Steel Tooth Tricone Drill Bit for Soft Formation Drilling

Steel Tooth Tricone Drill Bit uses machined steel teeth on three rotating cones to provide efficient crushing, scraping and rolling action during rotary drilling.

Compared with TCI bits, the milled-tooth structure is particularly suitable for softer formations where longer and more aggressive teeth can achieve efficient penetration. Available in multiple IADC configurations, diameters, bearing structures and thread connections, with bit sizes matching our TCI tricone product range.

Aggressive cutting for soft formations

Six design advantages behind the Steel Tooth Tricone Drill Bit.

Used across water well, mining and construction drilling

Steel tooth tricone drill bits are suitable for water well drilling, mining drilling, geotechnical drilling and rotary drilling. Other applications include reverse circulation drilling, grouting and injection drilling, construction drilling, soft formation drilling and oil and gas drilling in suitable configurations.

Milled steel tooth cutting structure

The cutting structure of a Steel Tooth Tricone Bit is different from a TCI bit. Instead of pressed carbide inserts, the teeth are machined from the cone steel itself. By changing tooth shape, spacing and exposure, the bit can be adapted to different soft rock and interbedded formations.

Protect borehole gauge and extend bit life

Depending on the drilling application, different gauge and wear protection methods can be used to maintain borehole diameter, reduce outer-diameter wear and extend bit life.

Open, sealed and journal bearing options

Depending on bit size and application, different bearing configurations can be selected to match the drilling environment.

Which tricone bit should you choose?

Steel Tooth and TCI tricone bits are designed for different formations and drilling priorities. The correct choice depends on formation hardness, abrasiveness, penetration requirement and drilling economics.

Product parameters and available options

Bit sizes match our TCI tricone product range. Both inch and millimeter sizes are available on request.
