Power Factory 444.5mm IADC217 Caly Tooth Tricone Drilling Bit
JSBIT tricone bits factory offers all kinds of tricone drill bits.
Tricone bits are available in new and used tricone bits , steel
tooth and tungsten carbide insert, in sizes from 37/8" to 36", for
use in all formations, with any bearing: seal type / air type ,
tricone bits apply to oil gas geothermy mining water HDD and
foundation industry.
Main features:
1. Cutting Structure of this type sealed and non-sealed tci tricone
bits
Tungsten carbide insert tricone bit : tungsten carbide alloy steel
Steel tooth tricone bit : Enhancing the wear-resistance of cutting
tooth by welding new type of wear resistant material on the tooth
surface of steel tooth bit. Reinforcing the comprehensive
mechanical properties of cutting tooth by using high quality
tungsten carbide inserts of new formula and new techniques of
insert bit.
2. Gauge Structure of this type tci tricone rock bits:
Gauge Structure
The multiple heel position with gauge trimmer on the heel, tungsten
carbide and hardfacing on the shirttail, strengthened spear point
will enhance the gauge protection.
1)Rubber sealed Bearing Structure
High precision journal bearing with two thrust faces. Ball locked
cone. Hardfaced head bearing surface. Cone bearing inlaid with
friction reducing alloy and then silver-plated. Abrasion resistance
and seizure resistance of the bearing are improved.
Seal and Lubrication
The bearing seal is adapting the high quality HNBR O-ring. The best
seal compression and the radial seal structure can enhance the seal
performance. The compensation system and the high quality bit
grease can limit pressure differential, and greatly increase the
lubricating reliability.
2)Metal Sealed Bearing Bit
Bearing Structure
High precision journal bearing with two thrust faces. Ball locked
cone. Hardfaced head 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.
Seal and Lubrication
The advanced metal seal package is composed by two metal seals and
two elastic rubber energiners. The energizer and back-up ring will
support the pushing force to make the two metal faces tightly
contact. In the drilling, the metal seals are relevant moving, and
the energizers are static. This will increase the bearing seal
reliability and durability. The compensation system and the high
quality bit grease can limit pressure differential, and greatly
increase the lubricating reliability.
3) rubber seal bearing Bit
Air cooling roller bearing package.Balls lock the cone,which
reduces the probability of cone-dropping to minimum.

Re-Run Carbide Insert Tricone Drill Bits
Re-run carbide insert bits are used bits that have been re-worked,
cleaned, and often times painted. Re-runs offer significant cost
savings over new carbide insert bits. Roschen offers a variety of
re-run carbide bits in sizes ranging from 2 1/2" to 36". All
re-runs are premium quality and available for use in soft, medium,
and hard formations.
Contact a us for additional details about our complete line of
re-run carbide insert tricone drill bit product offerings.
Re-Tip Steel Tooth Tricone Drill Bits
Re-tip steel tooth tricone bits are gently used bits that usually
come from the oil fields. They are refurbished for use in
non-oilfield rotary applications, such as water wells, HDD, and
construction type drilling. These bits offer significant cost
savings over new bits. Hole Products offers a wide range of
premium, oil field quality re-tip steel tooth bits in sizes ranging
from 2 1/2" to 36". Re-tip bits are available for use in soft,
medium, and hard formations.
