Proto J86034 Cold Chisel 3/4 Inch Stock

Product Description

The PROTO J86034 is a cold chisel designed for cutting, shaping, and breaking hardened metal, masonry, and fasteners. Cold chisels are driven by a hammer or mallet and are a standard hand tool in mechanical, plumbing, electrical, and HVAC service work. The J86034 features a 3/4 inch stock size, making it suitable for medium-duty chipping, bolt removal, and material separation tasks. It is built to withstand repeated impact without deforming, giving tradespeople a reliable striking tool for demanding jobsite conditions.

This cold chisel is used across residential and commercial service trades wherever cutting or breaking hard materials is required. Common applications include removing corroded fasteners, breaking mortar joints, cutting through conduit supports, and dressing metal edges. It is equally at home in mechanical rooms, on rough-in work, and in maintenance and repair scenarios where a powered cutting tool is not practical or safe.

Installation Notes

Cold chisels are installed by hand and driven with a ball-peen hammer or hand-drilling hammer. Always wear ANSI-rated eye protection when using a cold chisel, as metal fragments and debris are a common hazard. Inspect the chisel head before each use and remove any mushrooming with a grinder to prevent fragment ejection. Do not use a chisel with a damaged or cracked head.
