Flat End Taper
845‑314
(Ø1.4 mm x 4 mm)
A Ø1.4 mm flat‑end taper is ideal for conservative crown preparation. The tapered sides cut with minimal pressure, while the flat tip creates a uniform shoulder or chamfer for full‑ceramic margins. Its 4 mm length gives excellent control during incisal and facial reduction, facilitating precise clearance without over‑preparation.

(Ø1.8 mm x 6 mm)
With a Ø1.8 mm head and 6 mm working length, this bur is designed for deeper occlusal reduction and broader shoulder formation. It excels in crown and bridge preparation, providing smooth, continuous margins. The extra length makes it easier to reduce axial walls evenly and achieve proper occlusal clearance.

846‑314
(Ø2.3 mm x 7 mm)
This Ø2.3 mm flat‑end taper offers a 7 mm head for robust crown reduction on posterior teeth. It’s ideal for creating wide, flat shoulders and ensuring adequate occlusal clearance. The tapered sides help maintain a consistent taper, enhancing retention while minimising stress concentrations.

846‑314
(Ø2.5 mm x 7 mm)
Slightly larger at Ø2.5 mm, this bur provides even more surface area for rapid reduction and broad shoulder formation. It’s particularly suited for crowns requiring substantial clearance or for adjusting bulkier restorative material. The 7 mm head maintains a smooth path of insertion and reduces chair‑time.

848‑314
(Ø1.4 mm x 10 mm)
This Ø1.4 mm bur features a long 10 mm cutting surface for extended axial reductions. It’s indispensable when preparing long‑walled crowns or veneers that require uniform taper from gingival to incisal. The flat end ensures a defined shoulder while the taper guides the preparation toward the desired convergence angle.

(Ø1.8 mm x 10 mm)
This Ø1.8 mm, 10 mm long bur is designed for efficient crown and bridge preparations where both depth and breadth are required. It shapes axial walls and occlusal surfaces uniformly, facilitating accurate impression taking and fit. The flat end delivers a crisp shoulder ideal for all‑ceramic margins.

(Ø2.3 mm x 10 mm)
The largest of the series (Ø2.3 mm × 10 mm) provides unmatched efficiency in heavy posterior crown reductions. Its long head reaches deep surfaces while the wide diameter rapidly removes tooth structure. Use it when preparing full‑coverage crowns that demand significant clearance and a broad, flat shoulder.
