Open Bearing Steel Tooth Tricone Bit Brochure

The TR1 operates best in hard, abrasive formations such as hard sandy limestone interspersed with cherty streaks, broken shale, dolomite, granite, and abrasive sand. This bit is especially constructed to withstand the stresses imposed in drilling hard formations under heavy weights. The gage teeth are “T” shaped and hardfaced with tungsten carbide. There are no interruptions on the heel row teeth and the inner row teeth are short and closely spaced for maximum strength.
