These air-powered tools remove dents, smooth out ridges, and shape sheet metal more efficiently than manual hammers. Fast, controlled blows allow you to create a smooth, even finish. Hammers include attachments with different radius sizes to form a variety of shapes and finishes. They have a sturdy metal frame to keep the hammer in place and a foot pedal to control the speed, leaving both hands free to guide the workpiece. An automatic oiler keeps the machine running smoothly.
