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.



Features


CFD hydraulic balance design, ensures optimal bottom hole flow pattern and anti-balling.

Optimize the cutting structure and places high quality cutters at different points, increases wear resistance and offensive of the bit.

• Anti-whirl design improves ROP and enhances drilling stability of the bit.

• The surface of the blade is welded by wear-resistant hardfacing material, improves wear resistance and erosion resistance of bit
