API 17 1/2" Tricone Bit IADC637 for Oil well Drilling , water well drilling
The Tricone roller cone bit is the most widely used drilling bit. When the roller cone bit is working, the cutting teeth alternately contact the bottom of the well, the rock breaking torque is small, the contact area between the cutting teeth and the bottom of the well is small, the specific pressure is high, and it is easy to eat into the formation; the total length of the working edge is large, so the wear is relatively reduced. Cone bits can adapt to a variety of formations from soft to hard.
Our tricone bits are mainly used in oil well, water well, geothermal well drilling engineering. Roschen drilling bits are designed and manufactured according to the API & ISO standard which characteristics are long life, high drilling efficiency and low operation cost. We can produce bit sizes ranging from 2 7/8" to 26"and they can be applied to different formations from soft to very hard.
