Two-Speed Hammer Drill

The Bosch HD21-2 Two-Speed Hammer Drill features outstanding power, with a 9.2 Amp motor that handles all masonry drilling applications. This hammer drill features a maximum of 51,000 BPM for productivity in concrete and masonry. The dual-mode selector easily converts from rotation-only to hammer-drill mode. Its rotating brush plate allows users to back out bound-up bits. It has two speed settings, one for high speed and one for high power. It has a 360° torque-control auxiliary handle that securely locks into place for great control in heavy-duty drilling operations. The handle has a built In. depth gauge for accuracy. This robust drill has a metal front housing for longer life, a heavy-duty keyed chuck for performance and an overload clutch for security against recoil.
