Abstract: An improved rotary cutting end mill which includes an arcuate shaped circular land on the first relief wall which contacts the cutting edge and a slightly angled cutting end. This end mill yields a smooth finished surface on the work piece and can be used at higher rotary speeds. This end mill shows less corner wear, improved rigidity and is operated with less operating noise.
