A reciprocating filing tool. The reciprocating filing tool includes a housing having a first end opposite a second end, wherein a handle is affixed to the second end. A shaft is slidably disposed within the housing, and a motor is operably connected to the shaft. The motor causes the shaft to move in a reciprocating linear movement when the motor is activated. A trigger disposed on the handle, wherein the trigger activates the motor when actuated. A plurality of files are removably securable to a distal end of the shaft. A plurality of clips are disposed on an exterior of the housing and can removably receive the plurality of files therein.

A method for producing a tire rasp blade for mounting on a rasp hub is described. The tire rasp blade has a blade body and blade teeth. A main part of the tire rasp blade is austenitized by heating the main part to an austenitization temperature. The tire rasp blade is then tempered. The austenitizing process is performed by induction heating the tire rasp blade until the austenitization temperature is reached. The austenitizing process is followed by a quenching process, wherein the quenching is started before austenitization temperature is reached, whereby the quenching process briefly overlaps the induction heating. A tire rasp blade is also described.

A tire rasp blade for a buffing machine including least three arc segments of buffing leading edges with coarse and fine pitches with variable segment angles are arranged in between the terminal ends, to form arcuate working end with a working end angle. The first arc segment is defined by a coarse pitch and is arranged at one terminal end followed by an arrangement of second and third arc segments that are defined by an incremental fine pitch.

The present invention refers to a mini-blade (1) which body (2) has an inner edge (4) in which there is, at least, one transversal tab (6) that constitutes a retention means of the mini-blade (1) in an adapter device (20); between the inner (4) and the external (3) edges, the body (2) has the sufficient extension to form clamping portions (7)(8) that allow the application of clamping peripheral tabs (30). The invention also refers to an adapter device (20) that, for the mounting of a rotary work structure (40) of pneumatic roughing down, includes clamping sets (20) composed of ending supports (21)(22) and intermediary separator supports (23), all of which have clamping transversal peripheral tabs (30) that form jaws capable of clamping the clamping positions (7)(8) of the mini-blade (1). The different supports (21)(22)(23) that form the clamping sets (20) are arranged attached one to another, in train, with the mini-blades (1) interspersed in their jaws, in such a way that the toothed external edge (3) of these last ones protrudes from the clamping set (20).

Methods and apparatus for treating a shaped tire rasp blade for mounting on a rasp hub, said tire rasp blade comprising a blade body and blade teeth, wherein the method comprises an austenitising process for austenitising the main part of the tire rasp blade by heating it to an austenitisation temperature, a subsequent quenching process and finally a tempering process for tempering the tire rasp blade. The austenitising process is performed by using induction heating for heating of said tire rasp blade, increasing the durability of a rasp blade by 30-50%. Induction heating is fast (austenitisation temperature can be reached within 15 seconds), wherein energy is focused into the rasp blade, enabling austenitisation temperature to be reached quite fast throughout the entire rasp blade.
