Drilling Bit

Key Features

1.Comprehensive Product Portfolio

We provide a full lineup of drilling bits including PDC bits, hybrid bits, bi-center bits, core bits, engineering bits and roller cone bits. With sizes ranging from 3 ¼" to 26", we deliver one-stop solutions for various well types and drilling applications.

2.Advanced R&D & Design

Equipped with professional IDS design system, we conduct optimized design on crown profile, cutter layout, hydraulic structure and force balance, ensuring reliable product performance through continuous technical upgrading.

3.Wide Adaptability to Complex Conditions

Our products are specially developed for soft, medium, hard, abrasive, plastic and interbedded formations. They work well for vertical wells, directional wells, horizontal wells, deep wells and rotary steering operations.

4.Standard & Customized Service

All products comply with IADC standards. Custom solutions on special dimensions, cutter types and structures are available to meet unique on-site drilling requirements.   

5.High Drilling Efficiency

Adopting high-performance cutters and optimized hydraulic design, the bits deliver high rate of penetration, improve cuttings transport and effectively prevent bit balling.

6.Excellent Wear & Impact Resistance

With reinforced gauge protection, strengthened leg back, rotary cutters and wedge cutters, the bits feature outstanding durability and long service life.

7.Stable Operation & High Safety

Low-torque and force balance design reduce stick-slip and eccentric movement. It ensures stable tool face control during directional and rotary steering drilling, minimizing downhole risks.

8.Diversified Functional Structures

Hybrid bits combine the strengths of roller cones and PDC cutters to reduce rock breaking energy. Bi-center bits realize effective hole enlargement. Core bits achieve high core recovery. Various optional structures for roller cone bits satisfy different working demands.

9.Superior Manufacturing Quality

Bearings, seals and cutting components are optimized and tested for long service. The overall structure features high strength and stable performance during continuous operation.
