Abstract
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.
