Overview

A replacement chain engineered to match the original specifications of DEWALT DCCS677Y1 / DCCS677B / DCCS677Z1 60V Chainsaw (1 Pcs) chainsaws. Chains wear down over time from regular use, and a fresh chain cuts faster and safer than a dull one.

Key specifications

  • Bar length: 20”

Compatibility

Fits DEWALT DCCS677Y1 / DCCS677B / DCCS677Z1 60V Chainsaw (1 Pcs) as a direct replacement for the factory chain. Check your owner’s manual or the existing chain’s markings to verify pitch, gauge, and drive link count before ordering.

Installation notes

Disconnect the spark plug wire or remove the battery before changing a chainsaw chain. Remove the bar cover, release bar tension, and take off the old chain. Place the new chain into the bar groove with the cutting teeth facing forward on top. Reinstall the cover, adjust chain tension until snug, and test by pulling the chain around the bar by hand. Re-check tension after a few minutes of use.

Common questions

Q: Will this 20 inch chain fit my DEWALT DCCS677B, or is it only for the DCCS677Y1 kit saw?

Yes, this chain fits the DEWALT DCCS677B, DCCS677Y1, and DCCS677Z1 because those are all versions of the same 60V 20-inch platform. The important match is the saw model and 20-inch bar size, not whether you bought the tool-only or kit version.

Q: I have a DCCS677Z1 with the original 20 inch bar—do I need to change the bar too, or can I just replace the chain?

If your original bar is still straight, the rails are not badly worn, and the groove is clean, you can usually replace just the chain. It’s a good idea to inspect the bar, clean the oil holes and groove, and confirm the new chain seats properly before tightening and setting chain tension.

Q: What’s the best way to install and maintain this chain on a DEWALT DCCS677 60V chainsaw?

When installing, make sure the cutting teeth on the top of the bar face forward, then tension the chain so it sits snugly but can still be pulled around the bar by hand with gloves on. After the first few cuts, recheck tension since a new chain can stretch slightly, and keep the bar oil reservoir filled to reduce wear on both the chain and bar.

Before you buy — how to verify fitment

  1. Find the bar stamp. Look on the side of your current guide bar for the pitch, gauge, and drive-link count.
  2. Match all three numbers. Pitch (3/8), gauge (.050"), and drive links (70DL) must all match.
  3. Check bar length. Measure cutting length from the tip to where the bar enters the saw body — this should match 20".
  4. 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.

Frequently asked questions

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.
