Proto's professional-grade 3/16-inch super-duty drive pin punch engineered for high-performance industrial maintenance and mechanical assembly. This tool is forged from premium S2 tool steel and specially heat-treated to provide a superior balance of extreme hardness at the tip and long-term impact resistance. Featuring a one-piece design for maximum energy transfer, the punch includes a modified parabolic striking end to reduce mushrooming and chipping, while the precision-ground reverse taper helps prevent binding in the workpiece. The shipping weight for this model is approximately 0.17 lbs.
