Formations: long intervals of very soft poorly compacted shales ,sandstone, clays, salts and soft li mestones. Size and IADC available: 3 3/4" to 26" IADC 415,435,445,417,437,517,537,617,637,743
Cutting Structure of this type sealed and non-sealed tci tricone bits :
The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit.
Gauge Structure of this type tci tricone rock bits :
Multiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.
Bearing Structure of this type tci tricone rock bits :
High precision roller bearing with two thrust faces. Ball lock the cone.Thrust faces hardface with wear resistant alloy. Abrasion resistance and seizure resistance of the bearing are improved
