12-Volt Drill/Drivers, Images 9-12

Milwaukee's subcompact drill/driver (right) is much smaller than the author's 18-volt lithium-ion hammer-drill (left) and weighs about 3 1/2 pounds less.

Bosch and Ridgid have been competing for a while to produce the shortest subcompact. At the moment, it's Ridgid (far right) over Bosch (far left) by a hair.

The author mounted a new Irwin 3/4-inch Speedbor spade bit in each drill/driver, then counted the number of holes he could drill through 2-by Douglas fir per charge in high gear. He tested both of the batteries included with each tool.

To gauge the balance between maximum torque and overload protection, the author drilled 1/8-inch by 2 1/2-inch pilot holes in Douglas fir and then drove two 1/4-inch by 4 1/2-inch lag screws as deep as possible with each tool.
