The innovative single-sealed roller-bearing technology and optional Sandvik PowerCarbide® inserts ensure reliable and efficient drilling with 45% longer service life and lower drilling costs for the RR340 bit compared to standard air-bearing bits.
RR340 offers endurance and superior bit life in a range of drilling applications. The premium single-sealed roller bearing bit is designed for challenging ground conditions in wet and abrasive formations of medium or hard rock.
This rotary bit features Optional PowerCarbide®, cone steel protection, tailored coring protection and shirt tail tip hard metal protection. These elements protect against bit life wear in hard and abrasive rock, increasing bearing life.
In field tests, RR340 gives +45% increased service life and +25% bearing hours. This means fewer bit changes, which increases safety and is better for the environment and drilling economy.
