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.
Use range:
The combined cone drill bit is suitable for drilling machine-filled rock, drilling water wells and ventilation holes. It is suitable for strong, medium and light weathered rock and gravel, such as granite, gneiss, sandstone, limestone, shale, etc.
The combined cone bit has the following characteristics:
1. Use the principle of hydraulics to remove the sediment at the bottom of the hole;
2. The domestic first double fulcrum cone;
3. Anti-wear mechanism of palm back;
4. Unique and reasonable tooth wheel distribution;
5. Protective cylinder protection block further enhances the stability of the drill bit and prolongs the life of the drill bit.
