The adaptable 1/2 in Dual-Speed Hammer Drill features an 8.5 A motor that provides overload protection, even when drilling 3/4 in holes in concrete. Choose controls in two ranges: 0-1000 rpm/0-16000 bpm or 0-2500 rpm/0-40000. 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.
