Roller Cone Bits
Roller cone bits are among the most widely utilized and versatile drilling tools in the oil and gas sector. These bits comprise three rotating cones, each fitted with cutting teeth that effectively crush and grind rock as the bit rotates.Mill-Tooth Bits: These bits feature steel teeth and are typically employed for softer geological formations such as shale or sandstone. The teeth are elongated and sharp, specifically engineered to penetrate easily into softer rock strata.Tungsten Carbide Insert (TCI) Bits: TCI bits are designed for more challenging formations. Rather than utilizing steel teeth, they incorporate tungsten carbide inserts, which exhibit exceptional hardness and wear resistance. TCI bits are particularly well-suited for drilling through hard, abrasive geological materials.
