12 Steel Dapping Punches Great for Metalsmiths & Metal Working. This is a new set of 12 steel dapping punches. Used for shaping, forming and chasing metal in dapping blocks. Made from tool steel and hardened to 50 Rc on both hit and work ends. Their unique tempering method leaves the shank of the punch with a mill hardness of 32 Rc to 36 Rc. This allows the handle to absorb the shock and prevent crystallization of the metal, which enhances the performance and life of the tool. Comes with wood stand. These punches measure approximately 1/2", 9/16", 19/32", 5/8", 11/16", 23/32", 3/4", 25/32", 13/16", 7/8", 15/16" and 1" (12.7, 14.28, 15.08, 15.87, 17.46, 18.25, 19.05, 19.84, 20.63, 22.22, 23.81 and 25.4 mm) We work hard to update our descriptions and pictures of our merchandise.
