Busch® Tungsten Vanadium Concave Cutter Bur Set, 3.5

These Busch® concave cutter (cup) burs are used to round prongs, wire ends and rivet heads, and to shape or smooth prong tips; the cutting flutes inside the cup aggressively remove material for fast shaping. This set includes 8 burs, sizes 3.5mm through 10mm. Made from cost-effective tungsten vanadium, these burs cut precisely and can be used at low speeds.
