The water swivel connects the triplex pump and the rotating drill pipe string through a high-pressure hose. It is used to introduce coolant (usually water) into the inside of the diamond drill bit, cooling the drill bit and removing rock cuttings while drilling. During operation, it can withstand pressure without leakage. CDG's water swivel has obtained a test certificate from the International Testing Office. The lifting plug is a wire rope drill bit commonly used on drilling sites. It connects the lifting line and drill pipe to hang the drill pipe joint or lock joint, thereby lifting the drill pipe. The lifter is designed to be used with the main lifter for lifting and lowering the drill pipe string. The lifting plug can meet your drilling requirements.
