Klein Tools 66177 Cold Chisel 3/4 X 12 Inch

Product Description

The KLEIN TOOLS 66177 is a cold chisel designed for cutting, shaping, and breaking hardened materials such as masonry, concrete, metal fasteners, and welds. Built for heavy-duty trade use, this chisel measures 0.75 inches wide by 12 inches in length and weighs 1.05 pounds, giving it the mass and reach needed for demanding jobsite work. It is a hand-struck tool, driven by a hammer or maul, and is a standard item in the toolkit of electricians, plumbers, pipefitters, and general construction tradespeople who regularly work with masonry penetrations, rusted fasteners, or cast-iron components.

This cold chisel is suited for residential and commercial construction and maintenance applications. Common uses include cutting through brick and mortar for conduit or pipe penetrations, breaking out concrete anchors, splitting corroded nuts and bolts, and cleaning up welds or castings. The 12-inch length provides the working distance needed when striking in tight or recessed areas, reducing knuckle contact with the striking surface.

Key Features

• 12-inch overall length provides reach and working clearance in confined spaces
• 0.75-inch cutting width suited for masonry, metal, and fastener cutting tasks
• Hand-struck design compatible with hammers and mauls
• Compact 1.05-pound weight balances control with effective mass

Compatibility

Designed as a general-purpose hand-struck cold chisel for use in electrical, plumbing, and construction trade applications where masonry or metal cutting is required.

Installation Notes

Cold chisels are used by electricians, plumbers, and general contractors as hand-struck cutting tools. Always wear ANSI-rated eye protection when striking, as chips and fragments can be ejected during use. Inspect the chisel head before each use and dress any mushroomed material from the strike end with a grinder to reduce the risk of spalling. Never strike with a damaged or oversized hammer face relative to the chisel head diameter.
