Roller bit is the most widely used drilling bit. When the roller bit is working, the cutting teeth alternately contact the bottom of the water well. It is mainly used for water well drilling in rock formation. Features 1. The drill bit size can be designed according to customers requirements. 2. Small rock breaking torque and small contact area of the cutting teeth and the well bottom. 3. The specific pressure is high, and it is easy to drill into the rock. 4. The total length of the working edge is relatively large, so the wear is relatively reduced. 5. The roller bit can adapt to a variety of formations from soft to hard.
The tricone bit is now widely used in geological exploration, oil field wells, water wells, coal mining, geological surveys,hydrological exploration, engineering piling, bridges, etc.| Basical Specification | |
