Foredom Diamond Polishing Disc 4'' Dia. 220grit .5'' Ah

Description:

Diamond Polishing Disc 4" dia. 220Grit .5" AH is a fine-grit polishing solution engineered for advanced finishing of dental restorations made from zirconia, ceramic, composite resin, and hybrid materials. With its 220-grit diamond abrasive coating, it provides delicate smoothing and detailed refinement during the later finishing stages. This disc is used to eliminate micro-scratches, enhance anatomical definition, and produce a uniform surface texture that transitions seamlessly into gloss polishing. It is ideal for veneers, crown margins, occlusal refinement, pontic surfaces, and delicate aesthetic adjustments, supporting technicians in producing high-quality restorations with lifelike morphology. At 4 inches in diameter, the disc offers comfortable handling, broad coverage, and easy access to larger surfaces. The .5-inch arbor hole ensures compatibility with standard laboratory polishing systems, providing stable and controlled rotation. Low vibration and balanced construction allow technicians to maintain accuracy and avoid excessive reduction of critical anatomy. The 220-grit level is particularly valuable for smoothing surfaces after medium abrasives have been used. It gently refines texture without compromising the structural integrity of ceramics or the precise contours developed in earlier stages. Heat-minimizing characteristics further protect delicate materials such as lithium disilicate. Built with premium diamond particles, the disc maintains cutting efficiency and durability throughout its lifespan. Its consistent performance improves workflow efficiency, reduces finishing time, and contributes to a predictable polishing sequence that leads to high-gloss results. For laboratories focused on both aesthetics and precision, this 220-grit disc is an essential tool in the restorative finishing process.
