FIELD: tool and method for cutting a blank.
SUBSTANCE: gear turning tool has a shank extending along the longitudinal axis of the tool and a cutting head located at the front end of the shank. The cutting head contains a plurality of teeth located along the perimeter. Each of the teeth in cross section perpendicular to the longitudinal axis has a convex rounded contour, which at the first end passes into a convex rounded contour of the first adjacent tooth from a plurality of teeth. At the second end, located opposite to the first end, specified contour passes into a convex rounded contour of the second adjacent tooth from a plurality of teeth. The width of each tooth of the plurality of teeth, measured in cross section as the distance between the first end and the second end, is greater than the height of the corresponding tooth, measured in cross section perpendicular to the width and midway between the first end and the second end.
EFFECT: improvement of quality at polygonal processing is provided.
