Foredom Diamond Polishing Disc 4'' Dia. 120grit .5'' Ah

Description:

The Diamond Polishing Disc 4" dia. 120Grit .5" AH is a versatile medium-grit polishing disc tailored for dental technicians seeking dependable performance during intermediate finishing stages. With its 120-grit diamond abrasive surface, this disc delivers a balanced level of abrasion that effectively refines contours while beginning to smooth surface irregularities left from coarse grinding. This disc is widely used for adjusting ceramic occlusal surfaces, refining cusp tips, smoothing veneer edges, refining interproximal contours, and preparing restorations for high-gloss polishing. It works efficiently on zirconia, lithium disilicate, ceramic hybrids, composite resin restorations, and provisional materials. The 4-inch diameter ensures broad, even coverage, enabling technicians to polish large restorations or multiple units without losing control or precision. Paired with a .5-inch arbor hole, the disc mounts securely to most standard dental laboratory motors, providing stable rotation and consistent handling throughout use. Because of its optimal abrasive level, the 120-grit disc reduces the risk of deep scratches, making the subsequent fine finishing stages smoother and faster. It offers controlled heat dispersion, minimizing the risk of microcracking or compromising ceramic integrity. Its durable diamond particles are firmly bonded to the disc surface, giving it a long working lifespan even under continuous or heavy usage. The disc�s low vibration design improves technician comfort and helps maintain accurate polishing angles, which is essential for producing natural anatomical surfaces and lifelike morphology. Overall, the Diamond Polishing Disc 120Grit supports efficient workflow, precise contour refinement, and high-quality finishing results for dental laboratories.
