Cylinder Round Edge 
(835-314)
(Ø1.4 mm x 4 mm)
This Ø1.4 mm flat‑ended cylinder provides parallel walls and a level floor during cavity or crown preparation. The straight sides act like a file, ideal for removing old restorations and smoothing axial walls. Its 4 mm working length gives excellent control for crown reductions and cavity refinements. The flat tip ensures a flat base, promoting predictable margins.

(846KR-314)
(Ø1.6 mm x 6 mm)   
A Ø1.6 mm cylinder with rounded edges, designed for cavity, fissure and crown preparations. The 6 mm length provides enough reach to smooth axial walls and refine boxes without creating sharp angles. Its shape works like a file, offering parallel sides and a gentle end radius for stress‑free internal transitions. This bur excels at conservative reduction and is versatile in restorative and crown work.

(Ø1.8 mm x 6 mm)
With a Ø1.8 mm head, this bur retains the same 6 mm length but offers greater cutting surface for faster material removal. The rounded edges reduce the likelihood of gouging while still delivering smooth, parallel walls. Choose it for more substantial cavity or crown preparations that require efficiency and finesse.
