Description

  • Three-cone rolling cutter structure for efficient rock crushing and fragmentation under high load and rotational speed
  • Tungsten carbide inserts providing high wear resistance and durability in soft to hard and abrasive formations
  • Enhanced penetration efficiency and reduced energy loss
  • Reinforced gauge and transition zones improving structural strength and maintaining hole diameter accuracy
  • Reduced risk of tooth breakage under demanding drilling conditions
  • Bearing system designed for high loads and rotational speeds with improved load distribution and reduced friction
  • Extended operational life through durable and protected bearing design
  • Increased shirttail thickness protecting critical areas from wear and erosion
  • Smoother rotation, balanced forces, and reduced vibration
  • Stable drilling performance with improved overall efficiency
  • Efficient cuttings evacuation enabled by optimized internal geometry and cone spacing
  • Low torque requirements due to reduced borehole wall friction and efficient cutting action
  • High weight-on-bit (WOB) capacity allowing operation under heavy loads without structural compromise

 

Total drilling cost

Bit performance study records help estimate operational costs to determine the most economical bit types to use for each operating condition. Rock drill bit performance are evaluated by tracking meters drilled and penetration rates for an individual bit.

Total drilling cost is the cost of the bit plus the cost of operating the drill. The speed at which the bit drills is included by dividing the cost of the drill/hour by the penetration rate of the bit:
