Foredom Diamond Polishing Disc 8'' Dia. 220grit .5'' Ah

Description:

Diamond Polishing Disc 8" dia. 220Grit .5" AH is engineered for dental technicians who require reliable medium-coarse abrasion when contouring restorative materials. The 220-grit diamond coating provides enough cutting efficiency to reshape ceramic and zirconia surfaces without deep scratching, making it suitable for intermediate refinement stages after initial reduction. The 8-inch diameter offers a wide working area, enabling smoother, uninterrupted strokes and uniform pressure distribution during polishing operations. This disc is commonly used in dental laboratories for adjusting full-ceramic crowns, zirconia frameworks, composite plates, and acrylic prosthetic components. Its durable bonded diamond grains offer excellent longevity even under continuous rotational use. The .5-inch arbor hole allows stable attachment to bench polishers, minimizing vibration and helping technicians maintain precision while working with fragile prosthetic designs. During fabrication, the disc allows technicians to correct high spots, refine margins, adjust occlusal contours, or achieve overall shape harmonization before moving on to finer polishing discs. Its balance between cutting speed and smooth control reduces the risk of chipping, overheating, or micro-cracking, especially on ceramic and zirconia surfaces. Easy to handle and compatible with most polishing motors, the Diamond Polishing Disc 8" dia. 220Grit .5" AH is an essential laboratory accessory for achieving predictable intermediate surface refinement. It supports efficient workflow while ensuring restorations are shaped with accuracy before entering the final polishing stages.
