Thor cylindrical copper faces are manufactured from 99.9% pure extruded electrolytic copper rod. These copper faces when fitted into a malleable iron head prevent damage to expensive machined sub components and assemblies. These Thor copper face heads are ideal where a heavy blow is required in a relatively small striking area. The faces are designed to wear and can be easily replaced.Size: 5.Diameter 70mm (2 1/2in)Additional Information:Hammer Type: Replacement Copper FaceFace Size (mm): 70Face Size (No.): 5Weight (g): 1246Colour: Copper
