DeWalt 60V Chainsaw File Size (Sharpening Chart)

For most DeWalt 60V chainsaws, the common factory chain uses a 5/32-inch (4.0 mm) round file, but check the chain installed on your saw before filing. A DCCS670 commonly has 3/8-inch low-profile pitch, .043-inch gauge, and 56 drive links; a DCCS672 commonly has .050-inch gauge and 62 links. Verify the chain maker’s filing angles and depth-gauge setting, too.

If your chain is making fine dust, cutting slowly, or pushing you to lean on the saw, stop and check its sharpness. The right file can restore the cutter edge; the wrong size can change its shape. The fastest safe route is to identify the chain itself, then match the file and settings to its manufacturer’s instructions.

DeWalt 60V chainsaw sharpening chart

This chart gives common identification starting points for two DeWalt 60V saw setups. It does not confirm what is installed today: a replacement bar or chain may differ from the original equipment. Check the chain markings or packaging, then confirm the maker’s file recommendation before sharpening.

A round file sharpens the curved cutting edge of each cutter. Pitch describes the spacing of the chain’s rivets; gauge is the thickness of the drive links that fit into the bar groove. Drive-link count is the number of links that travel around the bar. All three help identify a chain, but the chain maker’s markings or chart should guide the final file choice.

A 5/32-inch file is common for 3/8-inch low-profile chain, including the setups listed above. Still, don’t select a file from bar length or saw model alone. If the chain has been replaced, its specifications may not match the original setup.

For many chains, the typical top-plate filing angle is 30 degrees, and the depth-gauge setting is often .025 inch (0.635 mm). These are common references, not universal settings. Use the chain maker’s chart for the installed chain. Key takeaway: Start with the chain identification, then verify the file and sharpening settings.

Identify the chain before choosing a file

Chain identification means checking the markings and dimensions of the chain currently on the saw, rather than assuming it is the one supplied with the saw. This matters because replacement chains and bars can change the required match. Confirm pitch, gauge, and drive-link count before buying or filing.

Look for identification on the chain packaging, the chain itself, or the documentation for the replacement chain. Some chain makers mark cutters or drive links with identification codes. If you cannot find a clear marking, check the chain manufacturer’s chart or ask a qualified dealer to identify it.

Use this quick check:

• Find the chain maker and product information, if available.
• Confirm the pitch and gauge from the chain package or maker’s guide.
• Confirm the drive-link count when checking a replacement chain.
• Match the round-file diameter to the chain maker’s recommendation.
• Check the maker’s filing angle and depth-gauge instructions.

Do not use the bar length as a shortcut. A 16-inch or 18-inch bar does not, by itself, tell you which file size the chain needs. Nor does the 60V battery label identify the chain. Next step: If the chain’s identity is uncertain, pause rather than test a file by grinding on the cutters.

Set up safely before sharpening

Safe sharpening starts with an electrically isolated saw and a secured chain. Remove the battery before adjustment or hand filing, engage the chain brake as directed by the manual, and secure the bar and chain. Wear suitable eye protection and gloves, and follow the saw manual and worksite safety rules.

Before you begin, gather the verified round file, a file guide for the chain’s specified angle, and the correct depth-gauge tool. Chainsaw-rated leg protection, hearing protection, and protective footwear are important when operating the saw; use the protective equipment required by your work setting. Keep the work area stable and well lit.

Inspect the chain before filing. Do not try to sharpen out cracks, broken cutters, or damage that calls for chain replacement. If you find a loose or incorrectly fitted chain, correct the issue according to the saw manual before operation. A mismatched chain or poor tension can damage parts and cause serious injury.

Key takeaway: Remove the battery before working on the chain, and don’t file a chain that is damaged or unidentified.

File the cutters and check depth gauges

Sharpening means restoring each cutter’s edge while keeping the chain’s specified shape. Use the verified file size and a guide set to the chain maker’s angle. File each cutter consistently, then check the depth gauges with the correct tool and setting; a sharp edge alone does not complete chain maintenance.

With the battery removed and the chain secured, position the file in the cutter as directed by the chain maker. Use smooth strokes from the inside of the cutter toward the outside, keeping the guide aligned. Follow the maker’s specified angle; 30 degrees is a common reference, not a setting to assume for every chain.

Work through all cutters, keeping their lengths as even as you can. Uneven cutters can make the saw cut poorly or pull to one side. If the file seems to sit unusually high or low in the cutter, stop. Recheck the chain identification and file size rather than forcing the file or changing the angle to compensate.

