The Cup Bur is an essential finishing tool for any jewelry bench. Its concave cutting head rounds and smooths the ends of wire, prongs, and rivets cleanly and consistently, eliminating sharp edges and leaving a polished, professional result. Ideal for prong finishing, wire wrapping, and general jewelry fabrication where clean wire ends are required.
Manufactured by Busch. Standard 3/32" shank fits all common flex shaft handpieces, pendant drills, and micromotor systems.
