wilde tool ps 432.np/mp solid starter punch, 1/8 in tip, 4-1/2 in l, 5/16 in dia shank, high-carbon molybdenum steel

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 the entire length with a tempered striking end. Pin Punches have a reverse taper point which eliminates the punch from sticking in the work-place. Care should be taken that excessive heat is not obtained when re-sharpening. If the grinding temperature is not controlled, the hardness can be taken out of the immediate area. More importantly, a hard, brittle surface can be set which is very susceptible to fracture.
