How do I know this chain fits my saw?

Match three numbers: pitch, gauge, and drive-link count. All three must match the stamp on your current bar. If even one is off, the chain won't fit safely.

How do I measure pitch and gauge?

Pitch is the distance between any three consecutive rivets, divided by two. Gauge is the thickness of the drive links — measure with a caliper or check the bar stamp. Our guide covers both in detail.

How long does a replacement chain last?

With proper tension and occasional sharpening, an aftermarket chain lasts 3–5 cords of firewood or about 5 hours of active cutting — roughly the same as OEM.

Can I sharpen this chain or is it single-use?

Absolutely sharpen it. A quality replacement chain can be sharpened 3–5 times before the cutters are too short. Keep a round file matched to the cutter diameter.

Overview

This aftermarket 20-inch replacement chain is designed to fit select DeWalt chainsaw models. When the factory chain wears out, loses its edge after multiple sharpenings, or stretches past the tensioner’s range, this chain gets you back to cutting without waiting for a dealer order. It’s built to OEM dimensions for a direct fit.

Key specifications

Bar length: 20”
Type: Semi-chisel (aftermarket replacement)

Compatibility

This chain is designed as a direct replacement for select DeWalt chainsaws. Double-check the pitch, gauge, and drive-link count on your existing bar stamp before purchasing. These three measurements must all match for safe operation.

Installation notes

Kill the engine or remove the battery and let the saw cool. Loosen the bar cover and push the bar in to release chain tension. Remove the worn chain from the bar groove and sprocket. Fit the new chain into the groove, wrap it around the nose sprocket, and engage it on the drive sprocket. Pull the bar outward to tension, tighten the cover nuts, and dial in the tensioning screw until the chain sits snug against the bar rail with about 1/8-inch of pull.

Common questions

Q: Will this 20 inch replacement chain fit my DEWALT DCCS677, or do I need to match anything besides the bar length?

Yes, this chain is intended for the DEWALT DCCS677 with a 20 inch bar. Besides bar length, it’s always smart to confirm your original chain’s pitch, gauge, and drive link count match your saw’s bar specification before installation.

Q: Do I need any special steps to install this chain on my DCCS677?

Make sure the battery is removed first, then loosen the side cover, route the chain around the sprocket and along the 20 inch bar, and verify the cutters are facing the correct direction on the top side of the bar. After reassembly, set the chain tension so it sits snug against the bar but can still be pulled around by hand with a gloved hand.

Q: How often should I sharpen or maintain this replacement chain for the DEWALT DCCS677?

Sharpen it whenever you notice slower cutting, fine sawdust instead of chips, or if the saw starts pulling to one side. Keep the chain properly tensioned, make sure bar oil is flowing well, and inspect the cutters and drive links regularly, especially after cutting dirty or hardwood material.

Before you buy — how to verify fitment

Find the bar stamp. Look on the side of your current guide bar for the pitch, gauge, and drive-link count.
Match all three numbers. Pitch (3/8), gauge (.050"), and drive links (70DL) must all match.
Check bar length. Measure cutting length from the tip to where the bar enters the saw body — this should match 20".
Confirm your saw model against the compatibility list above. If your model isn't listed, the chain may still fit if pitch/gauge/DL match.
