A vibration damping support suitable for a boring bar comprising a shank member, multiple parallel bores extending axially of said boring bar in one end of the shank member and high inertia mass members positioned in each axial bore with a slight circumferential clearance, the mass members being free to move transversely to the shank axis within the circumferential clearance provided. The shank may include a separable extension member or tool nose piece and a connecting member with interengaging retention means for drawing the shank and extension into rigid engagement. |
