ABSTRACT:
A boring attachment has a boring head with a transversely adjustable slide for setting the boring cutter. The slide has a bore for receiving (clamping) a holding device, at a length which is adjustable in the axial direction, so that the holding device is longitudinally displaceable by an amount equaling at least twice the diameter of the recess. Loading at the cutter holder is essentially completely eliminated when the holding device is located in a transversely displaced position which is within the principle operating range of the boring head by providing appropriate bores in the body of the boring head. A relatively small overall height for the boring head contributes to optimal stability of the boring attachment.
