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.
Features of TCI Bits
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”
