Covington's Cast Iron Cutter Cups are designed to provide maximum grinding surface contact while allowing for imperfections in the performed spheres. The soft cast iron material allows the grit to embed itself in the cutter cup, promoting a faster grind. These high quality cups are preferred and used by many lapidary and glass artists. This item is sold in a set of 3 pieces for use with three headed sphere machines.
