Abstract
A radial-feed rotating drill tool having a tool holding fixture formed at an eccentric portion of a feed spindle eccentrically mounted in an external spindle. By rotating the feed spindle relative to the external spindle, a feed movement may be initiated with minimum expense. Further, because of the surface-contact mounting of the eccentric shaft portion of the feed spindle in the external spindle, mounting of the tool-holder without play is ensured.

A feed system for a rotating cutting tool, comprising:
- a tool holding fixture adapted to be driven by a spindle;
- adjusting means moving the tool holding fixture in a feeding direction and including a control surface to which a transmission element is associated through which transmission element the tool holding fixture is translatable in a direction of adjustment in the event of a relative movement of the control surface with respect to the transmission element;
- wherein an internal spindle having an outer periphery at which the control surface is formed and which is adapted to be driven synchronously with the spindle or at a predetermined difference in speed with respect thereto by means of a feed motor.
