Proto J3S2 5 Piece Punch and Chisel Set

Product Description

The PROTO J3S2 is a five-piece punch and chisel set designed for professional use in maintenance, mechanical, and construction trades. The set includes center, pin, and starter punches along with cold chisels, covering the most common driving and cutting tasks on metal and hardened surfaces. All pieces feature a full black oxide finish that provides corrosion resistance and reduces light glare in the field. The hex shank design promotes secure bit retention and reduces rollaway on work surfaces. Punches range from 1/8 inch to 3/8 inch, and the chisel measures 5/8 inch, giving technicians a practical spread of sizes for a wide range of fastener, pin, and material work.

This set suits professionals who need a compact, organized punch and chisel kit for shop, fleet, or field use. The included tool roll keeps all five pieces secure and accessible, making it practical for service vans, tool bags, and bench storage. Machinists, millwrights, mechanics, pipefitters, and HVAC technicians will find this set useful for driving out roll pins, aligning parts, and cutting soft metal or frozen fasteners. The tool roll format supports organized tool accountability in professional environments.

Installation Notes

Punches and chisels should be struck only with an appropriate ball-peen or engineer's hammer of suitable weight. Inspect all pieces for mushrooming on the strike end before each use and dress or replace as needed to prevent chip hazard. Use appropriate eye protection per applicable safety standards when driving punches or chisels. Never use these tools on hardened steel that exceeds the rated hardness of the tool material.
