Bosch HD21-2 Speed Hammer Drill
Boschs contestant comes in as the second most powerful, at 9.2 amps and packs some really nice features. This unit has a patented rotating brush plate (the part that provides the hammering action) which works in both directions, allowing you the same hammering action when trying to back out a stuck bit. There is also an integral slip clutch to minimize torque reaction to your hands and arms. This is also a two-speed, reversible drill, allowing for high-torque or high-speed operations, and reversing for removing fasteners. I've given the number one place to the DeWalt unit because of power, but this drill has a lot going for it. Id be hard pressed to decide between the two.
