High extension balling resistant cutting structure with forged teeth and self-sharpening tooth hardmetal for high penetration rates and long life in soft abrasive formations.

Traditional ball and roller bearing, utilizing thrust buttons for axial bearing loads, gives reliable performance under a variety of rotary speeds and loads.

The tooth surfaces are fortified with premium, high-density tungsten carbide hardfacing applied by oxy-acetylene welding for superior wear resistance.

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.)

"(349.2 mm) and smaller are manufactured with Varel's exclusive forged tooth process. This innovative method provides stronger, more impact-resistant teeth when compared with milling because the metal flow lines from the forging process follow the tooth contours instead of being cut by machining
