Abstract:
In accordance with the invention, a method is provided 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. Thereby, tests have surprisingly shown that the durability of a rasp blade is significantly increased by 30 - 50 %. This increase could be because induction heating is a very fast heating method (austenitisation temperature can be reached within 15 seconds), wherein energy is focused into the rasp blade, and the austenitisation temperature can be reached quite fast throughout the entire rasp blade.

Abstract:
A metallic disk (10) for use with a powered hand tool to remove measured small amounts of material from the surface of a workpiece to smooth the surface thereof. Each disk (10) being formed with an array of strategically placed abrader elements (14) in which each such abrader element (14) is formed with a series of projections (38) in the nature of teeth extending inwardly from an inner wall, defining an opening, toward the edge of the abrader element (14), and being raised above the surface of the disk to engage the surface of the workpiece.
Abstract:
A tool that is designed to cut very hard material using a reciprocating saw. The tool is a rasp made of tungsten carbide that not only cuts into masonry work and other hard materials, but also is capable of not breaking or bending while being used. It is specially heat treated, and also is capable of sanding or smoothing the cut while the cut is being made.
