Abstract:
A cutting tool includes a tool body having a plurality of pockets for receiving cutting inserts. Each pocket includes a bottom support surface, an axial support surface, a radial support surface and a corner relief between the bottom support surface and the radial support surface. A non-circular recess is formed proximate the pocket, and a coolant passage is disposed within the recess. The recess reduces a tensile stress of the cutting tool during a machining operation.
