Abstract: The invention relates to a modular tool comprising a body and an insert for machining a workpiece, wherein the insert comprises a tenon for insertion into a receptacle of the body, wherein the body comprises an access hole, through which the tenon is accessible for an assembly tool, wherein the tenon comprises a profile portion, which, upon insertion of the assembly tool into the access hole, engages with a lateral surface of the assembly tool so that, by a rotation of the assembly tool, the insert can be ejected from the receptacle. Furthermore, a method for ejecting an insert of such a modular tool is specified.

Abstract: Rotary cutting tools are disclosed comprising shanks and replaceable cutting inserts are provided. The shank comprises a pocket which receives an interchangeable cutting insert. The pocket includes a floor with a central pin-receiving hole, opposing pocket centering walls, and torque transmitting pocket drive walls. The cutting insert has a relatively long rear pin receivable in the central hole of the shank. A head of the cutting insert includes insert centering surfaces that contact the pocket centering walls of the shank, and insert drive surfaces that contact the torque transmitting pocket drive walls of the shank. The configurations and sizes of the shank and cutting insert features are controlled to provide improved torque transmission, rigidity and stability during operation of the rotary cutting tools.

Abstract: The invention relates to a rotary tool (2) extending longitudinally from a shank region (8) to a front-facing end region along an axis of rotation (6) and having a carrier (4) with a plate seat (14) and a cutting insert (16) that can be replaceably inserted therein. The cutting insert (16) as well as the plate seat (14) each have radial and axial contact surfaces (40A, B) which are strained against one another with the aid of a clamping screw (50) during assembly of the cutting insert (16). According to the invention, it is provided that the axial contact surfaces (40A, B) and in particular also the radial contact surfaces (42A, B) are inclined in a V shape on one side of the cutting insert (16) and on the other side of the plate seat (14), so that a centering effect is automatically produced during assembly.

Abstract: A cutting head is formed for insertion into a support in a modular rotary tool, in particular a drill. It has a coupling pin onto which outer cover surfaces and torque surfaces are formed as clamping surfaces. The coupling pin has a particular circular groove, which divides the cutting head into a front pin part and a rear pin part. Stop surfaces for an axial pullout safety are formed in the transition area between the two parts. The torque surfaces and the clamping surfaces are arranged in different pin parts. The torque surfaces are preferably formed in the rear pin part.

Abstract: A cutting head is formed for insertion into a support in a modular rotary tool, in particular a drill. The coupling head has a coupling having torque surfaces and clamping surfaces on its outer periphery. The coupling pin is divided into a front pin part and a rear pin part. The front pin part is defined by a circumferential groove. Stop surfaces for an axial pullout safety are formed in the transition area between the two the front pin part and the rear pin part. The torque surfaces and the clamping surfaces are arranged in different pin parts. For example, the clamping surfaces are preferably formed on the front pin part and the torque surfaces are preferably formed in the rear pin part.

Abstract: The rotary tool comprises a support and a cutting head which can be inserted into a pin receptacle of the support via a coupling pin. The support and the cutting head have mutually corresponding surface sections for transferring a radial clamping force and have mutually corresponding torque sections for transferring torque. For an axial pull-out stop device, effective stop surfaces are formed on the pin receptacle and on the coupling pin in the axial direction, wherein, to do this, a stop element is formed, the radial extension of which is smaller than or equal to a radial extension (r2) of the surface sections of the coupling pin and wherein the stop surfaces and the surface section are offset relative to each other in the circumferential direction.