After sharpening, use the chain maker’s depth-gauge tool and setting. A depth gauge controls how much wood a cutter can take. Many chains use a .025-inch setting, but the correct value depends on the chain. Do not lower the gauges by guesswork; follow the maker’s instructions and tool guidance.

Next step: Check every cutter and depth gauge, then inspect tension and lubrication before cutting.

Confirm chain fit, tension, and lubrication

A correctly sharpened chain still needs to fit the bar and run at the right tension. The chain’s pitch and gauge must match the bar and drive system, and tension must follow the saw manual. Check bar oil and use the specified bar-and-chain lubricant before returning the battery to the saw.

After sharpening, inspect that the chain sits correctly in the bar groove and around the sprocket. Adjust tension as the manual directs. A chain that is too loose can derail; an overly tight chain can add wear. Recheck tension after initial use and as the chain warms, following the manual.

Before cutting, verify the bar-oil level and that the chain receives lubrication. Use the prescribed bar-and-chain oil; do not substitute waste oil. Reinstall the battery only after adjustments are complete. Check brake operation and confirm the chain stops when you release the trigger, as directed by the manual.

The DeWalt 60V saw is battery-electric. It has no fuel mix ratio, engine idle speed, or engine RPM setting. Those specifications do not apply. Key takeaway: For this saw, focus on chain fit, tension, lubrication, and battery-safe handling.

Two chain-identification examples

These examples show how to use the chart without treating a model number as proof of what chain is installed. The listed setups are common starting points. A replacement chain may differ, so use the chain’s own markings and manufacturer instructions before selecting a file or fitting parts.

Example 1: DCCS670 with a common 16-inch setup. The starting reference is 3/8-inch low-profile pitch, .043-inch gauge, 56 drive links, and a commonly matched 5/32-inch (4.0 mm) round file. If the chain package confirms those specifications, check its maker’s chart for the filing angle and depth-gauge setting before sharpening.

Example 2: DCCS672 with a common 18-inch setup. The starting reference is 3/8-inch low-profile pitch, .050-inch gauge, 62 drive links, and a commonly matched 5/32-inch (4.0 mm) round file. If a replacement chain is installed, don’t assume these values still apply. Verify the installed chain’s identification.

In either example, a bar or chain change makes the installed parts the source to check. If the markings conflict with the common setup, stop and verify compatibility with the saw manual and chain documentation. Key takeaway: Use model information to narrow the search, not as a substitute for identification.

Frequently asked questions

These short answers cover the file size, angles, and checks that most often matter when sharpening a DeWalt 60V chainsaw. Use them as a quick reference, but follow the instructions for the specific chain and saw whenever they differ from a common setting.

What file size does a DeWalt 60V chainsaw use?
Many common DeWalt 60V chain setups use a 5/32-inch (4.0 mm) round file. Confirm the installed chain’s maker and recommendation before filing.

Is 5/32 inch the right file for the DCCS670?
It is a common match for the DCCS670’s commonly supplied 3/8-inch low-profile chain. Check the chain itself because replacement parts can differ.

What file size is listed for the common DCCS672 setup?
The common setup uses a 5/32-inch (4.0 mm) round file. Verify the installed chain and its manufacturer’s sharpening chart first.

What sharpening angle should I use?
Thirty degrees is a common top-plate filing angle. Use the angle specified by the maker of your installed chain.

What depth-gauge setting should I use?
Many chains use .025 inch (0.635 mm), but this is not universal. Check the chain maker’s instructions and use the correct depth-gauge tool.

Can I choose a file from the bar length?
No. Bar length alone does not identify the chain’s file size. Check the chain’s pitch, gauge, and manufacturer recommendation.

Does a battery chainsaw need a fuel mix ratio?
No. The DeWalt 60V chainsaw is battery-electric, so fuel mix and engine RPM settings do not apply.

What should I do if the file sits too high or too low?
Stop and verify the chain identification and file size. Do not force the file or keep sharpening with a doubtful match.

Can I sharpen a cracked or badly damaged chain?
Do not try to file out cracks or serious damage. Replace the chain when it is damaged or excessively worn, following manufacturer guidance.

What should I check before cutting again?
Check chain fit and tension, bar-oil level, brake operation, and that the chain stops when the trigger is released. Follow the saw manual.

Final check before heading out

For a quick, dependable setup, identify the installed chain first. The common DCCS670 and DCCS672 configurations listed here use a 5/32-inch round file, but that is a starting point, not a guarantee for a changed chain. Confirm the maker’s file size, filing angle, and depth-gauge setting. Then check fit, tension, and bar oil before cutting.
