TRICONE ROCK BITS

Penetration and wear are the two key elements of consistent drilling. We deliver solutions for the toughest mining and energy sectors.

Roller Cone Technology

Also known as roller cone bits or TriCone bits, these feature three moving heads designed to crush and grind rock. Our engineering focus ensures the optimal bearing type for specific drilling environments.

TWO MAIN CLASSIFICATIONS:

Superior Bearing Systems

High endurance bearing designs to accommodate various drilling applications and fluids.

1. Standard Open Bearing

Free-spinning cones with front row ball bearings and back row roller bearings. Ideal for standard mud drilling.

2. Air Cooling Bearing

Features direct air injection to cool the bearings during high-speed air drilling operations. (Not for mud).

3. Sealed Roller Bearing

Utilizes O-Ring seals and grease reservoirs for continuous cooling and protection against debris ingress.

4. Journal Bearing System

Strictly oil/grease cooled for maximum performance. Includes nose bearings and highly durable seals.

Formation Categories

  • Soft Formation: Used in unconsolidated sands, clays, soft limestone, and red beds.
  • Medium Formation: Designed for calcites, dolomites, limestones, and hard shale.
  • Hard Formation: Built for cherty limestone, mudstones, and highly abrasive formations.

Fluid Circulation

Active fluid circulation (water, oil, air, or foam) is critical for:

  • Cleaning: Instant removal of cuttings to prevent recutting.
  • Cooling: Preventing overheating of cutters and bearings.
  • Stability: Pressure regulation for borehole wall integrity.
