Product Description

^{Specialty Steel for API Standard}

Our drill bits are crafted from 4145H High-Performance Steel.

The 4145H high strength steel possesses excellent mechanical properties and Hardness Up to HRC50, ensuring drill bits have ample toughness and compression resistance.

With superior wear resistance, 4145H steel lasts Over 30% Longer than conventional materials, allowing for more durable drill products.

Innovations for Superior Performance

The Secondary Rows of Teeth regulate the cutting volume to protect the main teeth from premature wear, Ensuring Cutting Stability.

Superior Arc-Shaped PDC Composite Gauge protects against abrasion, enhancing durability and stability.

The Double Rows of Teeth and 6 Blades - four long, two short - greatly enhance drill stability.

The surface of the blade is welded by wear-resistant Hardfacing Material to boost abrasion resistance and durability.
 

Innovative Geometry for Directional Drilling

Our Short Parabola Design optimizes the bit surface area to balance wear reduction and drilling performance.

This geometry Improves Service Life and drilling ability in deviated and directional wellbores.

The shortened parabolic profile Reduces Frictional contact area for less wear. Balanced Contact forces maintain weight on bit for continued cutting efficiency and stability during lateral drilling. 

This careful design demonstrates our commitment to creating drill bits tailored for your specific drilling objectives.

Optimized Flushing for Efficient Drilling

Our drill bits feature an innovative 6-Hole Waterway design that enhances chip removal and reduces clogging.


The optimized layout improves drilling hydraulics for Faster Cuttings Evacuation.


The single-row, six-blade design with an inner cone Limiting Cutter reduces torque and enhances directional control.
