In an interface structure comprising a first assembly and a second assembly wherein the first assembly includes a cavity having a truncated cone-like section, a stop surface effective in the axial direction and a second assembly including a trunnion with a truncated cone-like section for abutment on the truncated cone-like sleeve section of the first assembly and an abutment surface for contacting the abutment surface of the first assembly, between the cavity and the trunnion a bayonet-like locking structure is provided in the interface structure whereby handling with a high repetition accuracy with regard to the position of the assemblies to be joined is ensured.

A coupling mechanism designed to removably attach a reamer to the distal end of a spindle or shaft is disclosed. The coupling comprises a collar having an annular sidewall that defines a collar throughbore, the collar annular sidewall comprising a plurality of spaced part first slots that at least partially extend through the sidewall and a shank disposed within the collar throughbore. The shank is constructed with a shank annular sidewall in which a plurality of spaced apart second slots at least partially extend therethrough. A bias member that provides a bias force in a distal direction that acts on the collar is incorporated within the mechanism. The collar is capable of sliding in an axial direction such that the first and second slots become aligned to secure the cross bar of a reamer therein.

A power tool, in particular a hand-held power tool, includes a tool-holding device that rotates about an output axis. The tool-holding device is configured to hold a tool device on the power tool such that the output axis and a tool rotation axis substantially coincide. The tool-holding device has at least a driver device and a clamping device that is movable relative to the driver device. To transfer a driving force to the tool device, the driver device has at least one torque transfer region that is arranged at a distance from the output axis. The driver device and the clamping device are configured to reach through a cut-out of the tool device, which cut-out extends through the entire material thickness of the tool device, and to clamp the tool device via the clamping device, which is movable substantially in a direction radial to the output axis.

A hybrid holding device used in a milling machine, comprising a base with mounting structures for detachably fastening the hybrid holding device securely onto a workbench of the milling machine in a fixed stationary position. The hybrid holding device further includes moveable multi-jaw assembly that includes at least three jaws that directly receive and securely hold a workpiece without an adapter.

An adapter for holding a tool in a collet chuck, the adapter containing an external taper to accommodate the adapter in the collet chuck. The adapter has a thread for fastening of the tool, and several shape-mated elements are arranged on an outer surface of the external taper for non-rotational holding of the receptacle body during fastening of the tool.

A clamping apparatus with a control mechanism includes a cam, a cam post, a handle, and a handle plate. The cam is configured to rotate into a clamped position in which the clamping apparatus is in a clamped state and an unclamped position in which the clamping apparatus is in an unclamped state. The cam post is rotatable with the cam. The handle is movable into a first position and a second position. The handle plate is rotatable with the handle. The handle plate is configured to rotate the cam post in a first direction when the handle moves from the first position to the second position. The handle plate is configured to rotate in a second direction without rotating the cam post in the second direction for a predetermined distance when the handle moves from the second position to the first position. The first direction is opposite to the second direction.

An accessory for use with an oscillating power tool includes an attachment plate and a raised annular rim extending from the attachment plate. The raised annular rim has a central recess and a keyed sidewall with a star shape configured to be engaged by a first mating geometry of an oscillating power tool. The raised annular rim may further include a receiving portion formed thereon configured to be engaged by a second mating geometry of an oscillating power tool.
