Embodiment Construction

[0036] All figures show a rotary oscillating cutting tool in the form of a rotary oscillating saw blade or plunger saw blade for a power tool.

[0037] exist figure 1 The rotary oscillating cutting tool 1 shown in FIG. 2 comprises an at least substantially rectangular or arcuate stem piece 2 and a bent holder 3 connected to the stem piece 2 . On the free end side facing away from the holder 3 , the backbone piece 2 is provided with a cutting edge 4 with cutting teeth. The holder 3 comprises a shaft receptacle section 9 which has a fixed receptacle 5 for receiving a tool shaft 6 of a machine tool which performs a rotationally oscillating movement about the axis of rotation 7 . The fastening to the tool shaft 6 takes place by means of a detent opening 8 which is formed annularly around the central fastening recess 5 in the shaft receiving section 9 .

[0038] Furthermore, the holder 3 comprises a transition section 10 and a connecting section 11 via which the connection to the...

Abstract

A rotary oscillation cutting tool (1) for a machine tool has a circular-segment-shaped stem blade (2) with a working edge (4) and a holder part (3) for the holder on a shaft of the machine tool. The holder part (3) is for an improvement of rigidity next to the stem blade (2) provided with a reinforcing element (12) formed from one piece.

Description

technical field [0001] The invention relates to a rotary oscillating cutting tool for a machine tool, in particular a rotary oscillating saw blade. Background technique [0002] A number of different rotary oscillating cutting tools are known. In this case, a rotary oscillating cutting tool is to be understood in particular as a tool having a main piece, a working edge and a holder connected to the main piece for fastening to a preferably rotationally oscillating drive shaft of a power tool. In this case, the working edge is preferably provided as a cutting edge, for example with cutting teeth, cutting particles and / or cutting bodies. [0003] DE 203 08 797 U1 describes a saw blade for saws with a rotationally oscillating drive movement. The saw blade has an approximately rectangular stem blade with a cutting edge and a recess formed integrally with the stem blade and having a recess for receiving a tool shaft of a power tool. The cutting edge is implemented rectilinearly...
