Formations

Hard formation with high compressive strength ,such as hard shale,sandstone,dolomite, hard gypsum,chert,granite,etc.

4 5/8" TCI tricone bit is widely used in water well drilling, exploration, HDD pilot hole, foundation piling, it has a central jet hole design, so it is also workable for reverse circulation drilling.

The bearing is sealed, the working life is much longer than open bearing roller bits. Conical shape tungsten carbide insert has higher penetrating rate than spherical shape inserts in drilling hard rocks.
