Problems solved by technology

[0005] A problem with the known tools is that the generated chips are not always adequately transported or cleaned
In particular, in the mentioned plunge-cut saw blade applications, chip evacuation is often insufficient, since the chips cannot escape sufficiently well from the gaps created in the workpiece and thus due to heat build-up, machining times and the like Adversely affect other cutting processes

Embodiment Construction

[0046] exist figure 1 and figure 2 The manually guided power tool 1 shown in has in the usual manner a housing 2, an electric drive motor, an electric control device, operating elements such as switches and the like, a transmission and a tool spindle drivable by means of the drive motor 4. The most varied tools 6 for cutting workpieces 6 can be fastened on the tool spindle, so that the tools 6 fastened on the tool spindle 4 can be driven in particular vibratingly for machining the workpieces.

[0047] as in particular Figure 3a to Figure 9b As stated, the tool 6 has a tool body made of steel. The tool 6 is fastened to the tool spindle 4 of the power tool 1 by means of a fastening section 8 having a plurality of through holes in a known manner. The processing section 10 is associated with a toothing 12 which consists of hardened steel. The machining section 10 and / or in particular the toothing 12 can be diamond-coated and / or covered with cemented carbide.

Abstract

The invention relates to a tool (6) for machining a workpiece, having a fastening portion (8) for fastening the tool (6) to a tool spindle (4) which is drivable, in particular drivable in oscillation, of a machine tool (1), and a tool body which has a machining portion (10) with a toothing (12) and a cutout (14). The width of the cutout (14) in the machining portion (10) increases in the direction of the toothing (12). In addition, the invention relates to a machine tool (1) having such a tool, which is fastened to a tool spindle (4) which is drivable by means of a drive motor.

Description

technical field [0001] The invention relates to a tool for machining workpieces, having a fastening section and a tool body for fastening the tool to a drivable, in particular oscillatingly drivable, tool spindle of a power tool , the tool body has a machining section with toothing and a recess. Background technique [0002] A tool for a machine tool which is usually guided manually is known, for example, from document DE 298 25 205 U1. [0003] Tools driven by such generally manually guided power tools can be designed in particular as cutting tools in order to be able to carry out cutting and grinding work. [0004] An exemplary application is the cutting of wooden boards or the creation of cavities in wooden floor panels, for example, so that conductors, for example electrical conductors, can be inserted there. The tools used for this are sometimes called plunge saws, because the saw tool can cut into the wood floor from above. [0005] A problem with the known tools is...
