Suitable formation of the TCI tricone bit

Medium to Hard Formation TCI Bits
For medium-hard shales, limestones, sandstones and dolomites

These Tri-Cone ™ Bits have moderately sharp conical or chisel inserts with a shorter extension. An increased insert count helps reduce breakage when drilling in harder formations. Full bottom hole coverage and non-uniform insert spacing results in smooth drilling at high penetration rates.

The TCI tricone bit features:Short, closely spaced teeth to withstand heavier impact loads

From C3 to C5 type Carbide Tri-Cones

Sizes range from 4 3/4"to 26"
