Foredom Diamond Polishing Disc 4'' Dia. 400grit .5'' Ah

Description:

Diamond Polishing Disc 4" dia. 400Grit .5" AH is a super-fine, high-precision polishing disc designed for the last stages of dental restoration finishing. With its extra-fine 400-grit diamond abrasive, this disc delivers an extremely smooth surface, removing even the smallest surface irregularities left from previous polishing stages. This disc is essential for achieving a near-gloss finish on zirconia crowns, ceramic veneers, composite restorations, hybrid ceramics, and both anterior and posterior prosthetics. Its very fine abrasive action ensures that delicate anatomical features are preserved while enhancing the aesthetic quality of the restoration�s surface. The 4-inch diameter makes it effective for large restorations, multi-unit bridges, and full-arch designs. The .5-inch arbor hole ensures secure mounting on standard laboratory motors, supporting stable, controlled operation ideal for delicate finishing. The 400-grit polishing action prepares the restoration for glazing, paste polishing, or buffing. It significantly enhances surface smoothness, increasing light reflection and improving the natural appearance of dental ceramics. Because it removes minimal material, it is exceptionally safe for detailed finishing, margin refinement, and aesthetic contour finalization. Its diamond-coated surface provides consistent polishing efficiency and long service life, even under frequent professional use. The disc�s design minimizes vibration, allowing technicians to maintain excellent control, particularly in high-precision aesthetic cases. Whether used as the final step before gloss polishing or as a standalone finishing tool, this disc ensures restorations meet the highest aesthetic and functional standards. It is indispensable for laboratories seeking exceptional surface quality and reliable, professional finishing results.
