A machine tool turret having a plurality of tool holders with tension rod-actuated mechanisms for locking the tool head can be rotated to bring a selected tool holder into engagement with jaws of a release unit, applying to the tension rod a force sufficient to compress the disk spring stack thereof and release the tool and to the holder a counterforce which is equal and opposite in direction and prevents the release unit from stressing the bearings of the turret or any spindle bearings which may make the tool holder rotatable.

Method of and assembly for releasably connecting a tool head to a tool

The present invention relates to an improved toolholder for releasably mounting on a tool support member. The toolholder is provided with a forward end for receiving a tool and a shank extending from the forward end for being releasably received in a bore of a tool support member. The shank has a first section for interference fitting with the bore of the tool support member when a rearwardly facing face on the toolholder is in abutment with a forwardly facing surface on the tool support member. The shank has a second section, rearwardly of its first section, for expansible abutment with the bore of the tool support member.
