Wilde Tool Solid (Starter) Punch 5/32″ PS532 PS 532 - 5/32″ x 5″ SOLID PUNCH. All Wilde punches and chisels are forged from high-carbon molybdenum tool steel and individually heat-treated to make them the toughest striking tools on the market. Wilde punches and chisels are hardened with a tempered striking end. Chisel cutting edges are sharpened and re-sharpened to give the keenest points available. Pin Punches have a reverse taper point which prevents the punch from sticking in the workplace. Chisels are designed to be re-sharpened once they become dull. Care should be taken that excessive heat is not obtained when re-sharpening. The hardness can be removed from the immediate area if the grinding temperature is not controlled. More importantly, a hard, brittle surface can be set which is very susceptible to fracture.Always wear safety goggles when using punches and chisels.
