Abstract: An end milling tool having an elongate body which has two flutes defining two elongate lands extending generally in an axial direction of the body. The two lands have first and second flute surface each facing in a direction of rotation of the end mill. The end mill carries at least two peripheral-cutting inserts for peripheral milling, an inner drilling insert for cutting a radially inward portion of a hole, and an outer drilling inserts for cutting a radially outward portion of the hole, each insert being replaceable and of a generally flat configuration having a back face held in contact with the appropriate surface of the body, and a front face opposite to the back face and including a cutting edge. The peripheral-cutting inserts are disposed in a staggered manner alternately in the first and second flute surfaces, such that the first flute surface carries the peripheral-cutting insert which is nearest to the end face of the body.
