FIELD: oil and gas production.
SUBSTANCE: one-cutter bit consists of case with inclined journal where cutter is set on. Four flushing channels are made in an upper part of the case to supply drill fluid. An additional flush channel is made in the central part of the bit. It passes through the top of the cutter and through the journal of the bit for circulation of flush liquid and for removal of slime from the bottom hole. This channel directs solution to a back side of the bit case.
EFFECT: increased efficiency of drilling due to improved system of bottom hole flushing.
