Excellent Cuttings Removal
Three-wing drag blade structure ensures smooth cuttings evacuation, preventing bit balling and cuttings regrinding.
Durable & Reliable Performance
High-quality PDC diamond cutters provide excellent impact resistance, uniform wear, and extended service life.
Wide Compatibility & Customization
10+ standard sizes available, compatible with mainstream thread types, fully customizable upon request.
Product Overview
The Three Wing PDC Drag Bit is a high-efficiency rotary drilling bit specifically designed for soft to hard rock formations. By combining a streamlined three-wing blade structure with highly wear-resistant PDC diamond cutters, this bit achieves an ideal balance between penetration speed, drilling stability, and cost-effectiveness.
It performs exceptionally well in complex formations such as red sandstone, mudstone, coal seams, shale, slate, marble, and backfill layers, making it widely used in coal mine safety, infrastructure construction, water well drilling, and geothermal projects.
Design & Performance Features
High-Efficiency Rock Cutting
Three-wing streamlined blade layout with densely arranged PDC cutters enables shear-type rock breaking, significantly outperforming traditional drag bits in soft formations.
Smooth Cuttings Removal
Large junk slots and optimized hydraulic design ensure cuttings are rapidly removed from the borehole, keeping the bottom clean and preventing bit clogging.
Excellent Directional Control
Reinforced bit body and gauge protection provide superior guidance during spudding and drilling, helping maintain verticality and reduce hole deviation risk.
Wide Formation Adaptability
Designed for formations with Protodyakonov hardness coefficient F1-F<8, ideal for coal seams, mudstone, shale, sandstone, limestone, and other soft to hard formations.

Operating Guidelines & Tips
Spudding Recommendation
When drilling in loose or complex surface layers, apply moderate weight on bit with higher RPM to ensure smooth spudding and accurate guidance.
Drilling Parameters
High penetration rates are achievable in soft formations, but proper matching of WOB and RPM is essential to protect both bit and borehole quality.
Flushing & Cooling
Ensure sufficient air or mud flow to effectively cool PDC cutters and evacuate cuttings.
Casing Drilling
When used as a casing bit, select the bit size according to the outer diameter of the casing.
