A tough job is no match for this powerful 7.5 A hammer drill. The two-finger, variable speed trigger (0 to 3000 rpm) has a convenient lock-on feature for increased control during driving and drilling. And the 48,000 bpm provides the power needed for tough applications. The heavy-duty 1/2 in keyed chuck accepts large diameter bits designed for woodworking and cutting and a side assist handle allows for controlled and accurate drilling in any task.
