Our PDC bits are designed with newer abrasion-resistant cutters, and bit designs matched to your specific project lower drilling cost with
1.higher average ROP
2.greater stability
3.greater durability
4.Greater efficiency
Drill longer:
Our engineers developed a group of cutters for the specific wear issues you encounter. This is the
optimum balance between cutter durability and cutter effectiveness with a lower probability of fracture.
PDC bit Specifications
1. High wear resista nce cutters.
2. Oppose-circumnutation design.
3. suitable for medium to hard formation

Hole openers are used to enlarge the diameter of a pre-drilled hole. They are custom built to specification, and come in a wide variety of sizes. A hole opener is sometimes referred to as a reamer.
Roller cone hole openers are specifically designed for horizontal, rock drilling applications. Extensive tool performance experience combined with the pooling of hole opener expertise from various industries (directional crossing, mining and oil field) has aided in designing and manufacturing a proven line of horizontal hole openers for the trenchless construction industry. Our approach to tool application analysis and tool set-up recommendations includes cutting structure selection, hydraulics and torque and drag analysis. This comprehensive approach enables us and the contractor to minimize the number of reaming passes and optimize hole opener performance.

Tricone Roller Bits
All sizes and IADC codes of drill bits are available. Special requirements of different models can be customized.
1)Main features
1. Cutting Structure of this type sealed and non-sealed tci tricone bits:
The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit.
2. Gauge Structure of this type tci tricone rock bits:
Multiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.
3. Bearing Structure of this type tci tricone rock bits:
High precision roller bearing with two thrust faces. Ball lock the cone. Thrust faces hardface with wear resistant alloy. Abrasion resistance and seizure resistance of the bearing are improved.
