TCI Tricone Bits
Tungsten carbide insert bits for medium to very hard, abrasive rock.
Overview
Tungsten carbide insert (TCI) tricone bits crush hard rock with carbide inserts pressed into three rotating cones. They are the workhorse for hard, abrasive and fractured formations where fixed cutters would chip.
Insert shape, extension and spacing are matched to formation hardness, while sealed bearings and gauge protection keep the bit in gauge to the end of the run.
Key Features
- Carbide insert shapes from chisel to conical for different rock strengths
- Sealed roller or journal bearing designs
- Gauge and heel row protection for hole quality
- Jet nozzles for cleaning and cooling
Applications
- Hard limestone, dolomite and quartzitic sandstone
- Interbedded and fractured sections
- Geothermal and hard-rock exploration wells
