Overview

This aftermarket chainsaw chain serves as a direct replacement for Dewalt 20V DCCS620B chainsaws. Available as a 3-pack, giving you a ready spare. Chains wear down over time from regular use, and a fresh chain cuts faster and safer than a dull one.

Key specifications

  • Bar length: 12”
  • Pitch: 3/8”
  • Gauge: .043”
  • Drive links: 45
  • Quantity: 3 chains per pack

Compatibility

Engineered for direct compatibility with Dewalt 20V DCCS620B. Always confirm your saw’s model number and bar length before ordering to ensure proper fit.

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 3-pack of 12-inch chains fit my DeWalt 20V DCCS620B, or do I need to match anything besides the bar length?

Yes, these chains are made for the DeWalt 20V DCCS620B and match the 12-inch bar length and 3/8 pitch used on that saw. It’s still a good idea to compare the markings on your original chain before installation, especially if the bar or chain has been replaced previously.

Q: I’m replacing the chain on my DCCS620B for the first time—do these install the same way as the original chain?

Yes, they install the same way as the factory-style chain on the DCCS620B. Make sure the cutting teeth on the top of the bar face forward, then set the chain tension so it sits snugly against the bar but can still be pulled around by hand with gloves on.

Q: How often should I sharpen or replace these 12-inch 3/8 chains if I’m mostly cutting small branches and firewood?

For light cutting, sharpen the chain whenever you notice slower cutting, fine sawdust instead of chips, or if the saw starts needing extra pressure. Keep the chain properly tensioned and the bar oil filled, and rotate through the 3-pack so you can swap in a sharp chain and maintain better cutting performance.

Compatibility

This part is verified to fit the following equipment. Always confirm the model number stamped on your machine before ordering.

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 (.043"), and drive links (45DL) must all match.
  3. Check bar length. Measure cutting length from the tip to where the bar enters the saw body — this should match 12".
  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.
