The Coltene Alpen X1 Extra Fine Diamond Bur with a pointed cone shape (#859, 1.4 mm diameter) offers exceptional finishing performance for restorative dentistry, crown preparation refinement, margin detailing, and high‑precision enamel/ceramic contouring. Designed as a sterile, single‑use diamond rotary instrument with a friction grip (FG) shank for high‑speed handpieces, this bur delivers consistent quality and reduced cross‑contamination risk.

Each bur in this 25‑pack is individually gamma‑sterilized and coated with natural diamond particles for uniform grit distribution and superior cutting control. The extra fine grit (yellow coded) smoothly polishes enamel and restorative surfaces with minimal micro‑scratches, an ideal choice for final finishing and delicate adjustments during operative and prosthodontic workflows.
