This Busch® (cup) bur is used to round prongs, wire ends and rivet heads, and to shape or smooth prong tips. Specially designed to enable the rapid removal of metal, the Twincut feature allows debris to be quickly shed through the two channels in the bur head. Made from cost-effective tungsten vanadium, this bur cuts precisely and can be used at low speeds.
