  • Drilling head with vibratory effect
    Patent number: 6234728
    Abstract: A mounting attachment for a penetrating tool such as a drilling head on a machine with a machining shaft includes a support provided with means for coupling to a machine; a tool holder provided with means for fixing a tool; means for axially guiding the tool holder relative to the support; means for linking in rotation the tool holder and the support; and elastically deformable suspension means for suspending the tool holder from the support, the suspension means allowing axial translation and self-sustaining reciprocating or vibrating axial movements of the tool holder resulting from a controlled displacement of the support with respect to a workpiece.
