Specially designed for hollow pins and springs, the precisely machined, self-centering guide ball tip keeps the drive shoulder in full, even contact with the pin wall, preventing the tip from slipping or deforming the wall.
A reverse taper ensures that the tip is slightly wider than the rest of the shaft, eliminating the possibility of it sticking in the pin hole.
Made from premium, high carbon steel, each punch is individually heat treated to harden and strengthen the tip while maintaining the soft temper of the striking end so it can absorb hammer blows without chipping.
