Proto J471/4X1/16 Drive Pin Punch
The Proto J471/4X1/16 is a high-strength 1/16-inch drive pin punch engineered for heavy-duty durability in industrial, mechanical, and maintenance applications. Constructed from specially heat-treated S2 steel, this punch utilizes a two-piece design that allows the tip to remain extremely hard and straight, preventing binding during operation. It also features a modified parabolic striking end that significantly reduces mushrooming and chipping, maximizing operator safety and tool longevity. A black oxide finish provides excellent corrosion resistance.
Key Features
- S2 Steel Construction: Specially heat-treated material delivers superior strength and extended operational life.
- Two-Piece Design: Ensures a precision-straight, hardened tip to resist binding in tight tolerances.
- Parabolic Striking End: Modified profile effectively mitigates mushrooming and chipping under heavy impact.
- Black Oxide Finish: Protects the tool from rust and corrosion in harsh working environments.
- Clear Identification: A polished identification panel on one flat is marked with the punch number and size in a black inlay for rapid tool selection.
