How to select the right starter punch size?
Select a starter punch with a tip diameter slightly smaller than the pin you are driving. For the PROTO J505/16S2, the 1/8 in tip suits small pins. Ensure the shank width (5/16 in) fits your hammer face. Always use safety glasses and a hammer with a striking face larger than the punch head.
