The Coltene Alpen Diamond Bur #859-014EF is an extra fine grit friction grip (FG) rotary instrument designed for delicate margin refinement, subtle contour correction, and final surface smoothing on enamel, composite, and ceramic restorations. Its slim needle/flame profile with a 1.4 mm head diameter and 10 mm working length provides precise access to embrasures, grooves, and curved anatomy while minimizing unnecessary material removal. The multi-layer diamond coating is engineered for uniform grit distribution, reduced vibration, and predictable wear, supporting consistent finishing results across repeated clinical use.
