Sandvik introduces the new RR441 rotary bit with an advanced cutting structure design. The RR441 is an improved version of the RR440, designed to last up to 140% longer than comparable rotary bits*. With an extended bit life and fewer bit changes, the RR441 maximizes drilling uptime, providing a lower cost per meter and setting a new industry standard.
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.
“Our latest range of rotary blast hole 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 (6¾in to 16in). Now equipped with an improved durability dual seal journal bearing.
As a leading supplier to the mining industry, Sandvik continues to drive the mining industry forward, always offering a full drill string from top to bottom with high-quality drilling tools, designed for excellent reliability, performance and longevity. The Sandvik RR441 is developed according to three main principles, each of which provides a distinct benefit; reliability, application-focused cutting structures and a complete, combined offering.
