Our take on the Dewalt DCS512B 12V MAX XTREME Brushless 5-3/8" Cordless Circular Saw (Bare Tool)

The DeWalt DCS512B is a bare-tool 12V MAX XTREME brushless circular saw with a 5-3/8-inch blade. It cuts 1-3/4 inches deep at 90 degrees and 1-1/4 inches at 45, bevels 0 to 50 degrees, and runs at 3,600 rpm with an electric brake. At 4.9 lbs it is built for one-handed trim and sheet work rather than framing. The best new price is $89.99 at Walmart as of November 4, 2026, at the low end of its recent $89.99 to $98.45 range.

Questions and answers

Is the DCS512B worth it?
It is worth it if you already own DeWalt 12V MAX batteries and need a light saw for plywood and trim. If you need to cut 2x4s on edge or work all day in thick lumber, a 20V or 7-1/4-inch saw fits better.
What comes in the box?
The bare tool only: the saw and a rip guide. No battery, charger or blade case is included, so budget for a 12V MAX battery and charger if you do not have them.
How deep will it cut?
1-3/4 inches at 90 degrees and 1-1/4 inches at 45 degrees. That handles 1x stock and most plywood, but not a 2x4 stood on edge.
Does it use the same batteries as other DeWalt 12V tools?
Yes. It runs on DeWalt 12V MAX batteries, so it shares packs with the rest of the XTREME 12V line.
What blade size does it take?
A 5-3/8-inch blade with a 3/8-inch arbor. Keep a thin-kerf blade on hand for faster cuts in the 12V saw.
When is it cheapest?
The lowest recent price was $89.99 on November 5, 2026, and the high was $98.45 on November 4. The spread is narrow, so waiting rarely saves much.
Where is the Dewalt DCS512B 12V MAX XTREME Brushless 5-3/8" Cordless Circular Saw (Bare Tool) cheapest?
