Abstract: An adapter for operating a keyhole saw (10) on a driving machine includes a driving section (17; 117) for absorbing torque and a threaded section (18; 118) screwed into a threaded hole (20) in the keyhole saw (10). A driving segment (16; 116) is offset radially relative to the adapter axis and is inserted in a form-fit manner into a receiving hole (21) present in the keyhole saw (10). The driving segment (16; 116) is located in an axially extending manner on the end of a driving element (12; 112) which includes the driving element section (17; 117). The threaded section (17; 117) is formed on a threaded mandrel (13; 113) which is situated in the driving element (12; 112) and is non-detachably connected thereto. The threaded mandrel (13; 113) is held in the driving element (12; 112) in a rotatable manner to be axially displaceable to a limited extent.

A plurality of axially projecting mandrels (11) is distributed around the circumference on the opposite end face (13) of the adapter (9).

Abstract: An adapter (9) for a motor-driven machine tool with a tool to be rotatably driven has positive-fit counterpart pieces (10) on one face (16) which are adapted to positive-fit elements (3) of the tool shaft (1). Multiple axially protruding mandrels (11) are arranged along the circumference on the opposite face (13).

Abstract: A sabre saw blade, in particular for metal applications, with a serration that has at least one first tooth spacing and one second tooth spacing, characterized in that in at least a partial region with three first and three second tooth spacings which are always disposed in a directly alternating sequence, the serration has at least two tooth shapes, and at least one tooth is embodied as a roof-shaped tooth having a first tooth back portion with a first clearance angle and a second tooth back portion with a second clearance angle with said tooth back portions being arranged at an obtuse angle and one behind the other in a cutting movement direction, and at least one tooth is embodied as a standard tooth with a straight tooth back, arranged alternatingly, wherein the first tooth spacing is between 10% and 30% shorter and the second tooth spacing is between 10% and 30% wider than 1.81 mm.

Abstract: A jigsaw blade having a clamping end and, adjoining it, a blade-like working body that has a row of saw teeth that is inclined in relation to the clamping end, a spine on the opposite side from the row of teeth, and a tip at the front is therefore safer, easier to use, has higher performance, and is more precise. The jigsaw blade has two tooth row regions of the row of saw teeth that are inclined at different angles in relation to the clamping end.

Abstract: The invention relates to an adapter (11) for operating a hole saw on a prime mover, particularly an electric hand drill, comprising a driving segment (17) for taking up torque and a threaded segment (18) for screwing into a threaded hole present in the hole saw, and at least one driving dog (16) for entering a receiving hole present in the hole saw. In order to obtain a zero-clearance connection between the adapter (11) and hole saw and simple usability when joining the adapter (11) and the hole saw, the at least one driving dog (16) on the end of a driver (12) having the driving segment (17) facing the hole saw is disposed axially protruding, and the threaded segment (18) is formed on a threaded mandrel (13), and the threaded mandrel (13) is permanently rotatably and axially displaceably held in the interior of the driver (12).

Multiple axially protruding mandrels (11) are arranged along the circumference on the opposite face (13).

Abstract: A saw blade for power tools, in particular for power reciprocating saws, includes a blade back (11) and a toothing (12) extending along the lower edge of the blade back and having many saw teeth (13) lined up in succession, In order to increase the blade life and service life of the saw blade, especially in a Thick, stable embodiment, the saw teeth (13) in successive portions (a, b) of the toothing (12) have the same tooth width (az, bz), which, however, differs from that of the saw teeth (13) in the preceding or the succeeding portion (b, a) of the toothing (12).

Abstract: A tool fastening mechanism has a housing 2, in which a clamping opening 3 is embodied for receiving a tapering tool shaft clamping end 4 of a tool part 5. The clamping opening 3 tapers inward in the introduction direction of the clamping end 4 of a tool part 5, and furthermore the tapering sides are inclined toward one another in a plane extending perpendicular to the introduction direction, as a result of which the opening has a trapezoidal cross section, and the length of this cross section decreases away from the orifice of the clamping opening 3. The housing 2 furthermore has a transverse opening 7, which intersects the clamping opening 3 and in which a locking pin 8 is received.

Abstract: A rescue working tool is provided with a luminescent layer on exposed portions of the tool, and preferably over the entirety of the working tool. In a specific embodiment, the working tool is a rescue saw used to cut through debris and mangled structure at a vehicle crash or building collapse site. The luminescent layer can be fluorescent, but is preferably phosphorescent so that the layer emits light when the tool is used in low light or darkness.
