Description of drill bit
 
(1) Cutting Structure of this series tricone rock bit :
The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit.
 
(2) Gauge Structure of this series tricone rock bit :
Multiple gauge protection with gauge trimmers on 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.
 
(3)Bearing Structure of this series tricone rock bit :
High precision bearing with two thrust faces. Balls lock the cone.Hardface heard bearing surface. Cone bearing inlaid with friction-reducing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved and suitable for high rotary speed.
 
(4)Seal and Lubrication of this series tricone rock bit :
The advanced metal seal package consists of two metal seats and two elastic energizers. Compressed energizers ensure good contact being kept on two sealing surfaces of metal rings by elastic force, and achieve the bearing seal. In the drilling, metal seal are relatively dynamic, and the energizers are static. This will improve the reliability and durability of bearing seal. The pressure compensator system and advanced grease can greatly increase the lubricating reliability.

IADC Code Classifications

STEEL MILLING TOOTH BITS

IADC 1 SERIES DRILL BITS
These bits are used to drill low-compressive strength, soft formations. Long projection tooth lengths are used on high offset cones to provide the greatest penetration rates possible. Wear-resistant hardfacing is used to control tooth wear. On the softest bit types this hardfacing completely covers the bit teeth.

IADC 2 SERIES DRILL BITS
These bits are used to drill high-compressive strength, medium hard formations. Short projection teeth with reduced crest length are used in this series of bit designs. Durable hardfacing is applied to reduce tooth wear.

IADC 3 SERIES DRILL BITS
These bits are used to drill hard and abrasive formations. Very short, closely spaced teeth with minimum amounts of hardfacing are used for breakage resistance. These bits must withstand high loads and drill abrasive formations with a crushing, cutting action.

TCI (TUNGSTEN CARBIDE INSERT) BITS

IADC 4 SERIES DRILL BITS
These bits are used to drill low compressive strength, very soft formations. The bits maximize the use of both conical and chisel inserts of large diameters and high projection. This cutting structure design, combined with maximum cone offset, results in high bit penetration rates. The deep intermesh of cutter rows prevents bit balling in sticky formations.

IADC 5 SERIES DRILL BITS
These bits are used to drill low compressive strength, soft to medium soft formations. Drill bit design features are used to enhance bit penetration rates. Some reduction in cone offset and insert projection is used to improve cutter durability. Insert numbers and pitch is controlled to prevent tracking.

IADC 6 SERIES DRILL BITS
These bits are used to drill high-compressive strength, medium hard formations. A small amount of cone offset and low insert projection is used to prevent cutting structure damage when hard streaks are encountered. Increased numbers of blunter, smaller diameter inserts are used to increase life in harder, more abrasive formations.

IADC 7 SERIES DRILL BITS
These bits are used to drill hard and abrasive formations. A more wear-resistant grade of tungsten carbide insert is used to prevent wear. Low cone offset with increased numbers of breakage resistant cutters add to the required bit durability.

IADC 8 SERIES DRILL BITS
These bits can be used to drill extremely hard and abrasive formations. Wear-resistant inserts are used in the outer rows to prevent loss of bit gauge. Maximum numbers of hemispherical-shaped inserts are used in all rows to provide cutter durability and long life.
