Abstract: A cutting head attachment assembly for a cutting tool includes a body forming an axially forward part of the cutting tool attachable to a cutting head via a clamping element and a fixation element. A guide surface provided at the body or cutting head extends in both a radial and an axial direction to support movement of the clamping element in both the radial and axial directions via actuation of the fixation element to force and clamp together axially the head and body.

Abstract: A tool body includes a damping apparatus for damping vibrations in a machining tool having, besides the tool body, a member with at least one cutting edge to be secured to the tool body. The damping apparatus is arranged in an internal room of the tool body and includes a damper mass body with an axial bore and a central tube extending through the bore and which is rigidly secured to the damper mass body inside the through bore. A central tube is also at both ends thereof rigidly connected to a tool body fixed part and the central tube is made of a material with a spring property allowing the damper mass body to oscillate in the internal room perpendicularly to the longitudinal extension of the central tube.
