Foredom Diamond Polishing Disc 4'' Dia. 180grit .5'' Ah

Description:

The Diamond Polishing Disc 4" dia. 180Grit .5" AH is a fine-medium abrasive disc designed for precision finishing and surface refinement during the later stages of dental restoration fabrication. Featuring a 180-grit diamond polishing surface, it provides gentle yet effective abrasion ideal for smoothing previously contoured ceramic, composite, or zirconia restorations. This disc is used to reduce surface roughness, refine anatomical features, soften sharp transitions, and prepare restorations for high-sheen polishing. It is particularly effective for smoothing occlusal surfaces, adjusting marginal ridges, refining veneer edges, and preparing aesthetic zones for micro-polish stages. The 4-inch diameter ensures excellent control and wide working coverage, making it suitable for crowns, bridges, multi-unit structures, and full-arch restorations. The .5-inch arbor hole ensures proper fit on standard laboratory lathes and polishing motors, allowing safe and stable rotational performance. The 180-grit diamond particles create a mild polishing action that removes marks left from coarser abrasives without altering the morphology of the restoration. This reduces technician workload by decreasing the number of steps needed before final polishing. Additionally, the disc is engineered to minimize heat buildup, maintaining material integrity and reducing risks like thermal stress or microfracturing in ceramics. Its robust construction ensures longevity, maintaining cutting efficiency even during repeated use. The low-vibration performance enhances comfort, control, and precision, essential for delicate finishing tasks. With dependable performance, refined abrasion, and excellent usability, this disc plays an essential role in delivering smooth, well-finished dental restorations ready for final polishing and glazing.
