Completion Tricone Bits

Moab Bit & Tool carries a full line of new, used and reconditioned tricones. Shown below are a sample of the range of bits we carry. Tricone bits can be custom jetted or skirted to suit your needs.

NOTE: Contact us for IADC code info. We have many different sizes and styles available. We can add special features to suit specific applications, and offer a complete line of tricone bits.

custom drill bits

RMB TR51

Soft to Medium Soft Formations such as soft shales, sands, clays, soft limestone and other unconsolidated formations. This bit employs maxi- mum cone offset and long chisel inserts for effective gouging and scrap- ing formation removal. Ample hard facing is applied along with flat TCI inserts on the gage of the cone. These features provide maximum protection against abrasion and add additional bearing life. Suggested operating weights are from 1,000 to 3,000 pounds per square inch of bit diameter with corresponding speeds of 200 to 50 RPM.

RMB TR53

Medium Soft Formations. The TR53 design utilizes the same cone structure as the TR51 but with all conical shaped inserts for efficient drilling in medium soft formations such as shale, sandstone, and alluvial deposits. This design employs the same maximum offset as the TR51; however, the conical shaped inserts provide greater wear resistance in the harder formations for which the bit is designed to drill. Ample hardfacing is applied to the shirttail providing maximum protection against abrasion and insures the longest possible bearing life. The most effective weight range varies from 1,5000 to 5,000 pounds per inch of bit diameter, while rotary speeds of 175 to 50 RPM give best performance. Rotary speed should be decreased as weight is increased.

custom drill bits

RMB TR61

Medium Formations with harder streaks such as limestones, sands, dolomites, and medium to hard shales. This design features short to medium extension chisel inserts throughout and moderate cone offsets which provides for very high penetration rates while maintaining excellent durability in a wide variety of formations. Ample hardfacing is applied along with flat TCI insert protection on the gage of the cone. These features provide maximum protection for added bearing life. Suggested operating weights are 1,000 to 3,000 pounds per square inch of bit diameter with corresponding speeds of 180 to 40 RPM.

custom drill bits

RMB TR63

Medium Hard Formations such as hard, sandy limestone, shale, dolomite and limestone with cherty streaks. This design features conical shaped tungsten carbide inserts on the gage rows to inhibit gage wear and chisel shaped inserts on the inner rows to get maximum penetration. Gouging/ scraping action is provided by the cone offset. Ample hardfacing on the shirttail provides maximum protection against abrasion and insures the longest possible bearing life. Suggested operating weights are 1,500 to 6,000 pounds per inch of bit diameter with corresponding rotary speeds of 140 to 55 RPM. Near the bit stabilization is recommended for maximum bit life.

custom drill bits

RMB TR64

Medium Hard to Hard Formations. The TR64 is similar to the TR63 but with dome shaped TCI inserts on the gage rows and chisel shaped inserts on the inner rows for best performance in tight and well cemented medium hard to hard formations such as abrasive limestone, sandstone and dolomite where maximum gage wear resistance is required. Ample hardfacing is applied to the shirttail providing maximum protection against abrasion and insures the longest possible bearing life. Suggested operating weights are 1,500 to 6,000 pounds per inch of bit diameter, while rotary speeds of 140 to 55 RPM give best performance. Rotary speed should be decreased as the weight is increased. Near the bit stabilization is also recommended for maximum bit life.

custom drill bits

RMB TR74

Medium Hard to Hard Formations. The TR74 features a minimum offset cutting structure design and all dome shaped TCI inserts. It is designed to drill hard and abrasive formations such as quartzite, granite, cherty iron ores, and copper porphyry. This design features shirttail hardfacing for maximum resistance to bearing wear. The drilling weights should range from 1,500 to 8,000 pounds per inch of bit diameter. As drilling weights are increased the rotational speed, which ranges from 120 to 50 RPM, should be decreased. Near the bit stabilization is highly recommended for maximum bit life, and pull down drills should be equipped with shock absorbers.
