gauge protection 295mm hard rock drill tricone bit

Hard Formation TCI Bits For hard sandstones, granites, dolomites, quartzite and pyrites These Tricone Bits are designed to withstand high loads and drill abrasive conditions where rock is broken under high compressive point loads, with little scraping and gouging. Therefore, the cutting elements tend to be small, exhibit shorter protrusion and are more densely packed, which prevents the high compressive loads from breaking the tooth before it breaks the rock. Shirttail protection along with carbide leg protection increases bit life for HDD applications. Full bottom hole coverage and non-uniform insert spacing results in smooth drilling at high penetration rates .

These bits essentially consist of 3 roller cones having steel teeth or tungsten carbide inserts.As the drill string is rotated the bit cones roll along the bottom of the bore hole in a circular motion.As they roll,new teeth come in contact with the bottom of the hole which helps to chip away the rock formation below and around the bit tooth.Typically air or drilling fluid is used to lift the crushed rock chips from the bottom of the hole up the annulus.
