PDC Core Drill Bit
Wireline Coring | DCDMA Standard
🔷 Product Overview
Our PDC Core Drill Bit is designed for wireline coring applications, widely used in mineral exploration, geological drilling, and water well projects. Equipped with high-quality polycrystalline diamond compact (PDC) cutters, the bit delivers fast penetration, high core recovery rate (up to 95%), and long service life in soft to medium-hard formations. Available in BQ, NQ, HQ, PQ and PQ3 sizes, fully compliant with DCDMA standards, ensuring global compatibility.
High Core Recovery (≥95%)
Superior core integrity and recovery rate for accurate geological data.
3–5x Faster Drilling Speed
Compared to impregnated diamond bits – dramatically reduces project time.
Premium PDC Cutters
1308/1613/1913 cutters for superior wear resistance and long lifespan.
Stable Hole Quality
Optimized blade layout ensures straight drilling and minimal deviation.
Optimized Hydraulic Design
Efficient cuttings removal, anti-balling, and better cooling.
Wireline Coring Compatible
Fully compatible with standard wireline systems for fast core retrieval.
📌 Applications
Ideal for soft to medium-hard rock formations including shale, sandstone, limestone (f = 3–10). The shear-cutting action of PDC ensures high ROP and excellent core quality, making it the preferred choice for exploration drilling worldwide.

🔧 Bit Structure & Shearing Principle
Design Highlights
- PDC cutters mounted on crown for efficient shearing action
- Optimized blade layout for smooth cutting and reduced torque
- Reinforced gauge protection maintains hole diameter
- Wide fluid channels for efficient cleaning and cooling
- Shear rock breaking principle → much faster than grinding
💡 How PDC Shearing Works:
Unlike impregnated bits that grind rock, PDC cutters shear the formation. This results in 3–5x higher penetration rates, less energy consumption, and superior core recovery. The arc crown and optimized blade geometry further enhance stability in wireline applications.
