1.TCI bitsseries:

• 1.Soft formation TCI triconebits:

         The softformation TCI tricone bits are used to drill low compressivestrength, very soft formations. This bit    maximized to use of both conical and chisel tungsten carbideinserts of large diameters and high projection. This cuttingstructure design, combined with maximum cone offset, results inhigh bit penetration rates. The deep intermesh of cutter rowsprevents bit bailing in sticky formations.

• 2.Medium formation TCI triconebits:

      The medium formationTCI tricone bits features aggressive chisel tungsten carbideinserts on the heel rows and inner rows. This design provides afast drilling rate and added cutting structure durability in mediumto medium hard for mations. The HSN rubber O-ring provides adequatesealing for bearing durability.

• 3.Hard formation TCI triconebits:

      The hard formationTCI tricone bits can be used to drill hard and abrasive formations.Wear resistance tungsten carbide inserts are used in the outer rowsto prevent loss of bit gauge. Maximum numbers of hemisphericalshaped inserts are used in all rows to provide cutter durabilityand long life.

• 4.Medium hard formation TCI triconebits:

     The medium hard formation TCItricone bits features robust chisel tungsten carbide inserts on theheel row and conical on the inner rows. This design provides a fastdrilling rate and added cutting structure durability in medium tomedium hard formations. The HSN rubber O-ring provides adequatesealing for bearing  durability 

2.Steel teeth bitsseries:

• 1.Soft formation teethbits:

The soft formations tooth bits are used to drill lowcompressive strength, soft formations. Long projection toothlengths are used on high offset cones to provide the greatestpenetrations rates possible. Wear resistance hard facing is used tocontrol tooth wear. On the softest bit types this hard facingcompletely covers the bit teeth.

• 2.Medium hard formations toothbits:

The medium hard formation tooth bits are used to drillhigh compressive strength, medium hard formations. Shoot projectionteeth with reduced crest length are used in this series of bitdesigns. Durable hard facing is applied to reduce toothwear.
