The TCI (Tungsten Carbide Insert) Tricone Bit is engineered for the most demanding drilling environments, specifically targeting medium-hard to extra-hard formations such as granite, chert, and abrasive sandstone. Instead of milled teeth, this bit features high-strength tungsten carbide inserts that are press-fitted into the cones, providing superior hardness and impact toughness. Its advanced bearing technology and reinforced shirt-tail protection ensure maximum durability during prolonged high-pressure operations, effectively reducing the frequency of bit replacements in deep-hole projects.
Key Highlights
Extreme Durability: Premium tungsten carbide inserts are designed to crush and fragment the hardest rock with minimal wear.
High-Load Bearing System: Incorporates a heavy-duty, sealed bearing system capable of handling high weight-on-bit (WOB) for extended periods.
Advanced Gauge Protection: Reinforced with carbide inserts on the gauge area to maintain a consistent borehole diameter in abrasive environments.
Superior Service Life: Built for reliability in oil & gas exploration, geothermal drilling, and mining where reducing "trips" (bit changes) is critical.
The TCI (Tungsten Carbide Insert) Tricone Bit is the ultimate heavy-duty tool for medium-hard to extra-hard formations.It utilizes high-strength, impact-resistant tungsten carbide inserts that are strategically arranged to provide full-bottom coverage and efficient rock crushing.The bit body features an enhanced shirt-tail and leading-edge protection, often reinforced with diamond or carbide inserts to resist erosion in abrasive environments.Our TCI bits also incorporate an advanced pressure compensation system and a proprietary grease reservoir, ensuring that the critical bearing components are continuously lubricated even under extreme downhole pressures.
