A chucking apparatus for chucking an object contains a basic body which has a receiving space in which the object can be disposed. A chucking device is provided with a chucking nut which is screwable onto the basic body and by the chucking nut being screwed onto the basic body the object disposed in the receiving space can be chucked non-rotatably. The chucking nut has a plurality of roller bodies having a defined roller engagement structure. The roller bodies are held in an axially rotatable manner on a chucking body of the chucking nut and are arranged distributed in the circumferential direction on the chucking nut. The rollers by their roller engagement structure are in engagement with the basic body engagement structure of the basic body.

A toolholder (14) for fastening a chipping tool is specified, having a holding body (22) extending along a holding center axis (20), having a first tool-side end (24) and a second toolholder-side end (26) opposite the first end (24), wherein the holding body (22) comprises at least one coolant supply channel (28) spaced apart from the holding central axis (20), wherein a discharge element (34) is arranged at the second end (26), in which at least one channel-like discharge nozzle (36) is formed, which is fluidly connected to the coolant supply channel (28) and through which coolant can be ejected onto a tool held in the toolholder (14), and wherein a nozzle longitudinal axis (40) extending centrally in the discharge nozzle (36) is inclined to the holding center axis (20) in the radial direction and in the circumferential direction. Furthermore, a cutting apparatus (10) having a toolholder (14) is specified.

An axial machining tool includes a cutter holder, a collet, a dust blower nut, and a cutter. The cutter holder has a receiving groove. The collet is extended into the receiving groove and has a containing space. The dust blower nut is sleeved on the collet and has a body, at least one blade, and a positioning element. The body has a threaded hole, a connecting groove, and at least one engaging groove. The threaded hole and the connecting groove are formed in the body and communicate with each other. The at least one engaging groove is formed on the body. The at least one blade is detachably mounted in the at least one engaging groove. The positioning element is mounted to the body and positions the at least one blade on the body. The cutter is extended into the containing space. A dust blower nut is also provided.

A tool holder includes a tubular body having a shank on a first axial end portion, a tool gripping portion on a second axial end portion, and an elastic segment interposed between the shank and the tool gripping portion in the axial direction of the body. The elastic segment is more elastically deformable along the axial direction and around a circumferential direction of the tubular body than the shank and the tool gripping portion owing to a plurality of voids that extend through the elastic segment from an outer peripheral side of the tubular body to an inner peripheral side of the tubular body. Each of the voids includes segments that extend around the circumferential direction and along the axial direction of the tubular body.

A handle assembly is disclosed for firmly holding a surgical tool. The handle assembly comprises a handle and a locking mechanism attached to the handle. The locking mechanism includes a locking ring, a collet, and a compressible locking pin engageable with the locking ring and collet. The locking ring is moveable between first and second positions relative to the handle. The first position is an unlocked position whereby the locking pin is in a decompressed state relative to the locking ring and the collet. In the first position, a surgical tool may be inserted and withdrawn from the collet of the locking mechanism. The second position is a locked position whereby the locking pin is in a compressed state relative to the locking ring and the collet. In the second position, a surgical tool is anchored in the collet of the locking mechanism.

The invention relates to an interface between a collet holder and a tool adapter, said interface being simple in construction and in which the insertion of a tool adapter is possible in a simple manner even in confined spaces.

A tool holder has a base element, a deformable receiver for clamping a tool and at least one locking element configured for preventing an axial extraction of the tool from the tool holder through engaging a corresponding opposite element at the tool. The at least one locking element is integrally configured in one piece with the receiver.

An angle head holder has a steering assembly and a holder assembly rotatably mounted in the steering assembly. The holder assembly has a cutter spindle, a threaded rod, multiple balls, and a collet. The cutter spindle has a central hole and a first annular groove radially formed in the central hole at a position near a rear end of the cutter spindle. The threaded rod has a second annular groove aligning with the first annular groove to form a ball groove between the threaded rod and the cutter spindle. The balls are arranged in the ball groove. The collet is inserted in the central hole of the cutter spindle from a front end of the cutter spindle and is connected to the threaded rod with threaded connection.
