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 Oring provides adequate 

sealing for bearing durability.
