FIELD: metal working, namely designs of teeth working tools with round cutters used for making cone gear wheels with circular teeth. SUBSTANCE: head includes housing with round cutters mounted in radial openings of housing by means of cutter holders. Position of cutting edge of each round cutter is determined by means of radial adjustment mechanism having wedge stop mounted coaxially relative to housing and being in the form of annular truncated cone; and worm gearing. Each cutter holder is in the form of worm gear wheel whose teeth are arranged on its outer cylindrical surface. Worm has central opening for placing screw clamp for rigid fixation of worm in housing. EFFECT: enhanced accuracy and quality of gear cutting due to increased rigidity of tool in the result of elimination of backlashes at fixing gearing in housing of head. 2 dwg
