Solid Carbide End Mills Tooling by DIJET DV-Coated End Mill for Heat Resistant Alloy DV-SCMSTYPE Features of DV-SCMS type The high efficiency machining Unique designed cutting by multi cutting edge. edge geometry control chatter problem Large rake angle achieves Due to 45 degree helix angle, sharp cutting performance cutting force is low and less weld metal. The high efficiency machining is possible by Newly developed VALUE COATING trochoidal milling.
