Cone Bit

Due to the simple structure, large bearing space, and easily miniaturized size, the single roller cone bit is more suitable for formations with higher strength and plasticity than the tricone bit, and it is also suitable for hard interlayers and other complex formations that are difficult for PDC bits to deal with. It can increase the ROP of the sidetracking machine, shorten the drilling cycle, and thus reduce the dilling cost. It can be applied to increased inclination, stable inclination and small hole dilling. We recently developed a single roller cone bit which is the most commonly used YC series . Diamond composite inserts at top of the cone enhance the wear resistance and improve the service life of the bit. New hydraulic structure improves the cleaning ability on the rollers and optimizes the flow at the bottom of the well. The gauge protection uses large diameter ball inserts, so that the bit has good gauge function and reverse reaming function. This series of bits is suitable for small hole diling operations such as window sidetracking and deepening in old wells.
