Our take on the DeWalt DCG412B 20V Max Lithium Ion 4 1/2" Cut-Off Grinder Tool, Bare Tool

The DeWalt DCG412B is a bare-tool 4-1/2 inch angle grinder that runs on DeWalt's 20V Max batteries. Its 6,500 RPM motor handles cutting and light grinding, and tool-free wheel changes and guard adjustment set it apart from grinders that need a wrench for every swap. It suits people already on the 20V Max platform who cut metal, rebar or tile and want one less cord. Against corded grinders it gives up some sustained power and runtime, and against brushless rivals it is simpler and older in design.

Questions and answers

Does the DCG412B come with a battery?
No. It is a bare tool: you get the grinder, a spanner wrench, a Type 1 cutting guard and a side handle. Batteries and a charger are sold separately.
Which batteries does it use?
It runs on DeWalt 20V Max lithium-ion packs. Any 20V Max battery you already own will fit.
What size wheels does it take?
It takes 4-1/2 inch wheels with a 5/8 inch arbor. Use wheels rated for at least 10,000 RPM.
Can it grind as well as cut?
It is set up as a cut-off tool with a Type 1 cutting guard. For grinding you need a Type 27 guard and wheel, and the single 6,500 RPM speed limits heavy grinding.
Is it worth it over a corded grinder?
If you already own 20V Max batteries and want cordless convenience, yes. If you do long, heavy grinding, a corded grinder gives more sustained power.
Does it have variable speed?
No. It runs at a single 6,500 RPM with a two-finger trigger and lock-off button.
