A quick-change system for a tool holder comprises a machine-side receiving fixture having a hollow-cylindrical extension on which a switching sleeve is displaceably held. Automatic angular alignment of the tool holder upon introduction into the hollow-cylindrical extension of the receiving fixture is enabled by an alignment of the points of the star-shaped end face on the cylindrical holding portion of the tool holder, upon impact against a first set of three balls angularly spaced 120° apart. Once the tool holder has aligned itself in this way, then the first balls make their way into the longitudinal grooves of the cylindrical holding portion, whereby a rotationally fixed coupling is achieved. Upon the further insertion into the hollow-cylindrical extension, an axial securement finally occurs when a second set of three balls are displaced radially inward into associated depressions on the cylindrical holding portion.
The invention relates to a tool head having a shrink-fit chuck (10) that has an axial receiving hole (22), and having a tool (12) that is insertable by way of its cylindrical tool shank (24) into the receiving hole (22), which is open at the front end of the shrink-fit chuck (10), and is fixable therein by thermal shrinking of the shrink-fit chuck (10). According to the invention, it is proposed that the shrink-fit chuck (10) has, in its front end portion, an annular recess (30) that radially widens the receiving hole (22) and is open at the end side, and that a function ring (14) is positioned on the tool shank (24), wherein, in the shrink-fitted state, the tool shank (24) is frictionally fixed in the receiving hole (22) and the function ring (14) sits at least partially in the annular recess (30).
