摘要

The invention relates to a reaming tool which has on its enveloping surface substantially helical flutes (1). High hardness cutting materials (2,3,4,5,6) are brazed or soldered to the base material (12) 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.
