    Abstract: A cutting tool includes a base body and a cutting head at least partially disposed within a modular pocket of the base body. The modular pocket is formed by at least one wall section removably attached to the base body. In one variation, a non-removable portion of the base body also forms part of the modular pocket. In another variation, the modular pocket is formed by two removable wall sections on opposite sides of the modular pocket. In yet another variation, the removable wall sections include a clamping portion to exert a downward force on the cutting head to enable mounting the cutting head in the modular pocket using an interference fit.

    CPC classification number: B23B31/305

    Abstract: Expansion sleeves are disclosed comprising a body and a flange. The body may be generally cylindrical and includes an inner wall, an outer wall integrally formed with the inner wall, and a pressurized fluid chamber located radially between and encapsulated in the inner wall and the outer wall. The front flange extends radially outward from the outer wall of the body. The front flange may comprise a tool support connection structured and arranged to fasten the front flange to a tool support member. The tool support member may include a pressurized fluid system that communicates with the pressurized fluid chamber of the expansion sleeve. The expansion sleeves may be secured to the tool support member by mechanical fasteners, threading, or combinations thereof. During operation, pressurized fluid in the tool support member communicates with the pressurized fluid chamber of the expansion sleeve to clamp a tool shank.

    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.
