Flat End Taper Rounded edge
845KR‑314
(Ø1.6 mm x 4 mm)
This Ø1.6 mm bur features a flat end taper with a gentle rounded edge, ideal for cavity and fissure preparations as well as crown work. The 4 mm working length offers precise control when shaping shoulders and chamfers without cutting too aggressively. Its rounded tip reduces stress on internal line angles, making it perfect for prepping delicate tooth structures. Choose this when you need a smooth finish and conservative reduction.

(Ø1.8 mm x 4 mm)
A slightly larger Ø1.8 mm head increases efficiency while maintaining the same 4 mm length. Its flat end delivers crisp shoulder margins while the rounded edge protects adjacent tissue. Use this for crown preparations requiring a wider finish line or when removing old restorative material with confidence.

(Ø2.1 mm x 4 mm)
With a Ø2.1 mm diameter, this bur offers robust cutting power for bulk reduction during crown or veneer preparations. The rounded edge preserves internal anatomy and minimizes the risk of notching. A 4 mm length still provides excellent tactile feedback and control for uniform shoulder formation.
