1>This model of TCI tricone bits is for drilling depth shallower than1000 meters, water well application or trenchless pilot hole which distance shorter than 200 meters. 2>The central jet hole could be used in reverse circulation drilling application. 3>IADC637G is conical shape tungsten carbide inserts with journal sealed bearing and gauge protection on heel of cones. The bearing is sealed by elastomer O-ring, bearing lubricated by grease compensation system. 4>For deep well drilling, we advise metal-face sealed bearing tricone bits or higher grade elastomer sealed bearing tricone bits, please contact with us for more information.
