Abstract: An indexable insert end mill having multiple triangular inserts spaced axially in overlapping cutting relation in isolated pockets arranged along a gradual helical angle extending axially of the end mill such pattern of axially spaced cutters being repeated at three 120.degree. circumferentially spaced positions on the periphery of the body. In a typical case the three helical rows of inserts each has five inserts equally spaced axially in overlapping relation and circumferentially in 40.degree. increments so that three effective teeth are provided at each of the five axial positions.
