Product Description

The 8-1/2" S223 3-blade PDC bit delivers 53% higher blade standoff than matrix bits, maximizing junk slot area for superior cuttings evacuation, cooling, and anti-balling — with dual row cutters maintaining high ROP and durability.

Features

·    3-Blade Design – Maximized Junk Slot Area: Three blades provide the sharpest and largest junk slot area, significantly improving cuttings evacuation, cleaning, cooling, and reducing bit balling risk.

·    53% Higher Blade Standoff vs Matrix Bits: Advanced GS-series engineering delivers 53% higher blade standoff without sacrificing blade durability — resulting in greater open face volume for faster ROP and better hydraulics.

·    Dual Row Cutters – Maintaining Aggressiveness: Despite only 3 blades, the dual row cutter layout achieves high drilling efficiency without sacrificing aggressiveness.

·    Multi-Optimized Force Balance: Optimized cutting structure increases bit stability and cutting efficiency during drilling.

·    Dynamic Flow Simulation Technology: Used for hydraulic design — optimizing nozzle quantity and placement to ensure optimum bottom hole flow patterns and anti-balling performance.

·    Advanced Hardfacing Material: Enhanced abrasion resistance and erosion resistance for longer bit life.

·    Advanced GRT-Series Cutters: Premium GRT-series cutters endure frictional heat generated during drilling. Improved abrasion resistance maintains a sharp drilling edge for higher ROP.
