Cutting Structure

Bearing Package
| Traditional ball and roller bearing, utilizing thrust buttons for axial bearing loads, gives reliable performance under a variety of rotary speeds and loads.
|
Premium Hardfacing
| The tooth surfaces are fortified with premium, high-density tungsten carbide hardfacing applied by oxy-acetylene welding for superior wear resistance.
|
Center Jet Nozzle
(feature)
| A fourth interchangeable jet is installed in the center of the bit to reduce bit balling or provide extra flow capacity. (Available only in 8 3⁄8" bits and larger.)
