Our take on the DeWalt DCS438B/DCB205 20V MAX Brushless 3 in. Cut-Off Tool Kit

The DeWalt DCS438B is a cordless 3 in. cut-off tool built on the 20V MAX battery platform. Its brushless motor spins a 3 in. wheel at up to 20,000 RPM, and the tool weighs about 2 lb without the battery. The kit includes a DCB205 5.0Ah battery. At $129.95 at eBay as of November 7, 2026, it sits at the low end of its recent range.

Questions and answers

Is the DCS438B worth it over a 4-1/2 in. angle grinder?
For light, one-handed cuts in thin metal, yes: it is smaller and easier to control. A grinder cuts deeper and handles heavier work.
What battery does the kit include?
The kit ships with a DCB205 20V MAX 5.0Ah Li-Ion battery. Any DeWalt 20V MAX pack will also run the tool.
What size wheels does it take?
It uses 3 in. cut-off wheels with a 3/8 in. arbor. Stock a few spares, since they wear quickly on hard steel.
How deep can it cut?
Depth is limited by the 3 in. wheel, so it suits bolts, rebar and sheet metal rather than thick stock. For deep cuts, use a larger grinder.
When is the price lowest?
At $129.95 at eBay as of November 7, 2026, it is at the low end of its recent range. Kit prices tend to dip around holiday sales.
Where is the DeWalt DCS438B/DCB205 20V MAX Brushless 3 in. Cut-Off Tool Kit cheapest?
