very hard formation. Our company firstly pay more attention tothe quality of the bits, all the bits have gain API
Certification, we have enjoyed great popularity in the world! We would like to establish business relations with you
and your company !
2. Structure Features of tricone rock roller bits
The Advantages of using a tricone bits over other drill bits
· There is a tricone suitable for any rock formation
· Tricone bits are versatile and can handle changing formations
· Tricones are reasonably priced with long life and good rate of drilling
Depending on your application we can provide you with new, re-run or premium oil field quality tricone bits. The difference between a premium oil field tricone bit and non-premium oil well quality tricone is that the roller cones have high end sealed bearings; extremely high quality tungsten carbide and offer
diamond gauge protection throughout the drill bit as well as skirt tail hard facing and optimized hydraulics. These roller cone drill bits are
designed to go to extreme depths in extreme conditions and in situations where they cannot fail.
When Ordering a bit the IADC bit classification system is a very useful tool and allows us to specify a bit that out preform your expectations.
Our TCI tricones bits Range in size from 3.875” (88.9mm) to 28” (711.2mm)
Our Mill tooth tri cone drill bits range in size from 5” (127mm to 32” (812.8mm)
IADC tricone roller cone classification system
· 4 character code, first 3 characters are numbers, the last is a letter
· 1st number is the series. 1 to 3 represent a milled tooth tri cones, 4 – 8 represent TCI tri cones. The higher the series number the harder more abrasive the rock formation is.
· 2nd number is the relative degree of hardness within a series. The number ranges from 1 – 4, the higher the number the harder the formation
· 3rd number represents bearing design and gauge protection.
1. Open bearing
2. Roller bearing air cooled
3. Open bearing gauge protected
4. Sealed roller bearing
5. Sealed roller bearing gauge protected
6. Sealed friction bearing
7. Sealed friction bearing gauge protected
· 4th character is a letter and describes optional features. There are 16 alphabetic character’s each representing the tricones most significant feature.
Mill tooth tricone drill bits
Mill tooth tricone drill bits have very high drilling rates in soft formations. Western Drilling Tools can hard face the milled teeth so that they sharpen themselves while drilling. Milled tooth tricone bits are designed for very soft to medium hardness formations.
Sealed Bearing mill tooth tri cone bit with or without gauge protection
These are the best preforming and longest lasting style of tri cone on the market. Guage protection increases the life of the drill bit.
Open Bearing mill tooth tri cone roller cone bit can come with or without gauge protection
These are less expensive then sealed bearing but they typically do not last as long.

5.Tricone bits can used for soft to hard formation:
Soft formation TCI tricone 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.
