Achieving high rates of penetration through hard formations is a challenge, especially when drilling with high pressure air systems. Extreme drilling conditions cause stress on the cutting structure of the bit and lead to unbalanced wear on the bearings – reducing the life of the bit.


Challenges associated with mining and blast hole drilling:

  • Challenging lithology
  • High RPM
  • Heavy Weight on Bit
  • Low ROP


The Rubicon range of drill and blast air cooled bearing roller cone bits are designed to provide outstanding drilling speeds, yet be durable enough to keep drilling, longer. Specially formulated carbide grades, coupled with precision bearings in a range of sizes and types give you the security and peace of mind to keep drilling. If your application requires something different from the normal, then speak to us about custom designs, made for you and your challenges.
