A really well designed hammer drill.

Packing 8.5 amps of torque power, the Bosch 1/2" Dual Torque Hammer Drill will plough through any masonry that comes its way. Its compact and ergonomic design feels good in hand for less operator fatigue. A dual mode selector easily converts from rotation to hammer-drill mode. A two-speed gearbox (0-1,100/0-3,000 rpm, and 0-18,000/0-48,000 bpm) lets you adjust the speed and torque for a variety of applications. With a unique cord turret that pivots 35 degrees, you’ll have more freedom to move around. A rotating brush plate provides equal power in forward and reverse, and an integral slip clutch helps minimize wrist-torque. This kit includes 360-degree handle, depth gauge, and case.
