• Increases bit life in abrasive drilling environments
  • Provides exceptional ROP with custom cutting structure

  • Improves reliability with air bearing package



Our Vanguard™ air performance tricone drill bit combines extra-hard tungsten-carbide alloys with a customized insert layout to maximize penetration rates and downhole rock destruction in air-drilling applications.


Optimize performance

The bit’s uniformly applied tungsten-carbide hardfacing protects the body from damaging rock formations and debris, enhancing wear resistance while extending the life of bearing and seals. Further optimizing performance, the bit features a unique seal and bearing package engineered to improve bit life and reliability.


Maximize field performance across multiple wells

Tricone bit performance can be additionally enhanced through the Drilling Application Review Team (DART™). The DART process, which combines advanced technology, data, and designs, provides individualized solutions to maximize field performance across multiple wells while reducing risk.

The results are a true collaboration, drawing on unique resources, including a comprehensive database that taps our rich history of continual drilling improvements. The process also includes a state-of-the-art drilling laboratory and a full-scale research rig and downhole simulator. This combination of unique resources in a fully collaborative environment permits us to create tricone drill bits and systems that optimize performance, minimize drilling and completion costs while reducing nonproductive time.
