Hole Opening

General Purpose Roller Cone

Our tungsten carbide insert (TCI) and milled tooth bits are designed for high durability, increased ROP and optimum drilling performance—each manufactured with different bearing designs to suit every drilling application.

Sealed bearing bits employ an improved bearing seal arrangement and lubrication and grease reservoir system to increase drilling hours—reducing the occurrence of early seal failure. Our open bearing bits effectively withstand higher pull-down loads, impact loads and rotation speeds, while an optimized cutting structure design and balanced load distribution reduces friction and eliminates unbalanced wear in the bearings.
