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.

(Ø2.3 mm x 10 mm)
This Ø2.3 mm bur offers significant cutting power for robust crown preparations. It delivers broad chamfer margins with a smooth, rounded internal angle. Ideal when bulk reduction and smooth finish are both required.

(855-314)

(Ø1.2 mm x  6 mm)
A slender Ø1.2 mm taper with a 6 mm length is perfect for conservative chamfer margins and finishing narrow interproximal areas. The round end ensures safe widening of canal walls without risk of gouging. Choose this when working on small teeth or tight spaces.

(Ø1.4 mm x  6 mm)
Slightly larger at Ø1.4 mm, this bur maintains a 6 mm working length for quick crown or bridge preparations with minimal risk of overcutting.

(Ø2.5 mm x 7 mm)
The largest of the 855 series (Ø2.5 mm × 7 mm) is designed for substantial reduction where a broad chamfer is needed. The round end helps maintain internal integrity while the taper ensures a smooth path of insertion.
