IADC537 Sliding Bearing Insert Oil Well Drill Tci Tricone Bit
Versatility and Performance
Tricone drill bits has been in continuous use in the oil & gas industry, and is still being improved!
We have a wide selection of tricone bits - there’s a bit for every application.
Our product line can be configured to use tungsten car bide insert (TCI) bits and steel tooth bits for the toughest drilling applications.
