Boart Longyear, the global leader in exploration drilling equipment and tooling, has announced the release of its newest diamond bit innovation: the Stingray™ DHM/full face diamond bit. Designed and manufactured in the US for downhole motor (DHM) and full-face drilling, the Stingray bit “combines cutting-edge crown design with durable diamond technology to maximise penetration rates and extend bit life across the most challenging ground conditions.”
The Stingray bit is the result of extensive field testing and development, addressing the demand for higher efficiency, longer service life, and greater reliability in abrasive and variable geology. “Its advanced design delivers more consistent wear across the bit face, reducing downtime and enabling drillers to reach target depths faster and more safely.
“Stingray represents the next generation of diamond drilling technology,” said Jon Peterson, Product Manager, Diamond Products. “By pairing aggressive cutting structures with Boart Longyear’s proven diamond technology, we’re giving contractors and mine operators a tool that not only improves performance, but also drives real savings in time and cost.”
Key features and benefits include an optimised crown geometry engineered for high RPM downhole motor and full-face applications; plus an even wear profile – dual-matrix face and strategic diamond placement help limit concave wear, ensuring maximum crown utilisation.
Increased productivity comes from higher penetration rates and fewer bit changes reducing non-productive time. Boart also says it offers versatility as it performs in abrasive formations with high quartz content, fractured zones, and variable clay bands.
The bits are designed and manufactured in the US under Boart Longyear’s rigid quality standards and join Boart Longyear’s growing portfolio of drilling solutions designed “to improve safety, efficiency, and performance in exploration and mining operations worldwide.”
