Developed to meet the need for a more productive and longer lasting rotary drill bit, Sandvik RR221 is the latest update in the complete rotary blasthole bit range from Sandvik. Through comprehensive R&D expertise, Sandvik has made even greater advancements in the engineering of a more resilient bit designed to extend bearing hours — saving customers money, reducing safety risks and boosting productivity.
The new Sandvik RR221 series of drill bits runs on a patented, modularized air bearing platform, minimizing spalling during sustained loads and delivering 10-25% longer bearing hours and life increase of up to 30% compared with the previous generation Sandvik RR220 range. The result is significantly lower drilling costs.
“Today it is more important than ever for our customers to maximize the value of their investments, and Sandvik RR221 delivers,” says Simon Mitchell, Vice President Rotary Tools at Sandvik Mining. “Our latest tools feature
application-focused cutting structures and are more effective and hard wearing than their predecessors. They 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 improving penetration rates.”
Sandvik RR221 sizes range from 159 to 311 mm (6 ¼ to 12 ¼”) and rock hardness capability from 10 MPa to over 500 MPa. Now equipped with the patented Sandvik RR221 bearing, these bits offer high bearing hours and a low cost per drilled meter in a wide range of applications.
As a leading supplier to the mining industry, the full Sandvik offering of rock tools delivers the best combination for all blasthole drilling conditions. Highly trained, expert engineers from Sandvik are able to provide the right parts and service for safe operation, low operating costs and long service life.
