Product Description

Product Description

Our mine core drill bit is suitable for mineral exploration, underground and open-pit mining. We offer standard sizes: 65mm, 75mm, 94mm, 113mm, 133mm, 153mm, 173mm, plus customized sizes for specific needs. All sizes meet industry standards, with high dimensional accuracy, compatible with mainstream mining rigs.

Small sizes (65mm,75mm) for shallow exploration;

Medium sizes (94mm,113mm) for routine tasks; 

Large  size(133mm+) for deep, large-scale mining.

Product Advantages

• High Core Recovery: Over 90% stable recovery rate, intact core to provide reliable geological data for mineral exploration.

• Super Wear Resistance: Made of high-strength wear-resistant PDC/hard alloy teeth, service life 30%-50% longer than traditional bits, reducing replacement frequency and costs.

• Efficient Drilling: Streamlined structure and precise flow channels ensure fast chip removal, 25%-40% higher efficiency, no jamming, stable for continuous operation.

• Wide Adaptability: Customizable (diameter, tooth type, matrix), compliant with API/industry standards, compatible with mainstream rigs for open-pit, underground mining and exploration.

• Safe & Durable: Reinforced structure reduces fracture and tooth loss risks, stable in complex conditions, ensuring safe and efficient drilling.
