Choose the hammer drill with power and speed controls for unmatched versatility. The adaptable 1/2 inch Dual-Speed Hammer Drill features an 8.5-amp motor that provides overload protection, even when drilling 3/4 inch holes in concrete. Choose controls in two ranges: 0 - 1,000 RPM / 0 - 16,000 BPM or 0 - 2,500 RPM / 0-40,000. It's versatile enough to drill in wood with flat boring bits, hole saws, auger bits and Selfeed bits - or drill in steel with twist bits and in concrete with percussion bits. The removable side handle helps you set the depth rod for preset hold drilling. The heavy-duty metal gear case withstands daily jobsite use, yet the drill's lightweight, balanced pistol-grip design reduces fatigue during a long work day. The 10-foot, QUIK-LOK cord and keyed chuck ensure hours of reliable, uninterrupted performance.
