Standard coupling sleeve, also known as semi bridge coupling sleeve, has a section of the bridge without a thread in the middle. The threaded part of the drill pipe cannot be screwed through the bridge part of the coupling, and the end of the thread can closely adhere to the casing bridge zone. Standard coupling sleeve is particularly suitable for high-torque drilling rigs. Most rope thread (R thread) and trapezoidal thread (T thread) coupling sleeves are with half-bridge type.

Engineering rotary digging teeth are composed of three parts: main alloy (tungsten carbide alloy), matrix (high-quality alloy structural steel), and circlip (spring steel). The main alloy is effectively welded with the parent body through advanced brazing technology, and the shear strength of the brazed seam is ≥180MPa. The mother body rod is equipped with a special groove structure for placing the circlip. The circlip is mechanically assembled and connected to the mother body.
