Foredom Diamond Bur Inv. Cone M 3mm L 4mm D 2.35mm

Description:

The Diamond bur Inv. Cone M 3mm l 4mm d 2.35mm is a reliable medium-grit dental bur designed for clinicians who require precise control over internal cavity modifications and structural refinement. With a 3 mm diameter and 4 mm head length, it provides broader engagement than smaller inverted-cone burs, making it well-suited for shaping moderate-sized cavity preparations, smoothing internal surfaces, and forming defined retention contours. The inverted-cone configuration enables efficient lateral cutting, allowing clinicians to refine axial walls, create mechanical undercuts where clinically appropriate, and establish uniform pulpal floor morphology. Its medium-grit diamond abrasive delivers predictable cutting action, supporting balanced material removal while preventing over-cutting�a critical factor in preserving tooth structure during operative procedures. The bur�s dimensions make it particularly effective in Class I and II cavity preparations, internal adjustments to onlay preparations, and modifications to restorative designs that require consistent internal geometry. In prosthodontics, it is useful for adjusting internal ceramic surfaces prior to bonding or refining contact areas within provisional restorations. The bur�s geometry supports shaping composite and ceramic materials with precision while maintaining a controlled tactile response. Adequate water irrigation ensures thermal regulation and maintains the integrity of both tooth structure and restorative materials. The 2.35 mm shank is compatible with most contra-angle handpieces used in precision restorative work. After using this bur to achieve internal shaping, clinicians typically continue with finer instruments when a smoother surface is required for bonding or finishing. Its versatility, durability, and shaping accuracy make it a dependable tool for routine restorative procedures.
