Which chain fits the DEWALT DCCS620?

Both do. The DEWALT DWO1DT612 is the OEM chain for the 12-inch bar on the DCCS620. The NEO-TEC S45 is a 3/8-inch LP, .050-gauge, 45-drive-link chain that lists the DCCS620 as a fit.

Is the NEO-TEC three-pack worth it over one DEWALT chain?

Yes if you cut often. Three NEO-TEC chains cost $17.98 at Home Depot as of November 4, 2026, about the same as one DEWALT chain at $18.97 at Amazon as of November 4, 2026.

Hard to say from specs alone. DEWALT uses Centri-lube oil channels and NEO-TEC uses LubriTec with a chrome outer layer. Both depend on bar oil and sharpening habits.

Are both low kickback?

Yes. DEWALT states ANSI low-kickback compliance, and NEO-TEC states it meets the ANSI B175.1-2012 kickback requirement.

Can I use the NEO-TEC chain on other saws?

Only if the saw takes 3/8-inch low-profile pitch, .050 gauge and 45 drive links on a 12-inch bar. Check your bar's stamped specs first.

Do I need tools to swap the chain?

Yes. You need a scrench or bar wrench to loosen the bar nuts and adjust tension. DEWALT notes tools are not included with its chain.
