7. Reasonable price and long working life.

the characteristics of the drill bits

1. It has rolling sealed bearing structure. The cylinder rolling element is placed within the groove

of roller cone, thus enlarging the journal size and ensuring a better performance of roller bit.

2. The secondary surface of thrust bearing of roller bit has been handled with antifriction and

hardening treatment so as to decrease the frictional force of bit for protecting its hardening

resistance.

3. The roller bit uses new type lubricating grease which can bear the high temperature of 250°C and boasts abrasion resistance.

4. The full rubber oil reservoir uses limitable differential pressure and can prevent drilling fluid

from entering lubricating system so as to provide qualified lubrication for bearing system.

TCI bits series are used in different formations

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 a

nd 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.
