    摘要： A tool body (2) includes a damping apparatus comprising a damper mass body (9) with an axial through bore (10) and a central tube (11) received in the through bore while being surrounded by a cavity (14). An elastic element (15, 16) is arranged on each side of the damper mass body and provided with two socket-like portions (25, 26) extending axially through a central hole of two disc-like members (19, 20) clamping the elastic element (15,16) therebetween. These socket-like portions (25,26) project in a rest state of the elastic element (15,16) axially beyond the respective axially directed side of the respective disc-like member (19,20) and are in an assembled state of the tool body (2) compressed for sealing the cavity (14) with respect to the exterior.
