Long Round End Taper
850‑314

(Ø1.4 mm x 11.5mm)
This bur combines a Ø1.4 mm head with an extended 11.5 mm cutting surface, providing deep access for long‑wall crown preparations. The round end prevents gouging, while the taper creates a gentle chamfer for precise crown and bridge margins. Its extra length lets you maintain a consistent taper from gingival to occlusal without repositioning instruments.

(Ø1.6 mm x 11.5 mm)
At Ø1.6 mm, this long taper bur offers increased cutting efficiency while retaining the same smooth, round‑ended profile. It excels in preparing full crowns and veneers where both depth and breadth of reduction are required. Use it to shape axial walls and occlusal surfaces uniformly over extended areas.

(Ø1.8 mm x 11.5 mm)
With a Ø1.8 mm diameter, this bur is designed for robust reductions on posterior teeth. The 11.5 mm length ensures deep access and consistent taper, while the round tip produces smooth internal angles that minimise stress on ceramic restorations. Ideal for preparations requiring significant clearance and a broad chamfer.

856‑314

(Ø1.6 mm x 10 mm)
This Ø1.6 mm variant provides more cutting surface for efficient reduction, retaining the same 10 mm reach. It’s ideal for preparing larger teeth or refining full‑coverage crown margins with a smooth, stress‑reducing chamfer.

(Ø2.1 mm x 10 mm)
The largest of the series (Ø2.1 mm × 10 mm) offers substantial cutting power for heavy reductions. Its taper ensures a uniform path of insertion, and the rounded tip prevents sharp internal corners that can weaken restorations. Choose it when you need to prepare broad, deep shoulders on molars or adjust bulk restorative material quickly.
