Bosch 18V Compact Brushless Drill/Driver vs Bosch GSR18V-755CB25 Drill/Driver Kit

The GSR18V-755CB25 is the stronger drill: 755 in-lbs of torque against 400, two 4.0 Ah CORE18V batteries against one 2.0 Ah, plus KickBack Control and a 25+1 clutch. The GSR18V-400B12 is the lighter, shorter tool at 6.3 inches of head length, which matters for overhead and cabinet work. Owners of both call them powerful and well built; the 755 draws a warning that Bosch's near-identical model numbers are easy to mix up, so check the model on the box.

• Choose the Bosch 18V Compact Brushless ½-Inch Drill/Driver Kit if you want a light, short drill for overhead work, furniture assembly and general home jobs, and one battery is enough.
• Choose the Bosch GSR18V-755CB25 if you drive large bits and lag screws, work in metal or masonry-adjacent tasks, or want two batteries and KickBack Control for heavier jobsite use.
