Drive Pin Punch Set

High quality round shank carbon steel punches. Special tempering process prevents head from fracturing. Induction hardening ensures consistent hardness through the length of the punch. Two piece construction with a 3 3/4 inch long pin; allows the pin to have a separate hardness from the body which prevents “peening” and also ensures complete straightness over such a long length. Punches have clean and well cut knurling for a positive non- slip grip.
