DRILLCO - 20.0,4 FLUTE SINGLE END END-MILL 5/8" SH - 565A200

The multi-flute end mill has a better finishing capability than a 2-flute end mill. At any given instance, at least one and often two of the teeth are solidly in the cut. The cutting action is smoother than that of the 2-flute end mill, with less chatter.

Center cutting tip for plunging, pocketing and holemaking
Multiple flutes (4 or 6) produce a better surface finish and less chatter
