Безлезвийная буровая коронка, оснащенная цилиндросферическими твердосплавными вставками и имеющая конусное соединение с буровой штангой, отличающаяся тем, что цилиндросферические вставки устанавливаются с углом наклона геометрических осей к оси коронки равным углу конусности соединения коронки со штангой, причем наклон осей вставок выполняется противоположным направлению вращения коронки, а взаимное расположение соседних вставок обеспечивает образование выраженных перьев коронки.A bladeless drill bit equipped with cylindrical spherical carbide inserts and having a conical connection with the drill rod, characterized in that the cylindrical spherical inserts are installed with an angle of inclination of the geometric axes to the axis of the crown equal to the angle of taper of the connection of the crown with the rod, and the inclination of the axis of the inserts is performed in the opposite direction of rotation of the crown, and the relative position of adjacent inserts provides the formation of pronounced feathers of the crown.
