Foredom Diamond Bur Inv. Cone M 4mm L 10mm D 2.35mm

Description:

The Diamond bur Inv. Cone M 4mm l 10mm d 2.35mm is engineered for advanced restorative applications where deep access, broad reduction capability, and precise internal shaping are essential. Its large 4 mm diameter and extended 10 mm cutting length provide clinicians with significant reach and surface coverage, enabling efficient shaping of large cavities, extensive carious lesion removal, and refinement of deeper structural areas that smaller burs cannot adequately address. The inverted-cone geometry is highly effective for forming mechanical retention features, generating flat internal floors, and refining axial walls in complex restorative preparations. Its larger head size improves stability and reduces vibration during cutting, enhancing precision and operator control. The medium-grit diamond surface provides a balanced cutting action that allows for rapid reduction without compromising smoothness or producing excessive heat. Designed with a 2.35 mm shank, the bur fits securely into standard contra-angle handpieces, delivering consistent rotational performance. Its durable materials withstand repeated sterilization cycles, preserving the sharpness and abrasive qualities of the diamond coating. This reliability makes it especially useful in high-volume or intensive clinical environments. Clinically, this bur excels in demanding restorative tasks such as shaping large occlusal and proximal preparations, adjusting indirect restoration cavities, and preparing deep undercuts for mechanical retention. It is also effective for refining composite and amalgam restorations, adjusting internal contours of prosthodontic preparations, and preparing surfaces for adhesive bonding. Overall, this bur serves as a high-capacity instrument for clinicians who require precision, depth capability, and consistent cutting performance during extensive restorative procedures.
