FIELD: drilling soil or rock.
SUBSTANCE: invention relates to drilling wells, in particular, to downhole hydraulic motors. Turbodrill comprises a housing, inside of which there is a projection-like rotor in cross-section. Projections on rotor are made with a gap from housing. Between projections there are semi-cylindrical sections shifted relative to projections towards housing, outer side of said sections in sliding contact with inner wall of housing. Projections and semi-cylindrical sections are separated by convex surfaces outwards.
EFFECT: ensuring achievement of stable high torque and rotor rotational speed.
