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).
