SPEEDAIRE Air-Powered Hammer 21AC13 Air 3inch L 1740 bpm 0.401in Shank Size, 3 1/2in Stroke Lg 1pc

Air hammers use bits with 0.401" or 0.498" round shanks to handle most material removal and light chipping tasks. Sometimes called zip guns or chiseling hammers, they are generally lighter and more compact but less powerful than chipping hammers. They are commonly used to remove scale and slag, debur surfaces, and clean castings. Their pistol-grip design sets the barrel at a right angle to the grip, so users can control the pressure applied to the bit and hold the tool steady in a range of positions on vertical and horizontal surfaces. They have a trigger switch to activate the tool.
