Which chain fits the DeWalt DCCS620?

Both do. The DWO1DT612 is the OEM chain for the DCCS620, and the Proven Part 12-inch chain lists the DCCS620 as a fit with 45 drive links and 3/8" LP pitch.

Is the Proven Part chain as safe as the DeWalt?

The DeWalt chain is certified to the ANSI low-kickback standard and is marketed as reducing kickback. Proven Part does not state a low-kickback certification, so the DeWalt is the safer pick if kickback matters to you.

DeWalt claims Centri-lube reduces friction and extends chain life, and it is the OEM part. Proven Part gives no life claim. Expect the DeWalt to hold up longer, though sharpening habits matter more than brand.

Is the Proven Part chain worth it over the DeWalt?

At $5.99 at Amazon as of November 5, 2026, it is the cheaper way to keep a 12-inch saw running, and it fits more saws. If you want OEM spec and low-kickback certification, pay for the DeWalt.

Does the Proven Part chain fit other saws?

Yes. It lists the Milwaukee M18 Fuel, Kobalt 1224 and LCS1240, and Worx WG350 and WG380, plus the DeWalt DCCS620. Check your bar length, pitch and drive link count before buying.

How many chains do I get?

The DeWalt pack includes two DWO1DT612 chains. The Proven Part listing is a single chain.
