Proto J86A1/2S2 Cold Chisel 5/8 in Tip Steel Handle

Product Description

The PROTO J86A1/2S2 is a cold chisel designed for cutting, shaping, and breaking hardened materials including metal, masonry, and fasteners. Built with a 5/8 inch tip and a 7 inch overall length, it is sized for controlled hand-strike work in tight or confined areas. The steel handle provides solid energy transfer from hammer blows, and a full black oxide finish adds corrosion resistance for use in wet or demanding shop environments. Machinists, ironworkers, pipefitters, and general maintenance mechanics reach for this chisel when driving through rusted bolts, removing welds, or scoring metal stock. PROTO backs it with a manufacturer's limited lifetime warranty.

This cold chisel is suited for both shop and field use across industrial, commercial, and residential maintenance settings. It is a standard hand tool used wherever metal cutting or material removal is performed manually. Typical applications include removing seized fasteners, cutting keyways, splitting bolts, and chipping excess weld material. The compact 7 inch length makes it manageable for one-handed work with a ball-peen or cross-peen hammer. It fits naturally in a tradesperson's tool kit alongside punches, drifts, and other strike tools.

Installation Notes

Cold chisels are used by machinists, pipefitters, ironworkers, and maintenance technicians. Always wear ANSI-rated eye protection and appropriate gloves when striking. Inspect the chisel head for mushrooming before each use and dress the struck end as needed to prevent metal fragments from spalling. Do not strike with a hammer heavier than is appropriate for the chisel size.
