Busch 411CT Conical Twin Cut Cup Concave Head Burrs are used by stone setters to trim back the claws on rings. They are conical shaped to allow a closer cut and feature two cutting sides to remove the excess metal, prolonging the life of the burr. They feature a Ø2.35mm shank to be used in pendant drills and micromotors. These tungsten vanadium steel burrs are made to ultra-high precision tolerances.
