Alpen Multi-Use Multilayer Diamond Instruments are Swiss-made friction grip (FG) rotary burs featuring a two-layer natural diamond coating: an initial layer bonded to the steel shank for anti-vibration stability and a second layer providing full diamond coverage, so fresh sharp edges are exposed as outer layers wear. This extra fine (yellow ring) #858 needle/flame profile has a 1.4 mm head diameter and 8 mm head length, making it well suited for delicate margin refinement, contour smoothing, and final surface finishing on enamel, composite, and ceramic before polishing. Supplied in user-friendly, securely sealed peel-open blister packs of 5.
