Cold Chisel 7/8 in x 18 in

The Mayhew 10219 is a heavy-duty cold chisel built for metalworking tasks. Its steel body measures 18 in overall and features a 7/8 in angled blade tip hardened to 55 to 57 HRC. The black oxide finish provides corrosion resistance for workshop durability.

Suited for metal shaping and cutting

This tool suits mechanics and fabricators who need to cut or shape softer metals using a hammer strike. The oversized end style adds strength for repeated impact. Buyers who need a handled chisel or a non-sparking tool for hazardous environments should look elsewhere.

Blade tip hardness 55 to 57 HRC

The decisive specification is the blade tip hardness rated between 55 and 57 HRC. This heat treatment level determines whether the edge holds up when driven into softer metals without mushrooming or chipping prematurely.
