The DongCheng HD102301 25 x 18 x 300mm Cold Chisel is built for severe industrial metal demolition, shearing heavy structural fasteners, and rigorous mechanical maintenance. Manufactured from premium 45# carbon steel, it is drop-forged and thoroughly heat-treated to withstand repeated sledgehammer strikes without fracturing or edge crumbling.
With an expansive 25mm cutting edge and an 18mm heavy-duty shank spanning 300mm in length, it provides extended reach and high kinetic energy transfer into struck metals. The tool features an ergonomic rubberized grip equipped with a large protective hand guard that isolates the user's hand from impact recoil and accidental misstrikes. Packaged with an individual plastic hanger for pegboard mounting.
