Cutting tool part assembly

A cutting tool part assembly for a cutting tool, the assembly comprising:

• a first body arranged to form an axially forward part of a cutting tool;
• a clamping element movably mounted relative to the first body to a clamping position to releasably clamp a second body at the first body;
• and
• a fixation element arranged to releasably lock the clamping element in the clamping position, wherein the first body includes an axially forward facing contact face arranged to mate with a corresponding axially rearward facing contact face of the second body, and at least one abutment face being at least partially rearward facing, the clamping element including at least one first clamp face being at least partially forward facing to mate with the abutment face and at least one second clamp face being at least partially axially rearward facing to mate with a portion of the second body, the first body including at least one guide surface extending in a radial direction and aligned oblique to a plane perpendicular to a longitudinal axis of the first body so as to also extend in an axial direction of the first body, the guide surface supporting movement of the clamping element in a radial and an axial direction via an actuation of the fixation element to force and clamp together axially the first body and the second body.
