Tricone Roller 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 torque of breaking the rock is small, the contact area between the cutting tooth and the bottom of the well is small, the specific pressure is higher, and it is easy to eat into the formation; the total working length of the working blade is large, thus relatively reducing the wear. Roller bit can adapt to a variety of formations from soft to hard.
According to the number of cones, it can be divided into single-cone bit, tri-cone bit, and assembled multi-cone bit. According to the cutting material can be divided into steel teeth (milled teeth) and insert tooth bit.
