  • Our take on the Dewalt DCG412B

    The DeWalt DCG412B is a bare-tool 20V MAX cordless angle grinder that takes 4.5-inch wheels and spins up to 8,000 rpm. It uses a slide switch, a tool-free guard and a two-position side handle, and it weighs about 6 lb with a battery. It suits people already on DeWalt's 20V battery platform who want cordless grinding and cutting for metalwork, and it is a step below DeWalt's FlexVolt grinders on power. Reviewers like the balance and the easy guard and wheel changes, but some find it heavy and say it drains batteries fast under load.

    Pros
    • Runs on the 20V MAX batteries many owners already have
    • Tool-free guard and spindle lock make wheel changes quick
    • Two-position side handle helps control in cuts
    • 8,000 rpm is enough for 4.5-inch cutoff and grinding wheels
    • Solid, well-balanced build for a cordless grinder
    Cons
    • Bare tool: no battery or charger included
    • Heavy at about 6 lb with a battery
    • Bogs down in heavy grinding compared with corded or FlexVolt models
    • Battery life is short under continuous load
    • Slide switch is not for everyone; some prefer a paddle

    Questions and answers

    Does the DCG412B come with a battery?
    No. It is a bare tool, so you need a DeWalt 20V MAX battery and charger separately.
    What size wheels does it take?
    It uses 4.5-inch (115 mm) wheels with an M14 spindle, the common size for cutoff and grinding discs.
    Is it good for cutting rebar and metal?
    Yes for light and medium cuts with a cutoff wheel. For long, continuous cutting, a corded grinder holds speed better.
    How does it compare with DeWalt's FlexVolt grinder?
    The FlexVolt model is more powerful and better suited to heavy grinding, but it is larger and needs FlexVolt batteries. The DCG412B is lighter and cheaper to get into if you already own 20V MAX packs.
    Does it have a paddle switch?
    No. It uses a slide switch on the body, so check that you are comfortable with that before buying.
    What is in the box?
    The grinder, a side handle and a wrench. Battery, charger and wheels are not included.
    Where is the Dewalt DCG412B cheapest?
    At NAPA, for $139.00, as of our latest check.
    Where can I buy the Dewalt DCG412B?
    3 stores we checked sell it, including NAPA, Tractor Supply Co, Lowe's.
