Magnum 5/16" (7.94 mm) 4 Flute Cobalt End Mill (EM516C)
Maintain a sharp cutting edge when machining difficult, heat-sensitive alloys such as stainless steel. The Magnum EM516C 4 Flute Cobalt End Mill is manufactured from M42-grade substrate to provide the red-hardness required for high-thermal applications. This cobalt-enhanced tool minimizes edge wear in high-tensile materials where standard HSS fails, ensuring consistent dimensional accuracy and a superior surface finish in demanding metalworking environments.
