TCI Tricone Drill Bits

Engineered for Extreme Durability

When drilling time is money, you can't afford premature failure. ValcoBlue's TCI Tricone Bits are built in the USA to withstand the most abrasive environments on earth. We use premium microwave-sintered tungsten carbide inserts and advanced bearing seal technology to deliver superior footage per run. Stop tripping for bit changes—keep turning to the right with confidence.
