Sumitomo Electric Carbide says its SumiMill Goalmill milling cutter accurately finishes cast iron. The cutter is said to provide quality surface finishes through the use of tangentially mounted inserts accompanied by easily adjustable, axially mounted wiper inserts. Each insert offers eight indexes when using single-handed cutters. Four indexes can be used on the periphery pockets, and flipping the insert on its side enables four more indexes in the finishing cartridge. A total of 12 indexes can be used when employing both right- and left-handed cutters.
The cutters are available for roughing (<50Rz) semi-finishing (<18Rz) and finishing (<12.5Rz). Left-handed cutters are made to order.
Threading tools with the flexibility to thread a broad variety of holes provide the agility many shops need to stay competitive. They may be the only solution for many difficult materials.
