Title
(DE) RUNDLAUF-SCHNEIDWERKZEUG, Z.B. BOHRER
(EN) ROTATIVE CUTTING DEVICE, E.G. DRILL
(FR) OUTIL DE COUPE ROTATIF, NOTAMMENT FORET
Abstract
(DE)
Ein Rundlauf-Schneidwerkzeug, insbesondere ein Bohrer, enthält einen Werkzeugkopf (1) aus einem harten Schneidwerkstoff und einen den Werkzeugkopf (1) auswechselbar zwischen zwei in Axialrichtung vom Werkzeugschaft (2) vorstehenden Klemmauslegern (13, 14) klemmfixierenden Werkzeugschaft (2). In Fixierstellung liegen die einander kontaktierenden Klemmflächen des Werkzeugkopfes (1) und der Klemmausleger (13, 14) des Werkzeugschaftes (2) auf dem Mantel eines mit der Längsachse (6) des Werkzeugschaftes (2) koaxialen kegelstumpfförmigen Fixierzapfens (7), der sich in dem Einspannende (12) des Werkzeugschaftes (2) zugewandter Einsetzrichtung (17) verjüngt.
(EN)
The invention relates to a rotative cutting device, in particular a drill, comprising a tool head (1) consisting of a hard cutting material and a tool shaft (2), which clamps the tool head (1) between two clamp extensions (13, 14) that project axially from said tool shaft (2), in such a way that the tool head is interchangeable. In the fixed position, the interconnected clamping surfaces of the tool head (1) and the clamping extensions (13, 14) of the tool shaft (2) lie on the surface of a truncated cone-shaped fixing peg (7), running coaxially with the longitudinal axis (6) of the tool shaft (2). Said fixing peg tapers in the insertion direction (17), facing the chuck end (12) of the tool shaft (2).
(FR)
L'invention concerne un outil de coupe rotatif, notamment un foret, qui comprend une tête d'outil (1) fabriquée dans un matériau de coupe dur et une tige d'outil (2) fixant par serrage la tête d'outil (1) de manière amovible entre deux parties saillantes de serrage (13, 14) faisant saillie dans le sens axial de la tige d'outil (2). En position de fixation, les surfaces de serrage, en contact entre elles, de la tête d'outil (1) et des parties saillantes de serrage (13, 14) de la tige d'outil (2) sont placées sur la gaine d'un tenon de fixation tronconique (7) qui est coaxial à l'axe longitudinal (6) de la tige d'outil (2) et qui s'effile dans le sens d'insertion (17) orienté vers l'extrémité d'insertion (12) de la tige d'outil (2).
