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.
