This replacement chainsaw chain is intended for select DeWalt 18-inch cordless saws, specifically the DeWalt DCCS672, DCCS672X1, DCCS672B, and DCCS600 models named on the original listing. If you need an 18 in. replacement chain for one of those saws, this is the fitment group to check first.

Will this chain fit your saw?

Measuring chain pitch, gauge and drive links

This chain is listed as compatible with these models:

  • DeWalt DCCS672
  • DeWalt DCCS672X1
  • DeWalt DCCS672B
  • DeWalt DCCS600

It is described in the source listing as:

  • 18 in. Replacement Chain for Dewalt DCCS672 / DCCS600 Chain Saw
  • 18” Chainsaw Chain Replacement for Dewalt DCCS672X1 Chainsaw
  • 18 Inch Replacement Chainsaw Chain for Dewalt DCCS672B Chainsaw
  • 18 Inch Chainsaw Replacement Chain for ‎Dewalt DCCS600 Chainsaw
  • 18” Chainsaw Chain Replacement for Dewalt DCCS672 / DCCS672X1 / DCCS672B / DCCS600 Chainsaw

Even when the model number matches, the safest way to confirm fitment is to compare the chain specs on your current bar or chain. A correct chainsaw chain match is based on four things:

  • Bar length: this page is for an 18-inch chain setup
  • Pitch: must match the drive sprocket and bar
  • Gauge: must match the bar groove width
  • Drive-link count: must match the exact bar/chain combination

If your saw is one of the listed DeWalt models and it is using the standard 18-inch bar setup, this replacement chain is the intended option. If your current bar has been swapped to a different length or aftermarket setup, verify the pitch, gauge, and drive-link count directly from the bar stamp or the old chain before ordering. That matters more than the saw’s model name alone.

A quick tip: many fitment mistakes happen because owners measure the full bar instead of the usable cutting length, or because they assume all 18-inch chains are interchangeable. They are not. Two 18-inch chains can differ in pitch, gauge, or drive-link count and still look very similar.

Replacing the chain

Fitting the chain onto the bar and sprocket

Before starting, remove the battery from your cordless saw and wear gloves. Chains are sharp even when dull enough to replace.

  1. Remove the battery and loosen the side cover to release chain tension.
  2. Take off the bar cover, then lift the old chain off the drive sprocket and away from the bar.
  3. Clean sawdust and oil buildup from the bar groove, sprocket area, and tensioning parts.
  4. Install the new chain around the sprocket and along the bar, making sure the cutting teeth face the correct direction on the top edge of the bar.
  5. Refit the side cover and adjust tension until the chain sits snugly against the bar but can still be pulled around by hand with a gloved hand.
  6. Fully tighten the cover, reinstall the battery, add bar-and-chain oil if needed, and check tension again after a short test run.

New chains can stretch slightly during the first few cuts, so recheck tension early.

Keeping it sharp

Sharpening a chainsaw chain cutter

A sharp chain cuts faster, puts less strain on the motor, and helps the saw oil properly through the cut.

  • Keep the chain properly tensioned. A loose chain wears faster and can derail; an overtight chain creates excess heat and bar wear.
  • Maintain bar-and-chain oil flow. Running dry is one of the fastest ways to dull a chain and damage the bar.
  • Touch up the cutters early instead of waiting until the chain is very dull. If the saw starts making fine dust instead of chips, pulling to one side, or requiring extra pressure, it is time to sharpen.

Also inspect the bar occasionally for burrs, uneven rail wear, or a plugged oil hole. A new chain performs best on a bar that is still in good condition.

FAQ

Will this fit every DeWalt 18-inch chainsaw?

No. This page is specifically for the DeWalt DCCS672, DCCS672X1, DCCS672B, and DCCS600 models listed above. Even among 18-inch saws, chain specs can vary, so confirm bar length, pitch, gauge, and drive-link count.

Can I replace just the chain if my saw is cutting poorly?

Often yes, but not always. A dull or damaged chain is a common cause of poor cutting, but you should also check chain tension, oiling, and bar condition. If the bar rails are heavily worn or the sprocket is damaged, replacing only the chain may not restore proper performance.
