The Grace USA roll pin holder set has five punches that hold a roll pin in place so it can be started straight. They are made from high carbon 5160 steel, hardened through with a Bainite heat treat. The 1/16-inch punch is notched to clear AR-15/M16 rear sights, and the 3.5mm suits the breech block pin on SIG handguns.
