Abstract: An elongated tool holder has a tool anti-vibration component constituting a mass housing portion provided with an enclosed interior cavity, and an anti-vibration arrangement occupying the enclosed interior cavity. The anti-vibration arrangement includes two vibration absorbing masses disposed within the holder cavity and elastically suspended therein by at least three resilient suspension members contacting an inwardly facing cavity wall surface. The two vibration absorbing masses are made from different materials and have different lengths. A cutting tool is provided with the tool holder.

Abstract: An elongated tool holder includes a mass housing portion having a housing peripheral surface, an outer sleeve having a sleeve hole wall surface, and an anti-vibration arrangement. An elongated groove is formed in one of the housing peripheral surface and the sleeve hole wall surface. In an assembled state of the tool holder, the groove, which is located at a common interface of the housing peripheral surface and the sleeve hole wall surface, forms a groove coolant channel. The groove coolant channel forms part of an overall tool holder coolant channel which is spaced apart from the anti-vibration arrangement, and thus isolates the coolant from the anti-vibration arrangement. A cutting tool incorporates the tool holder.

Abstract: An external turning tool includes an elongated tool body with opposite clamping and cutting portions which define an axial direction therebetween. The cutting portion includes a damping mechanism with an elongated damping member which defines an elongation axis. The elongation axis forms a non-zero damping member angle with the axial direction.

Abstract: An elongated tool holder includes a tool anti-vibration component having a component housing portion and an anti-vibration arrangement. The anti-vibration arrangement includes an enclosed interior component cavity formed in the component housing portion. The anti-vibration arrangement also includes a vibration absorber portion disposed within the component cavity that is integrally formed with the component housing portion to have unitary one-piece construction therewith. The vibration absorber portion includes a vibration absorbing mass and at least one elastic suspension member through which the vibration absorbing mass is connected to the component housing portion. The component cavity includes an oscillating space located between an inner surface of the component housing portion and the vibration absorber portion. The vibration absorbing mass is configured to oscillate within the oscillating space upon elastic deformation of the at least one suspension member.

Abstract: A cutting tool holder has a holder body and a vibration damping weight assembly. The holder body has opposing first and second side surfaces and a top surface extending therebetween, and an insert mounting portion located at a front end of the holder body adjacent to the top surface. A weight aperture opens out to the first and second side surfaces and has an aperture inner surface. The weight assembly is located within the weight aperture, having a first and second weight portions, a damping ring located along the aperture inner surface, and an actuating member interfacing and urging the first and second weight portions away from one another, such that each weight portion presses against the damping ring within the weight aperture.
