Sandvik introduces its most durable rotary drill bit

Sandvik Mining and Rock Solutions is introducing its next generation drill bit for rotary drilling at MINExpo INTERNATIONAL® 2021 in Las Vegas. The Charger™ RR450 can achieve up to a 90 percent increase in bit life compared to other premium sealed bearing bits.

The Charger™ RR450 rotary drill bit is Sandvik’s most durable to date. It is designed to maximize customers’ drilling uptime, increase penetration rate and improve safety, thanks to fewer bit changes and reduced operator interactions. The new bit features Sandvik’s most powerful carbide range, PowerCarbide™, as well as new cone steel protection, computer optimized cutting structures and the patented Charger™ sealed journal bearing system. Testing shows that bit life can be increased by up to 90 percent while maintaining the same high penetration rates.

“Charger™ RR450 is truly a leap forward for our rotary bit offering,” said Carsten Mijic, Product Manager for Rotary Bits at Sandvik Mining and Rock Solutions. “We can now offer our customers nearly double the bit life compared to other premium sealed bearing bits. This can translate into hundreds of thousands of dollars saved, while at the same time reducing the need for operator interactions with the bit and drill deck.”

PowerCarbide™ SH75: the key to excellence

A key reason for the improved bit life of Charger™ RR450 is the inclusion of the PowerCarbide™ SH75 grade, part of Sandvik’s most advanced cemented carbide range. The self-hardening carbide grade can improve bit life by up to 50 percent in abrasive rock conditions.

“Earlier this year, we introduced the PowerCarbide™ SH75 grade to our rotary drill bit offering with the launch of the Sandvik RR240 air bearing bit range,” said Mijic. “It performs incredibly well, and we are pleased to be able to now include it in our ultra-premium sealed bearing bit offering. It is state-of-the art in its qualities, and very well suited for many of our customers’ challenges.”

The new Charger™ RR450 bit is available today in sizes ranging from 9 to 12 1/4 inches. Additional sizes and types will become available in the near future.
