Alpen Diamond Bur, FG, Interproximal, Fine, Red, #392-021F, 2.1 mm Head, 10 mm Head Length, 5/Pk, 60031837

Alpen Multi-Use Multilayer Diamond Instruments are Swiss-made, friction grip (FG) rotary burs featuring a fine diamond grit and an interproximal (flame) shape for finishing, margin refinement, and surface smoothing on enamel, composite, and ceramic. The 2.1 mm head diameter and 10 mm head length provide extended reach for deeper preparations, while the two-layer diamond coating bonds to the steel shank to reduce vibration and exposes fresh sharp edges as outer layers wear. Each pack contains 5 burs, color-coded red for fine grit.
