Low Compressive Strength 6 3/4" IADC635 Tricone Drill Bit TCI Roller Rock Bits
TCI Tricone bits offer a variety of carbide inserts such as spherically shaped inserts for very hard rock or conically shaped inserts for softer rock. The number of rows of inserts is directly related to the type of application and the size of hole to be drilled. There are also open and sealed bearings available as well as three types of shirttail protection to choose from. Finally, Focus rotary bits can use both fluid and air circulation.
