Beschreibung
Zusammenfassung:	A tool body (2) 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 (7) of the tool body and comprises a damper mass body (9) with an axial bore (10) and a central tube (11) extending through the bore and which is rigidly secured to the damper mass body inside the through bore. A central tube (11) is also at both ends (12, 13) thereof rigidly connected to a tool body fixed part (14, 15) and the central tube is made of a material with a spring property allowing the damper mass body (9) to oscillate in the internal room (7) perpendicularly to the longitudinal extension of the central tube.
