  • Our take on the Dewalt DWE4120

    The DeWalt DWE4120 is a corded 4.5-inch angle grinder with a 900 W motor that spins at up to 12,000 rpm. It is compact and light at about 6 lb, with a slim 4.875-inch body that fits one hand for cutting and light grinding. A two-position side handle and tool-free guard adjustment make it quicker to set up than older grinders. It suits home users and trades who want a simple, tough cutter rather than a variable-speed or brake-equipped model.

    • Tool-free guard and spindle lock speed up wheel changes
    • Two-position anti-vibration side handle included
    • Simple design with few parts to fail
    Cons

    • Single-speed trigger only, no lock-on for long sessions
    • Corded, so it needs mains power

    • PowerPraisedReviewers report the motor holds speed through cuts in rebar and plate.
    • Speed controlCriticisedBuyers miss variable speed for work on thin or delicate material.

    Questions and answers

    Is the DeWalt DWE4120 good for cutting metal?
    Yes. The 900 W motor and 12,000 rpm top speed handle rebar, bolts, studs and sheet metal well for a 4.5-inch grinder. It is a cutting and light-grinding tool, not a heavy surfacing machine.
    Does it have variable speed?
    No. The DWE4120 runs at a single speed up to 12,000 rpm. If you need slow speeds for polishing or thin material, look at a variable-speed model.
    What size discs does it take?
    It takes 4.5-inch (115 mm) discs with a 7/8-inch arbor. The guard is set for that size, so do not fit larger wheels.
    Does it come with a handle and guard?
    Yes. It ships with an anti-vibration side handle and a tool-free adjustable guard. Discs are not included.
    Is it safe to use one-handed?
    The slim body makes one-handed holding tempting, but grinders should be gripped with both hands where possible. Use the side handle and eye protection, and let the wheel stop before setting it down.
    Where is the Dewalt DWE4120 cheapest?
    At Tractor Supply Co, for $99.99, as of our latest check.
    Where can I buy the Dewalt DWE4120?
    2 stores we checked sell it, including Tractor Supply Co, Msc Industrial Supply.
