Individual Dapping CuttersAll PEPETOOLS precision made, highly polished dapping punches and cutters are made from tool steel and hardened to 50 RC on both hit and work ends. PEPETOOLS unique tempering method leaves the shank of the punch at a mill hardness of 32 RC 36 RC. This allows the handle to absorb the shock and prevent crystallization of the metal. Our unique hardening technique enhances the performance and life of the tool.
