End Mill, 5/16" 4 Flute, M42 Cobalt 

Single end 4 flute center cut end mill ground from M42 (8%) cobalt. Used for removing material from a workpiece and leaving a smooth finish. The 4 flute design allows for a high feed rate as less material is removed per flute. If greater swarf removal is desired, consider one of our 2 flute end mills.
