Abstract

The trepanning tool consists of a mandrel (2) at the end of which two cutter mounts (1) are secured. The end faces of the cutter mounts have smaller tail cutouts in which cutters (5) can be mounted. Radial saw cuts are provided in the bottom faces of the grooves, so that the side faces of the grooves can be forced together by the screws (9). The surface cutters (6) can be clamped on the side faces of the cuttermounts, using clamp plates (7) and screws (8).

Description

Rundlochbohrer mit auswechselbaren Schneiden Die rfindung betrifft einen Rundlochbohrer, von dem alle Schneiden ohne besondere Hilfsmittel auswechselbar sind, Der Bohrer an sich ist bekannt, jedoch werden nach dem heutigen Stand die Schneiden eingelotet. s hat sich gezeigt, daß schon nach @usbrechen einer Schneide, der gesamte Bohrer unbrauchbar wird. Da das Teuerste an dem bohrer der Körper selbst ist, ist dieses Verfahren unrentabel, Aufgabe der Erfindung ist daher, daß jede einselne Schneide auswechselbar ist und aomit der Bohrer eine nahezu unbegrenzte Lebensdauer hat. Round hole drill with interchangeable cutting edges The invention concerns a round hole drill, of which all cutting edges can be exchanged without special tools are, The drill per se is known, however, according to the current state of the art, the Cutting plumbed. It has been shown that even after breaking a cutting edge, the entire drill becomes unusable. Since the most expensive thing about the drill is the body itself is, this process is unprofitable, the object of the invention is therefore that each a single cutting edge is interchangeable and thus the drill is almost unlimited Has lifetime.

Die ZeichnunR Fig. 1 zeigt unter Bezugzeichen 1 den Aufnahmeteil der einzelnen chneiden ( 5 und 6 ) mit angedrehtem Schaft ( 2 ) und echatantbohrrutteraufnshme ( 3 ). Die Zentrierung ( 4 ) wird in den chaft ( 2 ) eingeschraubt. Die äußeren Schneiden ( 5 ) werden durch die Schraube ( 9 ) in ihrer Halterung durch Klemmwirkung befestigt. Die Schneiden ( 6 ) werden in die dafür vorgesehene Vertiefung gelegt und durch die hatte ( 10 ) mittels der Schrauben (8) gehalten.The drawing Fig. 1 shows with reference numeral 1 the receiving part of the individual cutters (5 and 6) with turned shank (2) and echatant drill bit holder (3). The centering (4) is screwed into the shaft (2). The outer Cutting edges (5) are clamped in place by the screw (9) attached. The cutting edges (6) are placed in the recess provided for this purpose and held by the (10) by means of the screws (8).
