ROTARY DRILLING TOOL BITS
The Sandvik range of rotary drilling bits includes geometries and cemented carbide grades for different surface and compressive strengths, abrasiveness, massiveness and homogeneity of rock as well as for various penetration rates and capabilities and characteristics of the drill rig. Innovative bearing technology and improved geometry, materials and machining methods provide longer bearing life. The selection of Sandvik rotary drill bits covers both blasthole bits for mining applications and bits suitable for construction and civil engineering applications. The product covers hole diameters from 159 to 406 millimeters (6 ¼ to 16 inches). Both air-cooled and sealed bearings are available, as well as various carbide grades and insert geometries with cutting structures optimized for all conditions.
RR910 & RR920 REMEDIAL SERVICE BITS
Sandvik RR910 family of drill bits are steel tooth type of bits that runs on an open bearing platform to provide cost effective and high performance drilling. The product line incorporates all of Sandvik’s design, manufacturing, and materials expertise to yield high quality and reliable performance. Cutting structure designs are based on proven configurations, for today's challenging downhole conditions.
RR441 ROTARY DRILLING TOOL BIT
Sandvik RR441, known as the Charger ™, revolutionizes the global mining market. A sealed journal bearing blasthole bit designed for surface mining. With up to 140% longer lifetime than comparable drillbits (RR222) and lower cost per meter we can offer a rotary bit that will pay off in the long run. Add to that, less bit changes and less manual handling. It´s Sandvik RR441, the real drill bit experience for the next generation. Computational fluid dynamic (CFD) optimized nozzles for optimal hole cleaning and superior wear life. Also improved durability dual seal journal bearing. Compressive stress induced (CSI) carbide that is harder and tougher. A hard faced heel row for longer cone steel life.
RR330 ROTARY DRILLING TOOL BIT
Sandvik RR330 revitalizes the global mining and drilling industry. With up to 45% longer bit life, RR330 outlives comparable drillbits on the market. Extended life is combined with improved ease of use and durability. Also with extended life you need less bit changes and less manual handling leading to improved safety. Sandvik RR330 has a simplified bit design with no air to the bearing. It has proven and optimized cutting structures, advanced wear protection features and optimized airflow to reduce wear and further extending bit life. Designed to ensure successful drilling in all conditions.
RR222 ROTARY DRILLING TOOL BIT
Through superior air flow and wear protection Sandvik RR222 will keep on working 20% longer than our previous version, RR221. Part of the upgrade has been the development of the new X05 cutting structure, delivering market leading penetration rates and bit life. New is also the MT-1, a mill-tooth bit offering maximum performance in soft rock applications.
Sandvik RR222 legs has been updated with opitimized air flow with the Sandvik asymmetrical leg. This improves the evacuation of cuttings – vital for continuous productivity – and improves wear life in abrasive or challenging drilling conditions.
