Bosch GSR18V-400B12 Drill/Driver Kit vs Milwaukee M18 Compact Brushless Drill/Driver

The Bosch GSR18V-400 is the stronger compact drill for most shoppers. It has more torque (400 in-lb vs Milwaukee's published compact figure), a faster top speed (1,900 vs 1,700 rpm), a shorter head length, and a much larger pool of owner ratings that consistently praise build quality and battery life. The Milwaukee M18 Compact is a solid, well-built tool and makes sense if you already own M18 batteries or want to stay in Milwaukee's platform. On paper the Bosch wins on specs and owner sentiment; the Milwaukee wins on platform loyalty.

  • Choose the Bosch GSR18V-400 if you want the most torque and speed in a short, light 18V drill and you are not already invested in another battery platform.
  • Choose the Milwaukee M18 Compact if you already own M18 batteries and chargers and want to add a drill without starting a new platform.

Questions and answers

Which is better for driving long screws?
The Bosch, on paper. Its 400 in-lb and 20+1 clutch give more headroom and finer control. The Milwaukee compact is capable but publishes less torque and fewer clutch settings.
Which lasts longer?
Both are brushless and should hold up for homeowner and trade use. Milwaukee backs its tools with a 5-year warranty; Bosch's coverage is shorter. Owner reports on the Bosch stress durability, but the Milwaukee warranty is the safer bet long term.
Is the Bosch worth stepping up to from the Milwaukee?
If you are not tied to M18 batteries, yes. The Bosch is shorter, faster and has more torque, and owners rate it highly. If you already own M18 packs, staying with Milwaukee avoids buying into a second platform.
Which is better for tight spaces?
The Bosch. Its 6.3 in head length is among the shortest in the 18V compact class, which helps between studs and inside cabinets.
Do both come as kits with a battery?
Yes. The Bosch kit includes one 2.0 Ah battery and charger. The Milwaukee is sold as a kit with battery and charger as well.
Which has better owner feedback?
The Bosch, by a wide margin in volume and score: 4.5 of 5 from 79 ratings versus 3.7 of 5 from 13 for the Milwaukee.
