Weld On Style Ring Bits

Carbide Studded "Weld-On" Style Ring Bits Designed to aid in surface casing advancement, as part of new exploration “pad” development & prior to production drilling initiated at a hydraulic fracturing (fracking) site.

These bits are typically used under “dual” or conventional rotary drills & ultimately remain in the ground as part of the surface casing installation process.

Our Bits are heat-treated & utilize either Conical (Ballistic Carbide) style or Button style bits that are “induction braised” instead of simply pushed into each ring bit body.

This “induction” installation process assures that each bit stays put during the drilling process, so that the entire Ring Bit does its job with each & every casing installation.

Simply match your surface casing diameter, select a standard duty or heavy duty application and then either Conical (Ballistic Carbide) style or Button style bits when ordering,
