Product Description

Tricone bit
some IADC code for reference:

**7
Soft Formation TCI Tricone Bits
The **7 tci bits are used to drill low compressive strength,very soft formations .TCI bits maximize the use of bothconical and chisel tungsten carbide inserts of large diameters and high projection.This cutting sstructure design,combined with maximum cone offset,results in high bit penetration rates .The deep intermesh of cutter rows prevents bit bailing in sticky formations.
 **7
Medium Formation TCI Tricone bits
The **7features aggressive chisel tungsten carbide inserts on the heel rows and inner rows.This desing 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.
 **7
Hard Formation TCI Tricone Bits
The **7bits can be used to drill hard and abrasive formations .Wearresistant tungsten carbide inserts are used in the outer rows to prevent loss of bit gauge.Maximum numbers of bemisphericalshaped inserts are used in all rows to provide cutter durability and long life.
 **7
Medium-Hard Formation TCI Tricone Bits
The **7features robust chisel tungsten carbide inserts on the heel row and conical on the inner rows.This design provides a fast drilling rate and added sutti8ng structure durability in medium to medium hard formations .The HSN rubber o-ring [rovodes adequate sea;omg fpr bearomg dirability.

Steel tooth bits series
 ******7
Soft Formation Tooth Bits
The ******7 bits are used to drill low compressive strength,soft formations .Long projection tooth lengths are used on high offset cones to provide thegreatest penetration rates possible.Wear-resistant hard facing is used to control tooth wear.Onthe softest bit ty0pes this hard facing completely covers the bit teeth.
 **7
Medium-Hard Formation Tooth Bits
The **7bits are used to drill high-compressive strength,medium hard formations .Short projection teeth with reduced crest length are used in this series of bit designs .Durable hard facing is applied to reduce tooth wear
