Foredom Diamond Bur Inv. Cone M 2.5mm L 2.5mm D 2.35mm

Description:

Diamond bur Inv. Cone M 2.5mm l 2.5mm d 2.35mm is a precision-focused rotary dental instrument specifically designed for shaping intricate internal preparation features in operative and restorative dentistry. Its inverted-cone geometry allows clinicians to create defined undercuts, refine axial-pulpal angles, and smooth internal wall surfaces within cavity preparations. The medium-grit diamond coating offers a controlled cutting rate, ensuring effective shaping without sacrificing tactile sensitivity or risking excessive removal of tooth structure. With a compact 2.5 mm diameter and 2.5 mm head length, this bur excels in fine-detail applications such as refining Class I and II preparations, adjusting internal walls for improved restorative adaptation, and preparing small cavities for adhesive procedures. The instrument�s shape allows efficient lateral cutting, providing smooth transitions between internal surfaces, and is especially beneficial when enhancing mechanical retention before composite placement. In prosthodontic and restorative workflows, the bur is also used for micro-adjustments to provisional restorations, internal relief contouring, and precise shaping of small ceramic or composite zones during chairside adjustment. Its medium-grit finish creates a uniform microtexture suitable for bonding, while avoiding deep abrasions that require extensive refinement. The 2.35 mm shank ensures compatibility with standard contra-angle handpieces, enabling controlled, ergonomic use. Adequate irrigation is recommended to control temperature and maintain cutting efficiency. This bur is typically followed by finer abrasives when a smoother internal surface is desired. Its precision, versatility, and dependable cutting characteristics make it a valuable tool for routine operative procedures.
