Abstract

A cutting insert (10) of a rotary drill tool (1) for cutting metal comprises a head (14) and a neck extending along a longitudinal axis (12). The head has an axially forward-facing cutting region (13). At least the neck is configured for enabling releasably mounting at a support body (11). The head is formed by at least two lobes (33) each having a radially outermost envelope surface (23). Each lobe comprises a radially and axially extending torque transfer surface (17) configured for abutment contact with a corresponding torque transfer surface(29) of the support body. In a plane extending perpendicular to the longitudinal axis, the torque transfer surface has an orientation relative to the radial direction (R<T>) at an angle (α) in the range 15 to 45°, or 22 to 35°, or 28 to 33°, or 28 to 29°. A corresponding support body and a rotary drill tool.
