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.


Solidkey is an API certified factory of tricone roller bit, please contact with us for more information.
