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.

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.
