Slovenski The high-pressure rotary Jet-jet Anchor Drill Bit is a nozzle that includes a body, bearings, fixed rings, and steel plates. Through the setting of bearings and fixed rings, the friction between the steel plate and the rotary jet anchor nozzle is reduced, the service life of the rotary jet anchor nozzle is increased, and the problem of simultaneous rotation of the steel plate and the rotary jet anchor nozzle is solved, thereby improving construction efficiency and construction quality. The high-pressure rotary jet anchor nozzle has the characteristics of integrated construction, reasonable structural design, anchor ring design, and reduced risk of hole collapse.
