Abstract: A tool body (12) for a shell end mill (10) is described with at least one helical chip guiding groove (24) arranged at the circumference of the tool body (12) for chip dissipation and at least two receptacles (28) for indexable cutting inserts (26) arranged at the chip guiding groove (24). In this case, the receptacles (28) each comprise a base surface having a bore for receiving an indexable cutting insert fastening screw (34) and at least one first abutment surface adjacent to the base surface. The transition between the base surface and the first contact surface is a groove. In addition, a cutting tool is described with such a tool body, wherein a two-sided indexable cutting insert (26) is attached in each receptacle (28).

Abstract: A rotary cutting tool, such as a milling cutter (10) includes a central hub (12), a cutting rim (14) and a plurality of spokes (22) connecting the central hub (12) to the cutting rim (14). Each spoke (22) is separated by an opening (32) and polygonal in cross-sectional shape formed by two side walls (22a, 22b), two front walls (22c, 22d) and a rear wall (22e). One of the side walls (22a) of each spoke (22) is formed at a pitch angle (42) with respect to a central axis (11) of the cutting tool (10) that is sufficient to cause lift of chips through the opening (32), thereby providing effective chip evacuation during a material removal operation.

Abstract: A rotary cutting tool includes a cutter body having a plurality of insert-receiving pockets. Each pocket includes a bottom support surface, an axial support surface, a radial support surface, a top clearance surface and an intermediate clearance surface extending between the axial support surface and the top clearance surface. A cutting insert includes a helical top surface, a helical side surface, a side surface opposite the helical side surface, a pair of opposed side walls, a bottom surface, and a cutting edge formed at an intersection between the helical top surface and the helical side surface. The cutting insert further includes an undercut for accommodating the axial support surface, the top clearance surface and the intermediate clearance surface of the pocket when the cutting insert is mounted in the pocket.
