This Busch® lens bur is similar to a knife-edge bur but features an arcing taper from the center out to a sharp knife-like edge around its circumference. The top and bottom surfaces feature cutting flutes ideal for grinding in close areas such as prong seats and create a wider-angled cut. The lens bur is useful for removing material from contoured surfaces. Made from cost-effective tungsten vanadium, this bur cuts precisely and can be used at low speeds.
