Tool-holder equipped with shock-absorbing means

摘要

The holder (1) has a damping unit (2) in form of an elongated body arranged in an end of a housing (3) of the holder, where the housing is of appropriate shape and size and is closed at its end by a reception body (4) for receiving a boring head. The unit (2) made of high density steel presents radial absorption, and is provided with elastically deformable units (5) that extend between an envelope of the unit (2) and a wall of the housing by clamping between the wall of the housing and the unit (2), where ends of the unit (2) extend in the housing without stress.
