High-Efficiency PDC Drill Bits for Any Drilling Environment

Steel Body PDC Drill Bits

Steel body PDC Bits feature a drill bit body machined from a single piece of alloy steel. The cutters are manufactured by welding PDC (polycrystalline diamond compact) segments onto tungsten carbide studs, which are then mounted onto the bit body. The gauge section of the bit body is also embedded with diamond blocks or other wear-resistant materials.

Steel body PDC drill bits are designed for fast and efficient drilling in soft to medium formations with high compressive strength and absence of bottom-hole gravel. Their wide flow channels facilitate efficient cuttings removal.

Additionally, steel-body PDC bits are primarily used for drilling through gravel-laden formations and hard, high-compressive-strength formations that are challenging to penetrate.

Hybrid PDC Drill Bit

The hybrid drill bit employs a combined cutting mechanism, first fracturing formations with roller cone cutters, then shearing through rock with PDC blades, effectively protecting the PDC cutters. Compared to conventional PDC drill bits, they offer superior drilling stability and achieve higher ROP (Rate of Penetration) in both soft and hard interbedded formations.

The hybrid drill bit consists of both roller cone and PDC cutters, fully integrating the strengths of both drill bit type.

• The PDC cutters enable faster ROP at lower WOB (Weight on Bit).
• Conical roller section reduces drillstring vibrations, enhancing performance in hard rock formations.
