Round End Taper
(850-314)

(Ø1.8 mm x 10 mm)
A Ø1.8 mm diameter provides more surface area for rapid reduction. Its 10 mm length maintains a consistent taper, helping you achieve adequate clearance for porcelain‑fused‑to‑metal or zirconia crowns.

(856-314)

(Ø1.6 mm x 8 mm)    
With a Ø1.6 mm head, this bur provides efficient cutting over an 8 mm length. It’s ideal for routine crown and bridge preparations, creating a gentle chamfer and smooth axial walls.

(Ø1.8 mm x 8 mm)
The largest of the 856 series (Ø1.8 mm × 8 mm) excels at rapid reduction with a rounded end that preserves internal structures. Use it when you need efficiency and a smooth chamfer finish on wide preparations.
