The Sullair MCH-3S Chipping Air Hammer is designed for rugged dependability in horizontal and overhead demolition and detail work, also perfect for industrial facilities and foundries. Designed for minimal air consumption with no additional lubrication requirements, the MCH-3S has virtually eliminated most high-wear parts from its design. The sleek 4-bolt backhead and “D” handle design reduce handle breakage and allow for a comfortable, sure grip, even with a gloved hand. Quick change screw-on ball retainer allows for fast steel changes by simply pulling the retainer back, inserting your steel and releasing to lock the steel in place.
