2-Speed Hammer Drills

Bosch has three new 2-speed hammer drills that feature a new 17-tooth ratchet disc design that optimize drilling speed by maximizing impact energy at lower rpms. A 2-mode selector switch coverts the tools from hammer drill to rotation-only mode while the 2-speed drive-train enables users to choose between high speed and high torque. All drills feature an impact rate of 51000 bpm, integral overload clutch and a 360° torque control side handle. Models include the HD21-2, HD19-2 and the HD12-2D, which includes integrated dust collection capability.
