About this product

Product information from the supplier.

Our 17 1/2 Inches Matrix Body PDC Bits are engineered for high-performance drilling in challenging geological formations. Featuring a robust 6-blade configuration and precision-engineered 16mm cutters, this bit is designed to maximize Rate of Penetration (ROP) while maintaining superior directional stability and durability in oil and gas exploration.

Constructed from high-strength alloy steel with a specialized surface hardening process, these PDC bits offer exceptional erosion resistance. The combination of polycrystalline diamond composite cutters and a precision press-fit fastening method ensures maximum hardness and wear resistance, significantly extending the service life of the tool in demanding drilling environments.

Frequently Asked Questions

Q: What are the primary applications of PDC bits in the oil and gas industry?

PDC bits are primarily used for drilling through a wide range of rock formations, offering higher efficiency and speed compared to roller cone bits in soft to medium-hard formations.

Q: How do I optimize the WOB and RPM for a 17 1/2" PDC bit?

For this specific bit, the recommended WOB is 30-180 KN and RPM is 60-250 r/min. It is critical not to use the upper limits of both parameters simultaneously to avoid premature tool failure.

Q: What is the difference between a Matrix Body and a Steel Body PDC bit?

Matrix bodies are generally more resistant to erosion and abrasion, making them ideal for highly abrasive formations, whereas steel bodies offer higher impact resistance.

Q: Can these bits be used in HDD (Horizontal Directional Drilling) applications?

Yes, while designed for oil and gas, the PDC technology is highly effective in HDD and construction drilling where hard rock reaming is required.

Q: What is the purpose of the surface hardening process on the bit crown?

The surface hardening process is applied to the crown to protect the body from hydraulic erosion caused by high-velocity drilling fluids.

Q: How do the 16mm cutters improve drilling performance?

Larger 16mm cutters provide a more aggressive depth of cut and better heat dissipation, which is essential for maintaining speed in larger hole diameters like 17 1/2".
