Hardfaced head bearing surface ensures durability during high-speed rotary drilling.
Tungsten carbide inserts reduce wear in abrasive formations.
Enhances gauge protection and increases bit stability and lifespan.
Premium carbide inserts resist breaking and abrasion.
Extends the operational life of the cutting structure.
Equipped with three jet nozzles for efficient fluid distribution.
Robust construction maximizes flow capacity and improves drilling performance.
Seal and Lubrication: The bearing seal is adapting the high quality HNBR O-ring. The best seal compression and the radial seal structure can enhance the seal performance. The compensation system and the high quality bit grease can limit pressure differential, and greatly increase the lubricating reliability.
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
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
Adaptability Across Formations: Performs well in soft to medium formations like mudstone, gypsum, and soft limestone.
Efficiency: High ROP in softer formations reduces drilling time and costs.
Durability: Enhanced materials and design extend operational lifespan and minimize downtime.
Customizability: Tailored teeth or inserts ensure optimal performance in varying geological conditions.
High Performance in Abrasive Formations: Tungsten carbide hardfacing and premium inserts deliver consistent results in demanding environments.
Drills effectively through formations such as sandstone, shale, and limestone.
Excels in complex formations unsuitable for other bit types.
Efficient for sand, gravel, and bedrock formations.
Achieves high ROP in softer formations for cost-effective operations.
Suitable for drilling test holes or cores for minerals, metals, and other resources.
Reliable in diverse terrains, providing valuable geological data.
Industry-standard packaging ensures safe transportation and product integrity.
Customizable options available for specific drilling needs.
Expert technical support for enhanced bit performance.
