Foredom Diamond Polishing Disc 4'' Dia. 240grit .5'' Ah

Description:

Diamond Polishing Disc 4" dia. 240Grit .5" AH is a high-precision fine-grit polishing disc developed for the advanced finishing of dental restorations. With its 240-grit diamond surface, it provides delicate smoothing to remove fine imperfections and refine surface quality before final gloss polishing or glazing. This disc is especially suitable for finishing ceramic veneers, anterior crowns, full-contour zirconia, composite resin restorations, and implant-supported prosthetics. The fine-grit texture helps create a natural surface appearance by refining transitions, highlighting occlusal details, and improving edge clarity without producing deep scratches. The 4-inch diameter offers ample working area, making it efficient for multi-unit restorations and full-arch cases. The .5-inch arbor hole ensures proper fit on laboratory polishing motors, providing balanced, stable rotation that supports precise and controlled finishing. The 240-grit abrasive removes minimal material, preserving critical contours and delicate morphological features established during shaping. Its low-heat performance prevents thermal stress on ceramic surfaces, which helps maintain structural stability and reduces the risk of cracks. Durability is a key advantage, as the diamond-coated surface maintains its abrasive strength over long periods of use. Its smooth handling and reduced vibration offer technicians excellent maneuverability, ensuring refined finishes even in intricate areas. Whether used for delicate smoothing or as a final preparation before high-gloss polishing, this disc contributes to efficient workflows and superior restoration aesthetics. It is a staple tool in laboratories that prioritize accuracy, comfort, and flawless finishing.
