High-Performance Diamond Core Drill Bits Gain Ground in Southern Africa’s Mining Industry

Wuxi, China — Leading Chinese drilling tools manufacturer ROSCHEN is gaining significant traction in Southern Africa, where its Diamond Core Drill Bits are being used extensively in gold and mineral exploration projects across Zambia, Tanzania, and South Africa.

The NMLC Diamond Core Drill Bit from ROSCHEN is part of the company’s Ultramatrix (UMX) Series, offering optimized performance for both soft and hard rock conditions. Each bit is built to resist oxidation, reduce diamond pull-out, and deliver superior penetration rates.

Mining companies in Zambia and Tanzania have reported excellent results with ROSCHEN’s core bits, citing improved core recovery and cost savings on bit replacement. The company’s products are compatible with top hammer drill rigs and wireline triple tube core barrels, making them a preferred choice for gold exploration contractors and geotechnical engineers.

“In Southern Africa, drilling environments are demanding," said Mr. Li, Export Manager at ROSCHEN. “Our core bits are developed through years of testing in diverse rock formations — ensuring miners can drill deeper, faster, and with higher accuracy."

• Long bit life due to balanced diamond distribution
• Works seamlessly with NMLC and HMLC systems
• Reduced downtime in mineral exploration
• Certified under ISO and DCDMA standards

With strong partnerships across South Africa, Zambia, and Tanzania, ROSCHEN continues to expand its market footprint and deliver high-quality diamond drilling solutions that meet global standards.
