Abstract: A thread milling cutter (1) includes an integrally formed thread milling tool (10) having a rotational axis (S), a shank portion (24) and a forward cutting portion (34). The cutting portion (34) has at least five insert pockets (42) recessed therein with at least one insert pocket (42) being devoid of an associated support protrusion (46), allowing different insert placements for different thread pitches.

Abstract: A cutting tool has a cutting body with a first insert pocket and an indexable cutting insert removably mounted therein. The first insert pocket has a first seat surface with a plurality of first engagement elements and a first support wall transverse thereto. The cutting insert has upper and lower surfaces and a boundary surface extending therebetween. The lower surface has a plurality of lower engaging elements and the boundary surface has a plurality of alternating first and second peripheral surfaces intersecting the upper surface to form first and second upper cutting edges. In each index position with the lower surface in contact with the first seat surface, the first support wall prevents translation of the cutting insert in a first direction, and the first engagement elements eccentrically contact the lower engaging elements to prevent translation of the cutting insert in a second direction perpendicular to the first direction.
