Frank Dental D.845KR.021 Inlay Preparation Bur
Tapered Shoulder Round Edge Diamond Bur – 2.1mm Diameter (1.4mm Tip)
The Frank Dental D.845KR.021 tapered shoulder round edge diamond bur is designed for precise inlay, onlay and indirect restorative preparations. Featuring a 2.1mm maximum diameter with a 1.4mm narrow tip diameter, this diamond bur provides the ideal balance between efficient tooth reduction and controlled cavity refinement for modern adhesive and ceramic restorative dentistry.
The tapered shoulder with round edge geometry allows dentists to create smooth cavity walls and rounded internal line angles, helping reduce stress concentration within ceramic restorations such as lithium disilicate and CAD/CAM inlays. The preparation design also supports improved restoration seating, marginal adaptation and long-term clinical durability.
The D.845KR.021 is ideal for clinicians searching for a:

The 2.1mm working diameter enables efficient occlusal reduction and cavity shaping, while the 1.4mm tip diameter provides excellent control when refining margins, proximal boxes and internal cavity anatomy. The rounded shoulder design helps minimise sharp internal angles which can weaken ceramic restorations.
Manufactured in Germany by Frank Dental, this high-quality dental diamond bur delivers smooth cutting performance, excellent concentricity and reduced vibration for improved clinician control and patient comfort. The premium diamond coating ensures consistent cutting efficiency and predictable preparation quality throughout restorative procedures.
