API standard 3 7/8 IADC 127 steel tooth tricone bit

TCI rotary bits allow for drilling in hard, abrasive formations such as homogeneous limestone, basalts, granite and chert, as well as softer formations such as shales, clays and sand. The arrangement and design of our top-of-the-line tungsten carbide inserts help provide maximum durability, reduce drill vibration and allow greater drilling weights and effective hole cleaning in consolidated and unconsolidated formations. Thompson's TCI Bits will help drillers achieve maximum penetration rates.
