The Ultra X3 275 single roller cone bit is used for specialty drilling applications. Designed to deliver versatility in cobble and broken formations, the cone rotation helps smooth out the entire drill string, minimizing torque spikes. The bit is used for extreme cobbles and soft to medium rock.


Equipped with a unique, non-torqued spline connection system, the Vermeer Ultra X3 275 drilling system offers compatibility with a wide range of pilot bit and pullback configurations. The smallest Ultra X3 option, it’s designed for quick tooling changes without breakout devices or special tools.
