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: 3.Diameter 44mm (1 3/4 in)Additional Information:Hammer Type: Replacement Copper FaceFace Size (mm): 44Face Size (No.): 3Weight (g): 531Colour: Copper
