Will this chain fit my DeWalt DCCS620?

Yes. It is the 12-inch, 45-link chain made for the DCCS620 20V MAX saw. It will not fit other 12-inch saws with a different link count.

Is $9.30 a good price for this chain?

Yes. At $9.30 at eBay as of November 4, 2026, it is at the low end of its recent range across the five stores that list it new. Buying a spare at this price is reasonable.

Do I need tools to install it?

You need a wrench for the bar nuts and a file or sharpener for upkeep; neither is included. Installation is straightforward but takes adult assembly.

Is this a low-kickback chain?

Yes. It meets ANSI standards for low-kickback chain, which reduces the chance of the saw kicking back during cutting.

How do I make it last longer?

Keep the bar oil reservoir filled, check tension before each use, and retension a new chain after the first few cuts. The Centri-lube design helps only when oil is present.

How often should I replace the chain?

Replace it when sharpening no longer restores a clean cut, when cutters are badly worn, or when the chain keeps jumping the bar. Keep a spare on hand so a dull chain does not stop the job.
