The Sandvik RR440 range of rotary bits has remained the benchmark for drilling excellence for 15 years. The launch of Sandvik RR441 is designed to help bring the drilling industry into the future. As a new and improved version of its predecessor RR440, the RR441 provides excellent class-leading bearing life, simplification of the bearing system, improvements in air flow and superior wear protection in soft rock applications.

“Today it is more important than ever for our customers to maximize the value of their investments, and Sandvik RR441 delivers,” says Simon Mitchell, Vice President Rotary Tools at Sandvik Mining and Rock Technology. “Our latest range of rotary blasthole bits features advanced cutting structure design for optimal bottom hole coverage and maximum penetration rates. The bits have better longevity thanks to multiple design improvements, where we have matched our proprietary Sandvik cemented carbide shapes and grades to specific drilling conditions. This will help to reduce wear and breakage, further increasing bit life and provide an easier to use product.”
