API Metal sealed oilwell tricone drill bit for hard foratmions
Product Description
A tricone bit is a drill bit with a head that is divided into three main parts.The tricone bit consists of three rotating cones working inside each other and each with its own row of cutting teeth.
When using this tricone bit, it need to be installed on the cone drill.The power generated by the tricone bits drill head produces a rapidrotation of the bit, and then showly drills in to the stratum and objects.With the hardness of the tricone bit plus the speed of rotation, the tricone bit for drilling speed will be shaped.A very large bit pressure, then the bit pressure 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.
