Are these two chains the same part?

Yes. Both are the DEWALT DWO1DT612, a 12-inch chain with 45 drive links for the 20V MAX DCCS620. Buy on price and return terms.

Which fits my DCCS620?

Both do. The DWO1DT612 is the stock chain for the 12-inch bar on the DCCS620, and the second listing also names the DCCS621B and DCCS620P1.

Is the low-kickback chain worth it over a standard chain?

Yes for most homeowners. Ramped depth gauges and ANSI low-kickback design reduce the chance of violent kickback, at a small cost in cutting speed versus a full-chisel chain.

How long does this chain last?

It depends on use and sharpening. Centri-Lube and hard-chromed cutters help, but expect to sharpen every few tanks of use and replace once cutters are worn or a link breaks.

Which is cheaper right now?

They are tied at $18.97 at Amazon as of November 4, 2026. Check the closeout listing for bulk pricing, but note it is final sale.

Can I return the closeout listing?

No. That listing is marked final sale and not eligible for return, so order the standard listing if you want the option to send it back.

DEWALT 12" Replacement Chain for Chainsaw vs DeWalt DWO1DT612 12-Inch Replacement Chainsaw Chain

These are the same chain: the DEWALT DWO1DT612, a 12-inch, 45-drive-link, 3/8-inch pitch, .043 gauge low-kickback chain for the 20V MAX DCCS620. Buy whichever listing is cheapest and returnable, since the part is identical. Both show $18.97 at Amazon as of November 4, 2026, so the price is a tie. One listing is flagged as a final-sale closeout, so check return terms before ordering there.
