Foredom Diamond Bur Inv. Cone M 2.8mm L 5.5mm D 2.35mm

Description:

The Diamond bur Inv. Cone M 2.8mm l 5.5mm d 2.35mm is a versatile inverted-cone dental bur engineered to deliver precise internal shaping and structural refinement in operative and restorative procedures. Its 2.8 mm diameter and 5.5 mm head length provide enhanced reach within deeper cavity preparations while preserving the ability to refine intricate internal surfaces. The medium-grit diamond abrasive strikes an ideal balance between cutting efficiency and smoothness, enabling clinicians to shape internal angles, smooth cavity floors, and establish retention features without compromising control. Because the inverted-cone shape naturally creates defined internal contours, this bur is especially useful when preparing cavities for composite or amalgam restorations that require mechanical retention. It is frequently used to smooth axial walls, fine-tune pulpal floors, and remove unsupported enamel while creating a cohesive geometry for restorative adaptation. In larger preparations, the extended head length enhances access and visibility, allowing clinicians to maintain precise shaping even in deeper operative environments. Beyond operative dentistry, this bur is also practical for adjusting provisional restorations, refining internal zones of ceramic units before try-in, and shaping composite materials during chairside corrections. The medium-grit texture creates a surface suitable for adhesive bonding while minimizing the need for excessive additional finishing. The 2.35 mm shank ensures compatibility with standard contra-angle handpieces, and consistent water irrigation is recommended to maintain temperature control and maximize cutting performance. Often used prior to fine-grit finishing burs, this instrument offers reliable performance and excellent tactile feedback for routine restorative shaping.
