Round End Taper
(850-314)

(Ø1.4 mm x 10mm)
This Ø1.4 mm round end taper bur, with a 10 mm length, excels in crown and bridge preparations. Its tapered sides create smooth internal angles and chamfer finish lines while the rounded tip prevents gouging. Use it to refine axial walls and finish margins on full‑coverage restorations.

(Ø1.6 mm x 10 mm)
With a Ø1.6 mm head, this bur increases cutting efficiency while preserving the same 10 mm reach. The rounded end ensures gentle transitions, making it suitable for larger chamfer margins and deeper crown preparations.

(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)

(Ø1.6 mm x 6 mm)
This Ø1.6 mm bur offers efficient removal while still fitting in confined spaces. Its short length gives excellent control and tactile feedback. Ideal for adjusting margins and refining chamfers.

(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.

(856-314)

(Ø1.6 mm x 9 mm)
This Ø1.6 mm bur extends to 9 mm, offering increased reach while maintaining control. It’s perfect for deeper crown margins or for finishing long veneers.

(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.
