Normal IADC:
437 Soft Formation TCI Tricone Bits:
The 437 TCI bits are used to drill low compressive strength, very soft formations. TCI bits maximize the 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.
517Medium Formation TCI Tricone Bits:
The 517 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 formation. The HSN rubber O-ring provides adequate sealing for bearing durability.
637Hard Formation TCI Tricone Bits:
The 637 bits can be used to drill hard and abrasive formation. Wear-resistant 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.
617Medium-Hard Formation TCI Tricone Bits:
The 617 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.

Different Tooth Shapes And Application:
Dome / Round button 
Used as gauge buttons of DTH bits, suitable for very abrasive and very hard rock formation.
Parabolic / Semi-ballistic
 Used as gauge buttons and front buttons of DTH Bits, suitable for medium abrasive and hard rock formations.
Ballistic button
Used front buttons of DTH bits, suitable for medium abrasive and medium hard formations. Also be used as gauge buttons for soft rock.
