Ideal for machine, small equipment, and gun service and repairs, the TEKTON 5/64 in. Roll Pin Punch smoothly drives out or inserts hollow pins or springs without deforming them. The guide ball tip self centers for perfect alignment in the pin, keeping the drive shoulder in full, even contact with pin wall to prevent slipping or damage. Precisely machined to a reverse taper, the tip is just a bit wider than the rest of the shaft. This eliminates the possibility of it sticking in the pin hole. Made from premium, high carbon steel, each punch is individually heat treated, creating a strong, hardened tip while keeping the soft temper of the striking end, allowing it to absorb hammer blows without chipping.
