ABSTRACT:
A tool shank and a replaceable cutting insert are provided for a rotary cutting tool assembly. The tool shank has a drive surface including a central portion, a first portion of generally planar shape extending away from the central portion and a second portion of generally planar shape extending away from the central portion in a direction generally transverse to a central axis of the tool shank. The replaceable cutting insert has a driven surface including another central portion, a first portion of generally planar shape extending away from the other central portion and a second portion of generally planar shape extending away from the other central portion in a direction generally transverse to a central axis of the insert. The central portion of the driven surface has a curved surface transitioning between the first portion and the second portion of the driven surface. A portion of the driven surface of the replaceable cutting insert is engaged by a corresponding portion of the drive surface of the tool shank.
