"Today it is more important than ever for our customers to maximise the value of their investments, and Sandvik RR441 delivers," said 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."
Sandvik RR441 sizes range from 171mm to 406mm (6-¾ to 16in). Now equipped with an improved durability dual-seal journal bearing.
