NeoBurrĀ® FG 8SL Surgical Length Round Carbide Bur by Microcopy (USA). Engineered from a single piece of solid tungsten carbide with an extended surgical length friction grip shank (SL) and a wide 2.3 mm round cutting head. Specifically designed for deep oral surgery procedures requiring maximum clearance, rapid bulk bone removal, unroofing large pulp chambers, sectioning multi-rooted teeth, and excavating deep extensive caries where standard shank length restricts visibility or reach.
