6 3/4" IADC 632 blasthole bit tci tricone bit oil drilling
machine/hard rock drilling bits
The soft formation TCI tricone bits are used to drill low compressive strength, very soft formations.
This bit maximized to use of both conical and chisel tungsten
carbide 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 bailing in sticky formations.
Medium formation TCI tricone bits:
The medium formation TCI tricone bits features aggressive chisel
tungsten carbide inserts on the heel rows and inner rows. This
design provides a fast drilling rate and added cutting structure
durability in medium to medium hard for mations. The HSN rubber
O-ring provides adequate sealing for bearing durability.
Hard formation TCI tricone bits:
The hard formation TCI tricone bits can be used to drill hard and
abrasive formations. Wear resistance
tungsten carbide 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.
Medium hard formation TCI tricone bits:
The medium hard formation TCI tricone bits features robust chisel tungsten carbide inserts on the heel row
and conical on the inner rows. This design 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.
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.
