TCI

Tricone bit

This kind of TCI bits are used to drill low compressive strength ,medium  formation.TCI bits maximize the use of both conical and chisel tungsten carbide inserts of large diameters and high projection.This cutting structure design ,combined with maximum cone offset ,results in high bit penetration rates .The deep intermesh of cutter rows prevents bit bailing in sticky formations .

suitable formation:hard shale,softlimestone, sandstone, dolomite, ect.
