Product Overview
The Proto J471/4X3/32 Drive Pin Punch is a precision-engineered hand tool designed for durability and optimal performance in mechanical and industrial applications. Manufactured from specially heat-treated S2 steel, this 3/32-inch pin punch features a unique two-piece design that allows the tip to remain hard for longevity while being produced straight to prevent binding in the workpiece. The modified parabolic striking end significantly reduces the risk of mushrooming and chipping under heavy use.
To withstand harsh environments, the tool is coated with a rust-preventative black oxide finish, which extends its service life. The punch also features a polished identification panel on one of its flats, utilizing a high-contrast black inlay to clearly display the tool number and size for quick identification in the field.
