The invention relates to a machine tool with a tool receiving device that is movable around an output shaft. The tool receiving device is designed to hold a tool device on the machine tool such that the output shaft and a tool rotation axis substantially coincide. The tool receiving device has at least one torque transmission region and a holding device. To transmit a driving force to the tool device, the torque transmission region has at least two output area regions arranged at a distance from said output shaft, with each having a multiplicity of surface points. The tangent planes to said surface points are inclined in regard to an axial plane including said output shaft. The tangent planes are inclined in regard to a radial plane extending perpendicularly to the output shaft. The machine tool thus transmits the output torque to the tool device via the tool receiving device.

Power tool

A sawing tool, in particular a saw blade, includes: at least one connection region, in particular a shaft, for forming a connection to a tool holder of a hand-held power tool; at least one main body, in particular a carrier, which is connected to the connection region and is designed in one piece; at least one set of saw teeth which is located on the main body; and a plurality of reduction grooves which are located on the main body, in particular introduced into the main body by removing material, and which have a main extension running transversely to a cutting edge of the saw teeth. The reduction grooves extend at least over more than 50% of a total transverse extent of at least one flank of the main body from the cutting edge towards a rear side of the main body, the rear side facing away from the saw teeth.

Tool accessory

The invention relates to a tool device which is suitable for use with a machine tool, in particular a hand guided machine tool, having a driving device moving, in particular in an oscillating manner, around a driving axis. The tool device has an attachment device which allows it to be fastened on a machine tool such that its driving axis and an axis of rotation of the tool substantially coincide. The attachment device, for absorbing the driving force, has at least two driving area regions, which are spaced apart from said tool axis of rotation and each has a plurality of surface points. The tangent planes to said surface-area points are inclined in regard to an axial plane, which encloses the tool axis of rotation. Furthermore, said tangent planes are inclined regard to a radial plane which extends perpendicularly to the tool axis of rotation. This means that the torque introduced into the tool device by the machine tool, via the driving device, is reliably absorbed.

The tool receiving device is designed to hold a tool device on the machine tool in such a manner that the output shaft and a tool rotation axis substantially coincide. The tool receiving device has at least one torque transmission region and a holding device. In order to transmit a driving force to the tool device, the torque transmission region has at least two output area regions that are arranged at a distance from said output shaft and each have a multiplicity of surface points. Here, the tangent planes to said surface points are inclined in regard to an axial plane which includes said output shaft. Furthermore, the tangent planes are inclined in regard to a radial plane which extends perpendicularly to the output shaft. In this way, the output torque is transmitted reliably to the tool device by the machine tool via the tool receiving device.

Saw blade

In accordance with one embodiment, an integrally formed saw blade includes a cutting edge extending along an axis from a distal front tip to a proximal rear portion, the cutting edge includes a portion with cutting teeth and a portion with no cutting teeth. A lateral edge extends along the axis from the distal front tip of the saw blade to the proximal rear portion of the fixing shank. A blade portion, with a maximum height defined by the cutting edge and the lateral edge, terminates at a corner. A fixing shank with a maximum height defined by the cutting edge and the lateral edge that is shorter than the blade portion terminates at the cutting teeth. A transition region extends from the fixing shank to the blade portion, and at least two spaced apart impressions are formed in the transition region but do not extend into the blade portion.

Keyhole saw blade or sabre saw blade for a power tool

A saw blade includes a blade base with an arcuate cutting edge. The cutting edge is curved to a lesser extent than a circular arc with a radius that corresponds to the distance between the axis of rotation of the saw blade and the cutting edge.

Saw blade for a machine tool

The invention relates to a machine tool, in particular a hand held machine tool, which has a tool-accommodating device which can be moved, in particular in oscillating fashion, about a drive axis, in order to retain a tool device on the machine tool. The tool-accommodating device has at least one clamping device, at least one retaining device and at least one locking device. The retaining device can be moved from at least one first, open position into at least one second, closed position. It is also the case that the retaining device can be forced by a clamping force, by way of the clamping device, preferably in the closing direction from said first, open position in the direction of said second, closed position. The locking device can be moved between at least one first, locking position and at least one second, unlocking position. It is possible here for said locking device to block movement of the retaining device in at least one locking position. A force applied to the locking device directly or indirectly by the tool device moves said locking device from one of said locking positions into one of said unlocking positions. This allows the tool device to be inserted particularly quickly and straightforwardly into the machine tool.

Machine tool with tool-accommodating device

A keyhole saw blade or sabre saw blade for a power tool comprises a base blade having a cutting edge and a securing shank designed as one piece with the base blade. At least one impression is formed into the base blade or the securing shank.

A method for producing a cutting unit segment of a cutting unit of a machine tool separating device, includes at least one cutter support element and at least one cutter element. In at least one step, the cutter element is molded on the cutter support element by a drawing process in an at least partially staggered manner relative to an outer surface of the cutter support element.

A tool has at least one point, at least one working edge, at least one edge, which connects to the point and is located opposite of the working edge and which has at least one first edge region that is straight and forms an inclination angle between 0&#xb0; and 2.5&#xb0; with the working edge. The edge has a second edge region, which has a different inclination than the first edge region.
