Abstract
A roughing end mill comprises an end mill body and plural inserts which are placed on an outer circumference of the end mill body with a predetermined distance apart from each other in the axial direction of the end mill body, wherein the plural inserts form plural insert rows which are provided in a circumferential direction of the end mill body, where the inserts are offset in the axial direction from each other between the different insert rows which are adjacent in the circumferential direction. The inserts have waveform cutting edges which face towards an outer circumferential side of the end mill body. One insert of one insert row and an insert of another insert row are positioned such that the waveform cutting edges of each of these inserts make up a waveform cutting edge row whose phase is continuous on a rotation trajectory around the axis.
