A tricone bit is a drill bit with a head that is divided into three main parts. Thetricone bit consists of three rotating cones working inside each other and each with its own row of cutting teeth.
When using this tricone drill bits product, it needs to be installed on the cone drill. The power generated by the tricone bits drill head produces a rapid rotation of the bit, and then slowly drills into the stratum and objects. With the hardness of the tricone rock bit plus the speed of rotation, the tricone bit for drilling speed will be shaped. A very large bit pressure, then the bit pressure will have a crushing effect on the object, whether rock or clay or other objects will be dispersed to the outer layer with the rotation of the bit, and then a well will be formed. When the bit is used for work, it can be completed not in one operation, but in one operation. Use time, then stop to check and operate.

7 1/2 inches is a regular size in water well drilling, it is working well with small capacity drilling rigs and widely used in the world.
Steel tooth tricone rock bit is also named milled tooth tricone rock bit could drill soft mudstone, even soft limestone, the cones are hard faced by tungsten carbide, the bearing is journal and locked by ball, high grade elastomer(rubber)-HNBR O-ring sealed bearing, grease compensating system lubricate the bearing , the working life is very long.
