Our ring bits are used on the outer casing of overburden and casing drilling systems. They cut the outer section of the borehole and enable the casing to advance into the ground.

Depending on the drilling method and ground formation, different cutting-edge and tungsten carbide configurations are available.

Our ring bits offer:

-   Designs for rotary and rotary-percussive drilling
-   Various diameters, thread types and cutting-edge configurations
