Product Description

The 11-5/8" M223 5-blade PDC bit features a tungsten carbide matrix body with 20% improved erosion resistance, large φ19mm dual-row cutters, and FEA/FBS-optimized cutting structure — delivering superior durability and performance across medium and interbedded formations.

Features

·    Advanced Tungsten Carbide Matrix Body: 20% improvement in erosion resistance compared to previous matrix bits — less cutting structure and bit body damage.

·    Large φ19mm PDC cutters: Largest cutter size in the series — provides aggressive penetration and high ROP.

·    Dual Row Cutter Layout: Extends aggressiveness and durability.

·    Interbedded Lithology Advantage: Provides multiple advantages in interbedded formations with variable hardness.

·    Enhanced Bit Stability: BHA shock and vibration mitigation for smoother drilling.

·    Anti-Balling Design: Increase cleaning and reduce balling in sticky formations.

·    Advanced PDC Cutter Technology: Perfect performance on impact strength resistance and abrasive resistance.

·    FEA-Optimized Cutter Layout: Optimized distribution and layout reduces NPT and improves drilling efficiency.

·    FBS-Optimized Cutter Angles: Optimized in both axial and radial directions for stronger aggressiveness and durability.

·    DOC Optimization:Depth of cutters calculated from field experience for rational formation penetration.
