the invention relates to a reaming tool which has on its enveloping surface substantially helical flutes . high hardness cutting materials are brazed or soldered to the base material of the reaming tool . thus , a cost - favourable manufacture of a reaming tool is provided . the invention makes it possible for the shaft and the head of the reaming tool to be made of solid carbide metal , the shaft and the head preferably constituting the one and same integrate body . a considerable improvement is obtained as regards the processing quality , the speed , and also the durability of the tool . this is based on the fact that the chip removal elements are sintered or brazed into the base body of the head initially shaped with the helical flutes , so that a material joint of high quality is provided compared to other joints .
