Product Description

The 12-1/4" M423 7-blade PDC bit features 110 φ16mm cutters with dual-row layout, FEA/FBS-optimized cutting structure, and spiral blade design — delivering high ROP, durability, and BHA vibration mitigation for hard formation drilling.

Features

·    Advanced PDC cutter Technology: Improving cutting efficiency and increasing ROP and durability — cutters stay sharper longer.

·    7 Blades + Dual Cutter Rows: Extend bit life and improve penetration efficiency with 110 φ16mm cutters.

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

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

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

·    Force Balance Software (FBS): Optimizes cutter axial/radial angles for stronger aggressiveness and durability.

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

·    Spiral Blade Design:Effectively improves bit stability and ROP.
