Abstract: In a packaging for a circular insertion tool, in particular a circular saw blade, with a planar main body, which has a holding flange for fixing an associated insertion tool on the planar main body, the planar main body has a polygonal outer circumference, with a tab which is bendable in the direction of the holding flange being arranged on at least one side of the polygonal outer circumference.

Abstract: A quick clamping device for a machine tool, in particular for a hand-held machine tool, includes at least one clamping device that is moveably mounted in particular on an output spindle of the machine tool that can be rotationally driven about an output shaft of the machine tool, at least for axially securing a tool device, in particular an insert tool, on the output spindle of the machine tool. The quick clamping device includes at least one movement securing unit having at least one movement securing element arranged in particular on the clamping device, which is provided for a movement of the tool device, in particular in a rotary drive position, and/or for securing the tool device.

Abstract: A positioning device for a machine tool, in particular for a hand-held machine tool having a rotationally driveable output spindle, includes at least one positioning unit which is provided to stop and/or retain at least one output spindle of the machine tool and/or an insert tool arranged on the output spindle of the machine tool in at least one defined position. The positioning unit is provided for stopping and/or retaining the output spindle and/or the insert tool arranged on the output spindle in at least one defined position in an automatic manner, in particular without a user intervention, in particular starting from a working movement of the output spindle and/or of the insert tool arranged on the output spindle.

Abstract: A circular saw blade, in particular for the machining of non-metallic workpieces, includes a circular saw blade body and a plurality of saw teeth, wherein the saw teeth are attached to the periphery of the circular saw blade body. The saw teeth have at least one first saw tooth and at least one second saw tooth. The first saw tooth has a saw tooth geometry which is different than the second saw tooth. The first saw tooth has at least two cutting edges and the second saw tooth has at least two cutting edges.
