Steel tooth bits series:

Soft formation tooth bits:

The soft formations tooth bits are used to drill low compressive strength,soft formations. Long projection tooth lengths are used on high offset cones toprovide the greatest penetrations rates possible. Wear resistance hard facing isused to control tooth wear. On the softest bit types this hard facing completelycovers the bit teeth.

TCI bits series:

Soft formation TCI tricone bits:

The soft formation TCI tricone bits are used to drill low compressivestrength, very soft formations. This bit maximized to use of both conical andchisel tungsten carbide inserts of large diameters and high projection. Thiscutting structure design, combined with maximum cone offset, results in high bitpenetration rates. The deep intermesh of cutter rows prevents bit bailing insticky formations.

Medium formation TCI tricone bits:

The medium formation TCI tricone bits features aggressive chisel tungstencarbide inserts on the heel rows and inner rows. This design provides a fastdrilling rate and added cutting structure durability in medium to medium hardfor mations. The HSN rubber O-ring provides adequate sealing for bearingdurability.

Hard formation TCI tricone bits:

The hard formation TCI tricone bits can be used to drill hard and abrasiveformations. Wear resistance tungsten carbide inserts are used in the outer rowsto prevent loss of bit gauge. Maximum numbers of hemispherical shaped insertsare 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 tungstencarbide inserts on the heel row and conical on the inner rows. This designprovides a fast drilling rate and added cutting structure durability in mediumto medium hard formations. The HSN rubber O-ring provides adequate sealing forbearing durability.

Medium hard formations tooth bits:

The medium hard formation tooth bits are used to drill high compressivestrength, medium hard formations. Shoot projection teeth with reduced crestlength are used in this series of bit designs. Durable hard facing is applied toreduce tooth wear.
