TCI Tricone Bit IADC 417/427/437 for Soft Formation Drilling
The TCI Tricone Bit with IADC 417/427/437 is a rotary roller cone drilling tool specifically designed for extremely soft formations with low compressive strength and high drill-ability. Typical formations include mudstone, clay, chalk, gypsum, salt rock, soft shale, soft limestone and similar soft rock strata.
Featuring TCI (Tungsten Carbide Insert) cutting structures on three rotating cones, this tricone bit progressively crushes and fractures soft rock at the bottom of the borehole for efficient penetration. The recommended operating parameters are WOB 0.35-0.9 KN/MM and rotary speed 140-70 r/min, providing stable and effective drilling performance in soft ground conditions.
The bit is supplied by Brighttop Global Co., Ltd and can be customized in diameter, bearing configuration and connection specification to match different drilling rigs and hole requirements.
