Targeting construction pain points in open‑pit mines such as soft rock, frequent faults, and unstable broken rock mass, our company has developed a special PDC diamond scraper bit belong to a new PDC Bit for open‑pit drilling and blasting. It has completed field tests in mining areas of Xinjiang and multiple overseas open‑pit mining projects, winning high recognition from customers with its outstanding overall performance. Here are some production about our PDC drill and PDC Bits.
Diamand PDC bits are specialized PDC drilling tools with polycrystalline diamond compact (PDC) cutters as the main cutting body. It shears and cuts rock formations via PDC cutter. Different from traditional down‑the‑hole bits and tricone bits, they are suitable for blast‑hole drilling in open‑pit mines and feature universal adaptability to all strata.
Traditional Drill Bits show prominent shortcomings in fractured and complex formations: down‑the‑hole bits are prone to shank fracture and scrapping, while tricone bits suffer rapid wear and short service life. Our PDC bit effectively addresses these industry pain points, delivering greatly improved drilling efficiency and single‑bit footage. Equipped with alloy gauge strips, PDC gauge protection, hybrid gauge design, double‑row cutter layout and other structures, it features wide formation adaptability, lower overall wear rate, and consistent borehole diameter in long‑term drilling operations.
The product adopts high‑grade brazing technology, ensuring tight bonding between PDC cutters and the steel body with high shear resistance. It resists cutter loss and chipping even under strong vibrations when drilling fractured rock formations.
Manufactured entirely with high‑precision CNC equipment, it features high processing efficiency, consistent dimensional accuracy and mechanical properties, enabling stable mass supply.

This series of PDC bits features a threaded connection structure, which can be directly connected to Drill Rods or assembled with drill rod adapters. The matching Drifter Rods adopt tapered female joint compliant with API standards, compatible with large‑diameter drill rods, capable of withstanding high torque output, and suitable for mainstream open‑pit rock drilling rigs on the market.

Field application data shows that after replacing traditional drill bits, bit‑replacement frequency at mining sites has decreased significantly. The overall construction costs including rig downtime, labor and spare parts have been greatly reduced, with better borehole forming quality, effectively improving the overall construction efficiency of open‑pit drilling and blasting. Moving forward, our company will continue to optimize product structures and launch customized models for segmented working conditions, providing high‑efficiency and durable drilling solutions for open‑pit mines worldwide.
