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.
