Competitive Price for Pdc Oil Drill Bit - Tricone bit517 – Ruishi

1. Motor hardfacing: Tungsten carbide particle hardfacing is applied liberally along the shirttail and extended up the leading edge of the bit leg for additional protection in high-speed, directional or abrasive applications. 2. Six-point Gauge Stability: The design delivers near six-point contact with the borehole wall for unequalled bit stability that protects the cutting structure from damaging lateral blows. 3. G-Gauge protection: more tungsten carbide inserts are placed in the gauge to reduce the wear in the abrasive formation. It can protect gauge and increases the stability and life of the bit. 4. Cutter: premium carbide teeth having increased resistance to breaking and abrasion , maximum increase cutting structure operating life. 5. Nozzle:These nozzles are much sturdier and provide greater flow capacity and maximize fluid distribution to the cones. Application: Suitable for soft formation with low compressive strength and high drillability ,such as mudstone,gypsum and soft limestone,etc.
