part number.
Pros
- DWS780 is named
- Fence dimensions are stated
Cons
- Compatibility list includes other model number formats
The Generic N081824SV replacement fence names the DWS780 and measures 11 x 5.65 x 1.55 in. Its compatibility list also contains DWS7790, DWS7800 and DWS7820, so verify the precise model and fence part number before ordering.
The extra digits in those model names make this pick one to check carefully. Compare the number stamped on your saw and the old fence, then compare the stated dimensions with the part being replaced.
Choose it only when N081824SV and the fit details match your saw. If you're weighing repair against replacement, see how much a DeWalt miter saw costs.
How do you match DWS780 parts to your saw revision?
Match the complete model and type number on the saw label, then compare it with the part number and compatibility details for the replacement. If the part is marked with a number such as N027988 or N544383, compare that number with your old component.
The DWS780 Type 1 and Type 20 appear in compatibility details for the lower guards. Other parts name DWS780 variants without specifying both types, so contact the seller or a DeWalt service center when fit remains unclear.
For a guard, fence or other part that affects safe operation, don't modify the component to force a fit. Use the saw manual's repair guidance or seek qualified service.
Should you choose an OEM or aftermarket DWS780 part?
Choose based on the exact part number, model compatibility and whether OEM matters for your repair. The N544383 kerf plate and N600007 wrench are labeled DEWALT OEM, while the N027988 guards and 153555-00 belt are replacement options from other brands.
For inserts, material and setup matter as much as the model name. The picks here include plastic, MDF and phenolic options, and the CNC Designs and Leecraft descriptions limit each insert to a blade and bevel setup.
Compare dimensions and stated compatibility before deciding. A lower price alone cannot confirm a replacement will fit or work safely.
What should you check before ordering DeWalt DWS780 parts?
Check the saw's full model and type, the part number on the component, and any listed dimensions. For the belt, the compatibility details name several DWS780 variants but do not give a belt size, so matching the old number is especially useful.
For inserts, consider material, thickness and intended blade or bevel setup. For a guard or fence, compare attachment points and dimensions with the original part, then follow the saw manual during replacement.
For a guard that is broken, missing or binding, stop using the saw until it is repaired and the guard moves properly. Consult a qualified service person if the replacement fit or adjustment is uncertain.
Which DWS780 replacement part should you choose?
Choose the URYKEC or Rawolp N027988 guard if its type matches your DWS780, the N544383 plate if that number matches your kerf plate, and the 153555-00 belt only after confirming the old belt number. For a missing blade wrench, N600007 names DWS780 compatibility.
For inserts, pick by material, dimensions and blade setup; for a fence, verify N081824SV and the unusual model variants carefully. Compare the saw label with the part in hand before ordering any DeWalt DWS780 replacement parts.
