Product Description

The 12-1/4" S423 5-blade PDC bit features triple mixed cutters (φ13/φ16/φ19mm) and dual-row layout, with FBS-optimized cutter angles for superior aggressiveness, durability, and interbedded lithology performance.

Features

·    Triple Mixed Cutter Sizes – φ13 / φ16 / φ19mm: Strategically combines three cutter sizes for optimal performance across variable formations.

·    Dual Row Cutter Layout: Extends aggressiveness and durability compared to single-row designs.

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

·    Interbedded Lithology Advantage: Provides multiple advantages in interbedded formations with mixed 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: Reduces NPT and improves overall drilling efficiency.

·    DOC Optimization: Calculated from field experience for rational formation penetration.

·    Spiral Blade Design: Effectively improves stability and ROP.
