Chicago Pneumatic Air Hammer Kit: 0.401 in Shank Size, 2 5/8 in Stroke Lg, Round, Medium Duty

Kits include an air hammer and bits suited for different tasks. They ensure compatibility between components and eliminate the need to select a separate tool and bits. Air hammers use bits with 0.401" or 0.498" round shanks to handle most material removal and light chipping tasks. Sometimes called zipguns or chiseling hammers, they are lighter and more compact but less powerful than chipping hammers. They are commonly used to remove scale and slag, debur surfaces, and clean castings.
