Two-Speed Hammer Drill

HD18-2 HD18-2

Product Description


The Bosch HD18-2 Two-Speed Hammer Drill features a muscular 8.5-AMP motor that handles all masonry drilling applications, delivering a max of 51,000 BPM for muscle and durability. The tool's drilling capacities range from 3/4-In. for masonry applications to 1-1/2-In. for wood. The HD18-2 features a torque-control auxiliary handle, which locks into place; the handle has a built-in depth gauge. The dual-mode selector easily converts from rotation-only to hammer-drill mode. A rotating brush plate allows users to easily back out bound-up bits. It has two speed settings, one for high speed and one for high torque. Because of its heavy-duty three-jaw 1/2-In. chuck, the tool has a high clamping force that that prevents drill bits from slipping. This robust drill has a metal front housing for longer life, a pistol-grip handle with soft-grip design and an integral slip clutch for security against recoil.
