Tungsten Carbide Insert(TCI) Tricone Bits
1: efficient drilling of soft to medium formations such as shale, red bed, limestone and other strata of low compressive strength with hard streaks or abrasive properties. This design employs a maximum offset and features all chisel shaped tungsten carbide inserts which are spaced slightly farther apart than normal to insure the highest possible rate of penetration. Ample hard facing on the shirttail provides maximum protection against abrasion and insures the longest possible bearing life. Suggested operating weights are 1,000 to 3,000 pounds per inch of bit diameter with corresponding rotary speeds of 200 to 50 RPM.
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.
