1/2 in. Dual Speed Hammer-Drill

Choose the hammer drill with power and speed controls for unmatched versatility. The adaptable ½” Dual-Speed Hammer Drill features an 8.5-amp motor that provides overload protection, even when drilling ¾” 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.
