Abstract
In present article the courses of low wear resistance of rotary cutting bit body and also the courses of one-sided wear are described. The results of hardness of the cutting bit body from various manufacturers are represented here. In summary a conclusion was made that the utilization of thermal treatment after pressing removes specific structure that can be the course of one-sided wear genesis.
