A tough job is no match for this powerful 7.5-amp hammer drill. The 2-finger, variable-speed trigger (0-3,000-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.
