Bosch PS31-2A 12V Drill Driver vs Bosch 18V Brushless Drill/Driver Kit

The Bosch 18V brushless kit is the stronger tool: 400 in-lbs of torque, 1,900 rpm, a 1/2-inch all-metal chuck and a brushless motor that runs longer per charge. The 12V PS31 is the lighter, smaller pick at 1.8 lb and 7 inches long, and it ships with two batteries plus a drill set. Owners of the 18V call it well-built and compact for its class; the 12V is a proven light-duty driver. Buy the 18V for sustained drilling and driving, the 12V for small jobs and tight spaces.

• Choose the Bosch PS31-2A if you want a light, short drill for cabinet work, assembly and overhead jobs, and you value two included batteries and a bit set.
• Choose the Bosch 18V brushless kit if you drill into wood, metal or masonry regularly and want more torque, a bigger chuck and longer runtime.
