The Bosch GRW 140 Professional is a powerful 1400W corded paint and construction material mixer designed for mixing large volumes of paint, plaster, cement, mortar and other building materials. It combines a high-performance motor with a two-speed gearbox, electronic speed control and an ergonomic wheel-shaped handle for comfortable operation during extended mixing tasks.

The GRW 140 provides two selectable speed ranges: 200–480 RPM in first gear and 300–750 RPM in second gear. The lower-speed range provides higher torque for heavier mixing materials, while the higher-speed range is useful for lighter and more fluid materials. Bosch specifies rated torque of approximately 10.2Nm in first gear and 6.7Nm in second gear.

Its M14 tool holder accepts compatible mixer baskets, and Bosch specifies a maximum mixer-basket diameter of 140mm. The tool also incorporates soft start, speed preselection, constant electronic control and restart protection, helping provide controlled and consistent mixing performance.

The ergonomic wheel-shaped handle is designed to reduce strain during prolonged use. Bosch also provides a carbon-brush lifespan indicator, helping the user know when brush replacement is required.
