TCI Tricone Bits

TCI stands for Tungsten Carbide Insert. These tri cones are designed for soft to very hard formations depending on the style and quantity of the carbides on the drill bit.

Sealed Bearing TCI Tricone bit with or without gauge

These are the best preforming and longest lasting style of tri cone on the market. Sealed bearings will out perform open bearings. Gauge protection greatly increases the life of the drill bit.

Open Bearing TCI Tricone bit with or without gauge protection

Open bearing tricones can be gauge protected or not. These tri cone bits have exceptional value, good performance and low cost. Gauge protection greatly increase the life of the drill bit.

IADC Code Reference

First Digit:

Tungsten Carbide Inserts Assign numbers 4-8. The higher the series number the harder more abrasive the rock formation.

Second Digit:

Relative degree of hardness within the series. Higher numbers indicate harder formations. Numbers range from 1-4 further assist in identifying the formation with 4 being the Hardest & 1 being the Softest.

Numbers 1-7 indicate the primary Seal/Bearing Design, Seal protection & Special Gauge Wear.

  1. Open Bearing
  2. Open Bearing [Air Cooled]
  3. Open Bearing w/ Gauge Protection
  4. Roller Sealed Bearing
  5. Roller Sealed Bearing w/ Gauge Protection
  6. Sealed Friction Bearing
  7. Sealed Friction Bearing w/ Gauge Protection
