Bosch GSR12V-300N 12V Max Brushless Drill vs Bosch 18V Brushless Drill/Driver Kit

Buy the 18V kit if you want one drill that covers most jobs out of the box. It has more torque (400 vs 300 in-lbs), a larger 1/2 in all-metal chuck, and comes with a battery, charger and bag. Buy the 12V GSR12V-300N if compact size and light weight matter most: it is shorter (6.0 vs 6.3 in head) and lighter (1.6 lb), which helps overhead and in tight cabinets. Owners of both lines praise the brushless motors and build; the 12V's catch is that batteries and charger are sold separately.

• Choose the Bosch 12V GSR12V-300N if you already own Bosch 12V batteries and want the smallest, lightest drill for overhead work, cabinets and tight spaces.
• Choose the Bosch 18V kit if you want a complete, ready-to-use drill with more torque, a 1/2 in all-metal chuck and batteries in the box.
