Tool body for a shell end mill and cutting tool

A tool body for a shell end mill, the tool body comprising:

• at least one helical chip-guiding groove arranged on a circumference of the tool body for chip dissipation;
• and at least three receptacles arranged at the at least one chip-guiding groove, the at least three receptacles including at least a first receptacle a second receptacle and a third receptacle,
• wherein the receptacles each comprise a base surface comprising a bore for receiving an indexable cutting insert fastening screw and at least one first abutment surface located adjacent to the base surface, the first abutment surface being substantially perpendicular to the base surface,
• wherein a transition between the base surface and the first abutment surface is a groove;
• wherein a two-sided, indexable insert is attached to each receptacle;
• wherein the base surface of the first receptacle for the at least one helical chip-guiding groove has a first angle with respect to a longitudinal axis of the tool body;
• wherein the base surface of the second receptacle for the at least one helical chip-guiding groove has a second, different angle with respect to the longitudinal axis of the tool body;
• and
• wherein the base surface of the third receptacle for the at least one helical chip guiding groove has a third angle with respect to the longitudinal axis of the tool body, and wherein the third angle is different from the first angle and the second angle.
