Product Description
393.7mm IADC537G TCI Tricone Drill Bit for Water Well Drilling
The IADC537G TCI tricone drill bit is engineered for superior performance in water well drilling applications. With its advanced bearing system and optimized tooth configuration, this 393.7mm (15 1/2") bit delivers exceptional drilling efficiency and extended service life.
Key Features & Benefits
- Center jet design prevents balling formation and accelerates drilling cuttings removal
- High saturation NBR bearings reduce sealing pressure and enhance reliability
- G-Gauge protection improves measuring accuracy and extends bit lifespan
- Additional tooth row between rear taper and outflow trims borehole and protects cones
