Bosch GBM9-16 Corded Heavy Duty 5/8″ Mixing Drill 120V 9A

The Bosch GBM9-16 is a purpose-built mixing drill designed to handle everything from lightweight paint and sealants to heavier materials like mortar, plaster, and epoxy resin. Its 9-amp motor delivers high torque with variable speed control (0–700 RPM) in forward or reverse, giving crews the ability to dial in the right speed for the material’s viscosity. Higher RPM suits low-viscosity liquids such as paint and primers, while lower RPM provides the torque needed for thick compounds and bag mixes. A 360° rotatable D-handle lets the user set a comfortable stance around buckets or mixing tubs, and the soft-grip main handle with a two-finger trigger provides steady control over long pulls.

Built for jobsite durability, the GBM9-16 uses an all-ball-bearing motor and precision-cut steel gears for efficient torque transfer. A heavy-duty 5/8″ keyed chuck accepts a wide range of mixing paddles and large drill bits (up to 1/2″ in steel), while the magnesium front housing keeps weight down without sacrificing strength. An extra-long 8 ft rubber cord with a grounded plug adds reach around the shop or site. At 6.6 lb and 14″ long, this corded mixing drill balances power, control, and portability for consistent, repeatable results in daily use.
