The paper reports the measures allowing the increase of worm tool accuracy and efficiency of its use. Basic reasons of arising errors in involute hob cutters are revealed, techniques and methods allowing their minimization are developed. The analysis of geometrical accuracy of such milling cutters is carried out. There is offered a design of a hob cutter allowing the reduction of critical hard alloy use. In view of the fact that geometrical parameter values specified by a designer are not held during gear milling there was carried out a kinematic analysis which has shown that the geometrical parameter values change in the course of motion, but they do not exceed acceptable limits.
