Tungsten Carbide Insert(TCI) Tricone Bits
1: with dome shaped tungsten carbide inserts on the gage rows and chisel shaped inserts on the inner rows for best performance in tight and well cemented medium hard to hard formations such as abrasive limestone, sandstone and dolomite where maximum gage wear resistance is required. Ample hard facing is applied to the shirttail providing maximum protection against abrasion and insures the longest possible bearing life. S ested operating weights are 1,500 to 6,000 pounds per inch of bit diameter, while rotary speeds of 140 to 55 RPM give best performance. Rotary speed should be decreased as the weight is increased. Near the bit stabilization is also recommended for maximum bit life.
2:designed to provide a fast rate of penetration, high durability and long bit life. Each bit design represents a unique effort to provide the right selection of insert size, spacing, shape, hardness, protrusion, and material selection for use in different types of rock formations. insert bits give optimum results in the field by eliminating tracking and off center rotation.a wide variety of types of chisel, conical and spherical shaped tungsten carbide inserts, each uniquely designed for drilling in specific types of rock formations.
