FIELD: drilling of soil and rocks; mining.
SUBSTANCE: group of inventions relates to a drill bit, a method for its production, a method of drilling a borehole, a drilling system. Drill bit comprises a group of elements extending from the surface of the drill bit and being buried therein. These elements are connected to each other by fluid medium to compensate for different forces acting on these elements during drilling operations. Reclamation of the first element in the group of elements causes extension of the second element from the group of elements.
EFFECT: technical result consists in the possibility of controlling the load acting on the bit.
