    This paper solves the problem of increasing the productivity of machining, as well as reducing both the cost of cutting tools and equipment downtime associated with tool failures and its replacement.
    The task of increasing the strength characteristics of the hard alloy tools necessitates the development of modification methods that affect the entire volume of the material. The requirements that are put forward for these methods are low cost, environmentally friendly, and make its application in the conditions of the machine - building enterprise possible. The method of processing by a pulsed magnetic field satisfies these requirements [1-4].
    It is found that the modification of hard alloy metal by pulsed magnetic field processing leads to the increase in its homogeneity, the decrease in the thickness of the crack layer, the stabilization of mechanical characteristics, and the increase in the bending strength.
    Modification of carbide cutting tips by pulse magnetic field machining is carried out on the equipment, which consists of a pulse generator with a power supply and an inductor. The influence of the pulsed magnetic field on the strength and wear resistance of carbide cutting tips for improving the performance of tooling and reducing the operation and tool costs is investigated. Technological modes of pulsed magnetic field machining by combined technologies (pulsed magnetic field processing + vacuum plasma coating) of samples of tool materials and carbide cutting tips have been worked out.
    The application of the method of "destructive feeding" for laboratory and production evaluation of structural strength of carbide tips is justified. The method of step-by-step increase of cutting conditions (feeding and cutting speed) allows to implement the principle of extrapolation on loads by gradually increasing loading of strength and wear rate of the tool material.
    It was found that by roughing of materials with carbide cutting tips hardened by pulsed magnetic field, a multiple tool burnishing with several degrees of slowdown and acceleration of the wear process takes place. This leads to wear resistance increase of carbide cutting tips.
