The HMR-4 is the first Shop Hammer designed specifically for bicycle applications. Like all Park's tools, this one is built to last with a strong yet light fiberglass shaft and soft touch rubber grip. The dual-sided head features a steel striking surface on one side and a replaceable plastic surface (part #293) on the other.
Length: 13.5" (345mm). Steel striking face: 1-3/8" (35mm) diameter. Plastic face: 1-11/16" (43mm) diameter.
