Abstract

A cutting tool, such as a milling cutter, includes a tool body and a plurality of pockets for receiving cutting inserts. Each pocket includes a bottom support surface, an radial support surface, an axial support surface, a first corner relief between the bottom support surface and the radial support surface, and a first stress relief formed in the first corner relief at one end of the pocket. The first stress relief is formed at an angle with respect to a plane parallel to the radial support surface. The first stress relief reduces a tensile stress of the cutting tool during a machining operation. A second and third stress relief may be formed in the first corner relief and/or in a second corner relief.
