FIELD: machine tool engineering. SUBSTANCE: method involves selection of the total length ratio of cutting edges for annular and central parts which are rotated in opposite directions considering the equality of cutting force torques on them. This provides balancing of the resultant torques. The device has carrier 7 fastened to holder 8. Central and annular parts 1 and 2, respectively, of a drill are engagingly mounted. Friction coatings are made on contact surfaces 3. EFFECT: improved quality. 2 cl, 1 dwg
