Bosch GRW18V-120N Professional 18V 1/2″ Chuck Mud Mixer Drill – Tool Only

The Bosch GRW18V-120N is a cordless 18V mud mixer built for high-torque blending of mortars, muds, epoxies, and paints on busy jobsites. Its brushless motor and variable-speed trigger deliver controlled mixing up to 600 RPM (no-load), with soft start to reduce splatter when the paddle first enters the bucket. The tool runs forward and reverse for clearing paddles and dialing in mix direction, while KickBack Control helps protect against sudden reaction torque if a bind occurs in thick material. A multi-position handle lets users set a stable stance over tubs and buckets, and the 1/2″ keyed metal chuck clamps paddles securely for consistent torque transfer.

Designed for daily site use, this mixing drill includes a reinforced battery housing to help withstand accidental drops. It’s part of the AMPShare™ System, so the tool works with Bosch 18V batteries and a growing list of partner brands, simplifying fleet management and charging. At 6.8 lb and 14.4″ long, the GRW18V-120N balances power, access, and control—ideal for drywall compound, thinset, plaster, self-leveler, epoxy resin, and texture mixes where repeatable consistency matters.
