FIELD: mining.
SUBSTANCE: rock-destroying tooth includes shank and working head formed by cross-over of two cylinders installed at an angle to each other and ellipsoid of rotation which axis coincides with axis of tooth shank. Larger radius of ellipse may exceed smaller radius of tooth cross-section ellipse more than two times.
EFFECT: simplifying tooth structure, improving efficiency of tooth operation, reducing energy consumption during rock destruction process.
