ABSTRACT:
A tool mount for a tool holder having a tubular collar with an inwardly projecting rim has a shaft centered on an axis and formed with an axially centered main bore having an outer end formed as a seat complementarily engageable around the collar and a transverse bore crossing the main bore. An actuating bolt in the main bore has a head engaged in the collar in the seat and is formed with a transverse bore aligned with the shaft transverse bore. A retaining element is engageable between the bolt head and the holder rim and the bolt is axially displaceable between an inner position pressing the retaining element radially outward into locking engagement with the holder rim and an outer position with the retaining element retracted radially inward out of locking engagement with the holder rim. An ejector sleeve axially displaceable on the bolt in the bore is axially outwardly engageable with the holder collar in the seat. A setting rod rotatable in the transverse bores about a transverse axis perpendicular to the main axis is formed with a locking cam eccentric to the transverse axis and engageable with the bolt to displace same between its positions and an ejector cam eccentric to the transverse axis and engageable with the ejector sleeve to displace same outwardly against the holder collar on displacement of the bolt into the outer position.
