DEWALT DCCS677 20-Inch Chainsaw Chain (2-Pack)

DEWALT DCCS677 20-Inch Chainsaw Chain Fitment Guide

This 2-pack of 20-inch replacement chains is designed for DEWALT 60V chainsaw models DCCS677Y1, DCCS677B, and DCCS677Z1. If you use one of those saws and want to keep cutting performance close to original, this set is a straightforward way to swap in a fresh chain when the old one is dull, damaged, or stretched beyond useful adjustment.

A new chain can help your saw cut faster, track better, and reduce the extra pressure that often comes from trying to force a worn chain through wood.

Will this chain fit your saw?

This chain set is intended for the following DEWALT chainsaw models:

• DEWALT DCCS677Y1
• DEWALT DCCS677B
• DEWALT DCCS677Z1

The easiest first check is bar length: this is a 20-inch chain, so your saw should be using a 20-inch guide bar. For the models listed above, that is the intended fitment.

To confirm fitment more carefully, match the chain specifications already on your saw or in your owner’s manual:

• Bar length: 20 inches
• Pitch: match the existing chain
• Gauge: match the existing chain
• Drive-link count: match the existing chain exactly

Pitch, gauge, and drive-link count all need to agree with the bar and sprocket system. Even if a chain is labeled 20-inch, it will not fit correctly unless those other specs match too. If your old chain is still available, the most reliable approach is to compare its markings and count directly before ordering. If the printing is worn off, check the bar stamp or the saw documentation for the original chain specification.

If you own a different DEWALT saw not listed here, do not assume this chain will fit just because it uses a 20-inch bar. Fitment should be confirmed by the full chain spec, not bar length alone.

Replacing the chain

Use basic chainsaw safety practices and follow your saw’s manual. In general, replacement looks like this:

1. Power the saw off and remove the battery before doing any service.
2. Loosen and remove the side cover, then back off chain tension so the old chain can come off the bar and drive sprocket.
3. Install the new chain around the sprocket and along the guide bar, making sure the cutting teeth face the correct direction on the top edge of the bar.
4. Seat the chain properly in the bar groove and around the sprocket, then reinstall the side cover.
5. Adjust chain tension until the chain sits snugly against the bar but can still be pulled by hand around the bar while wearing gloves.
6. Recheck tension after a few cuts, since a new chain may settle in quickly.

A chain that is too loose can derail. Too tight can cause excess wear on the bar, sprocket, and motor system.

Keeping it sharp

A sharp chain makes a big difference in how the DCCS677 cuts. A few habits help extend chain life:

• Keep chain oil topped off and make sure the bar is oiling properly. Poor lubrication causes fast wear and heat buildup.
• Touch up the cutters regularly instead of waiting until the chain is very dull. Light, consistent sharpening is easier than heavy restoration.
• Avoid dirt, rocks, and embedded debris in logs. Even one contact with the ground can dull a chain quickly.

It is also smart to inspect the bar groove and clean out packed sawdust during chain changes. Good bar condition helps a new chain perform properly.

FAQ

Will this chain fit all DEWALT 20-inch chainsaws?

No. This 2-pack is specifically listed for DEWALT DCCS677Y1, DCCS677B, and DCCS677Z1. A 20-inch bar alone does not guarantee compatibility.

Why buy a 2-pack instead of one chain?

Having a spare chain ready is useful for routine maintenance. You can swap in a sharp chain immediately and sharpen the other later, which helps reduce downtime and keeps your saw cutting like new.
