A revolutionary patented cup bur design. The "Champion Cup" has no inner baldes, instead it features two 'slotted' openings opposing each other. Outstanding "smooth" surface prong eliminates additional polishing procedure. No "clogging" on softer metals and particularily good for platinum. Guaranteed to outlast conventional cup burs over two times. The FCC Champion Cup is the ultimate cup bur for reaching tight places and rounding prongs that are very close together, because it has an extra thin wall - a setters favorite.
