This 20 inch replacement chain is made for the DEWALT DCCS677 60V chainsaw platform, including the DCCS677Y1, DCCS677B, and DCCS677Z1 versions listed for this product. If you need a 20” chainsaw chain replacement for one of those saws, this page is intended for that fitment group.
It is specifically described as a 20 in. replacement chain for DEWALT DCCS677 60V chain saw models. That makes it a model-specific replacement option rather than a universal chain.
Will this chain fit your saw?

This chain is listed as compatible with the following DEWALT chainsaw models:
- DEWALT DCCS677 60V Chain Saw
- DEWALT DCCS677Y1 Chainsaw
- DEWALT DCCS677B Chainsaw
- DEWALT DCCS677Z1 60V Chainsaw
- DEWALT DCCS677Y1 / DCCS677B / DCCS677Z1 60V Chainsaw
The first fit check is simple: confirm that your saw uses a 20” bar. This product is a 20 inch replacement chain, so it is intended for the 20 inch setup used on the compatible DCCS677 series saws.
After that, it is always smart to verify the full chain spec on your current bar or chain. Chainsaw chain fitment is determined by four things:
- Bar length: 20”
- Pitch
- Gauge
- Drive-link count
Even if two chains are both labeled 20 inch, they are not automatically interchangeable. The pitch, gauge, and number of drive links must also match your saw’s bar and sprocket setup. If your original chain is still available, compare its markings directly. You can also check the stamp or print on the guide bar, which often lists the required chain specification.
If your saw is one of the listed DEWALT models above and still uses its matching 20” bar setup, this chain is the correct replacement category for that saw. If your bar has been changed to a different length or different chain spec, confirm those details before ordering.
Replacing the chain

Replace chains carefully and only with the saw powered off.
- Remove the battery from your DEWALT chainsaw before doing any service.
- Loosen the side cover and release chain tension so the old chain can be lifted off the bar and drive sprocket.
- Fit the new chain around the sprocket and along the bar groove, making sure the cutting edges face in the correct forward direction on the top of the bar.
- Reinstall the side cover and adjust chain tension until the chain sits snugly in the bar groove but can still be pulled around by hand.
- Tighten the bar cover hardware securely, then recheck chain tension before use.
- After a short test run, stop the saw and check tension again, since a new chain can settle in quickly.
A chain that is too loose can derail. A chain that is too tight can wear the bar, sprocket, and motor system faster.
Keeping it sharp

A sharp chain cuts faster, more safely, and with less strain on your saw.
- Touch up the cutters regularly instead of waiting until the chain becomes very dull. Light, frequent sharpening is easier than trying to restore a heavily worn edge.
- Keep chain oil flowing and the bar groove clean. Poor lubrication creates heat, speeds up dulling, and increases stretch.
- Avoid contacting dirt, rocks, or metal. Even one ground strike can dull a chain very quickly.
If the saw starts making fine dust instead of chips, pulls to one side, or requires extra pressure to cut, it is usually time to sharpen the chain and inspect the bar.
FAQ
Does this chain fit every DEWALT 20” chainsaw?
No. This product is specifically listed for the DEWALT DCCS677, DCCS677Y1, DCCS677B, and DCCS677Z1 60V chainsaw models. A matching 20” length alone does not guarantee fit.
Can I use this chain if I replaced the original bar?
Maybe. If your replacement bar still uses the same 20” chain specifications required by your saw, it may fit. Check the bar length, pitch, gauge, and drive-link count on your current setup before ordering.
