Oil / Water Well Drilling Cone Shaped Drill Bit , Roller Cone Drill Bit Forging Type

Soft formation TCI bits:

The soft formation TCI 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 diameter 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 bits

The medium formation TCI bits features aggressive chisel tungsten carbide inserts the heel rows and 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.

Hard formation TCI bits:
The hard formation TCI 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 bits:

The medium hard formation TCI 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.
