Product Description

The 8-1/2" M433 7-blade PDC bit delivers higher ROP and durability through advanced cutter technology, dual cutter rows, and enhanced BHA vibration mitigation for hard and abrasive formations.

Features

·    Advanced 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.

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

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

·    FEA-Optimized Cutter 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.
