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 precision-shaped dental instrument engineered to produce accurate geometric features within cavity preparations and restorative designs. The inverted-cone profile allows clinicians to create defined internal angles, retention grooves, and undercut forms that support mechanical stability for amalgam and composite restorations. Because the bur cuts with its lateral and peripheral surfaces, it enables efficient removal of unsupported enamel and smooth shaping of axial-pulpal line angles. The medium-grit diamond abrasive contributes to controlled removal rates, preventing over-cutting or loss of structural detail in the preparation. With a 2.8 mm head diameter and 5.5 mm head length, the bur provides adequate reach while preserving tactile feedback. The standard 2.35 mm shank ensures compatibility with contra-angle handpieces used for precision restorative work, including minimally invasive cavity design and structural refinement of preps prior to adhesive procedures. In operative dentistry, this bur is especially effective when adjusting internal walls in Class I and II preparations or when preparing occlusal surfaces for bonded restorations that require specific geometry. In prosthodontics, it can be used to shape internal relief areas on provisional units or adjust the fit of temporary restorations. Diamond-coated inverted-cone burs also allow for micro-retentive texturing on ceramic or composite surfaces before bonding, provided they are used with appropriate irrigation to maintain temperature control. By incorporating this instrument into routine operative workflows, clinicians achieve consistent internal shaping while maintaining fine control over surface texture and cavity morphology. The medium-grit finish creates a uniform substrate ideal for adhesive penetration, contributing to the longevity and integrity of the final restoration.
