12-1/4" Tricone Rock bit,6⅝ API Reg. IADC code 447,used in
MEDIUM-HARD Rock
Product Description
(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.

Feature
IADC437 | The 437 tci bits are used to drill low compressive strength,very
soft formations .TCI bits maximize the use of bothconical and
chisel tungsten carbide inserts of large diameters and high
projection.This cutting sstructure design,combined with maximum
cone offset,results in high bit penetration rates .The deep
intermesh of cutter rows prevents bit bailing in sticky formations. |
IADC517 | The 517features aggressive chisel tungsten carbide inserts on the
heel rows and inner rows.This desing provides a fast drilling rate
and added cutting structure durability in medium-to –medium hard
formations .The HSN rubber o-ring provides adequate sealing for
bearing durability. |
IADC637 | The 637bits can be used to drill hard and abrasive formations
.Wearresistant tungsten carbide inserts are used in the outer rows
to prevent loss of bit gauge.Maximum numbers of bemisphericalshaped
inserts are used in all rows to provide cutter durability and long
life. |
IADC617 | The 617features robust chisel tungsten carbide inserts on the heel
row and conical on the inner rows.This design provides a fast
drilling rate and added sutti8ng structure durability in medium to
medium hard formations .The HSN rubber o-ring [rovodes adequate
