End Mill, 5/16" 4 Flute, HSS, 3-3/4" Long Reach 6217  (Discontinued) 

Single end 4 flute center cut end mill ground from solid high speed steel. 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.

This end mill is classified as extra long because its overall length and cutting length (length of flute) is longer than standard 5/16" milling diameter end mills. This end mill has an overall length of 3-3/4" and a flute length of 2". The shank is 3/8".
