Foredom Diamond Polishing Disc 6'' Dia. 180grit .5'' Ah

Description:

Diamond Polishing Disc 6'' dia. 180Grit .5'' AH is a fine-medium abrasive disc used extensively in dental laboratories for precise surface refinement and preparation of restorations. The 180-grit diamond surface provides gentle yet effective abrasion, making it ideal for smoothing ceramics, zirconia structures, metal restorations, acrylic appliances, and composite materials. The 6-inch diameter allows wide coverage across prosthetic surfaces, enabling technicians to achieve uniform finishing with minimal repositioning. Its stable, vibration-controlled rotational performance ensures consistent results, especially during delicate contouring tasks. The .5-inch arbor hole ensures compatibility with commonly used polishing systems, maintaining alignment under steady workloads. This disc is typically applied after medium-grit abrasives such as 120-grit discs. It removes residual scratches, reduces surface graininess, and further defines anatomical features before moving to fine polishing stages. Its diamond bonding enhances durability and heat resistance, ensuring that fragile materials like ceramic and zirconia remain structurally secure during use. Dental professionals rely on this disc for tasks such as refining occlusal anatomy, smoothing crown contours, adjusting implant prosthetic surfaces, and preparing restorations for high-gloss finishing. The controlled abrasive level reduces risk of over-contouring while still producing a clean, uniform surface. In the restorative workflow, this 180-grit disc is an essential intermediate finishing tool. It contributes significantly to achieving balanced esthetics, optimal function, and long-term durability in dental prosthetics.
