The Coltene Whaledent - Alpen Diamond Instruments Et9-314-014-9.00-Ef, conveniently provided in a package of 5 burs, are specialized, Swiss-made diamond instruments particularly for the meticulous final finishing and pre-polishing of composite restorations, porcelain, and other esthetic materials. Featuring the 1.4 mm head diameter, 9.0 mm head length, and the distinctive ET9 shape (also cataloged as 135), these instruments are part of the Esthetic Finishing line, designed for contouring and refinement with minimal trauma to surrounding tissues.

The Extra Fine (EF) grit is color-coded with a yellow ring on the shank, indicating a low-abrasive surface roughness of approximately 25??m, which is critical for creating a very smooth surface texture before the final polishing stage. This careful surface refinement minimizes plaque accumulation and enhances the longevity and brilliance of restorations. The unique multi-layer diamond bonding process secures complete and uniform natural diamond coverage, especially at the critical tip, ensuring exceptional cutting longevity, sustained efficiency, and superior dimensional control throughout the finishing procedure.

The FG (Friction Grip) shank is engineered for a secure fit in all standard high-speed handpieces, guaranteeing stability and precision during the fine detailing of margins and surface anatomy. If you're searching for a highly effective and reliable tool for superior esthetic finishing and surface refinement on restorative materials, the best esthetic finishing diamond bur is a definitive choice for any dental professional.
