Foredom 3'' Sanding Disc Ceramic Purple Psa 120 Grit

Description:

3" Ceramic Purple PSA Sanding Disc 120 Grit is designed for intermediate-level smoothing and refined shaping in dental laboratory workflows. Manufactured using advanced ceramic abrasive technology, it offers enhanced durability, consistent cutting efficiency, and long service life�features essential for precise dental restorative adjustments. The 120-grit surface provides balanced material removal, making it ideal for refining contours after rough grinding, eliminating moderate scratches, smoothing transitions, and preparing surfaces for finer finishing or polishing steps. It performs exceptionally well on dental alloys, zirconia and ceramic structures, acrylic dentures, and thermoplastic materials. Its PSA backing ensures quick, clean application to mandrels or sanding discs, providing a secure hold that supports smooth rotational action. This prevents slippage, improves operator control, and minimizes vibration during use. The generous 3" diameter allows for broader surface coverage, enhancing efficiency when finishing large restorations or appliance components. The ceramic abrasive particles maintain sharpness longer than standard abrasives, giving the disc a prolonged working life and reducing the frequency of replacement. This consistency supports predictable finishing outcomes and streamlined laboratory workflow. The disc is engineered to operate cool, reducing thermal risk to heat-sensitive substrates such as acrylics and ceramics. It resists loading, even when used on softer materials, ensuring continuous, even abrasion throughout the finishing process. Ideal as a transitional step between coarse shaping and fine finishing, the 3" Ceramic Purple PSA 120 Grit Sanding Disc is an essential tool for producing smooth, uniform, and anatomically accurate dental restorations.
