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

The Bosch GBM9-16 corded drill/mixer is built for high-torque material mixing and heavy-duty drilling applications. With a 9 Amp motor, variable speed from 0 to 700 RPM, forward and reverse operation, and a 5/8 in. keyed chuck, this Bosch mixer handles paint, plaster, mortar, epoxy resin, and other demanding materials with steady control.

The Bosch GBM9-16 is a heavy-duty corded drill/mixer designed for material mixing and large-hole drilling where torque, control, and durability matter. Bosch rates it with a 9 Amp motor, 0 to 700 no-load RPM, and forward and reverse operation, giving users the ability to match speed to the material or application. Higher speed works well for lower-viscosity materials such as paint or sealing compounds, while lower speed supports thicker materials such as plaster and similar mixes.

This model is built for repeated jobsite use with an all-ball-bearing motor, precision-cut steel gears, a heavy-duty 5/8 in. keyed chuck, and a magnesium front housing. Bosch also equips it with a 360° rotatable D-handle, soft-grip handle area, and an 8 ft rubber cord with a grounded plug. At 6.6 lb, it offers a practical balance of power and control for contractors, maintenance teams, and advanced users looking for a dependable corded mixer or drill/mixer.
