Four-Wing PDC Arc-Angle Oil Drill Bit (Multi-Formation Adaptable · Water/Air Drilling Compatible)
Tungsten Carbide Body
Spiral Design
Multi-Formation
The Four-Wing PDC Arc-Angle Oil Drill Bit features a die-cast integrated tungsten carbide alloy steel body combined with a four-wing arc-angle cutting structure and spiral design. With exceptional body strength, superior wear resistance, and efficient water/cuttings removal capability, this bit can be paired with functionally specific PDC cutters according to different formation characteristics, comprehensively meeting drilling requirements from soft to hard formations. Suitable for open-pit mining, slope support, water wells, geothermal drilling, and compatible with both water and air drilling methods for efficient and stable hole opening, significantly reducing construction costs.
Widely used in open-pit mining blast hole drilling, anchor cable hole drilling, slope reinforcement drilling, support engineering drilling, foundation pit construction drilling, water well drilling, shallow geothermal drilling, and other scenarios. Particularly suitable for fractured formations and multi-type drilling process requirements.
Core Advantages
Tungsten Carbide Alloy Steel Body · High Strength & Wear Resistant
The body is made of tungsten carbide alloy steel through die-cast integrated forming process, featuring tight structure without splicing seams. Strength far exceeds ordinary steel bodies with excellent wear resistance, impact resistance, and deformation resistance. Can withstand grinding and impact from fractured formations, significantly extending bit service life, reducing bit change frequency, and minimizing construction downtime.
Four-Wing Arc-Angle Design · Impact Resistant & Anti-Chipping
Unique four-wing arc-angle cutting structure effectively buffers impact loads from fractured formations, significantly reducing risks of PDC cutter chipping and blade breakage. Particularly adaptable in fractured hard formations like granite. Four-wing symmetrical distribution ensures even force distribution during drilling with minimal radial vibration, providing excellent hole stability.
Spiral Design · Efficient Water & Cuttings Removal
Spiral blade and cuttings removal channel design enables rapid water drainage and cuttings removal during drilling, preventing cuttings accumulation and mud blockage. Reduces risks of bit balling and sticking. Suitable for both water drilling (mud/clean water circulation) and air drilling (air cuttings removal), ensuring continuous drilling operations and improving hole opening efficiency.
Flexible PDC Cutter Selection · Universal for Soft to Hard Formations
Can be paired with corresponding functional PDC cutters according to different formation characteristics: High-efficiency cutting cutters for soft formations (mudstone, backfill soil), wear-resistant cutters for medium-hard formations (sandstone, limestone), and impact-resistant cutters for hard fractured formations (granite fractured layers). Comprehensively meets drilling requirements from soft to hard formations with exceptional adaptability.
Water & Air Drilling Dual Compatibility · Flexible Construction
Breaks single drilling process limitations – compatible with both water and air drilling methods, adapting to different construction scenarios and site conditions. Water drilling adapts to wet formations requiring cooling and cuttings removal, while air drilling suits dry, water-scarce environments. No need to change bit models, significantly improving construction flexibility and reducing equipment adaptation costs.
Four-Wing Symmetry · Smooth Hole & High Efficiency
Four-wing symmetrical cutting structure ensures balanced drilling speed and smooth, polished hole walls, eliminating need for subsequent hole finishing. Suitable for open-pit mining blast holes, anchor cable holes, and other scenarios requiring basic hole wall quality. Achieves over 20% faster drilling speed compared to similar bits, meeting large-scale rapid hole opening requirements.
Applications
Suitable Formations
Various formations from soft to hard including sandstone, backfill soil, mudstone, limestone, granite (fractured layers), particularly adaptable to fractured formations.
✅ Compatible with both water and air drilling methods, adapting to different construction processes and site conditions.
Not recommended for ultra-hard intact formations with F＞11 (such as intact granite) and highly abrasive extreme formations.
Drilling Method
Rotary Drilling (Water & Air Drilling Dual Compatible)
Water Drilling Use: Use with mud or clean water circulation, utilizing spiral design for efficient water drainage and cuttings removal, ensuring bit cooling, and improving wear resistance and hole opening efficiency.
Air Drilling Use: Use air circulation for cuttings removal, suitable for dry, water-scarce environments. Control drilling pressure and rotation speed to avoid bit overheating and ensure stable drilling.
