Product Details

Description:

The 3" Ceramic Purple PSA Sanding Disc 220 Grit is engineered for fine finishing, detailed smoothing, and pre-polish preparation in the dental laboratory. Designed with advanced ceramic abrasive grain technology, it delivers exceptional durability, consistent abrasion, and smooth cutting performance across a wide range of restorative materials. Its 220-grit rating makes it ideal for removing light scratches, blending contours, refining occlusal surfaces, smoothing appliance bases, and preparing restorations for high-shine polishing compounds. It is commonly used on metal frameworks, zirconia, ceramic restorations, acrylic dentures, orthodontic components, and thermoplastic appliances. The PSA backing ensures strong adhesion to disc pads, providing stability and consistent rotational control. This allows technicians to achieve uniform abrasion without chatter or slippage, contributing to high-quality surface refinement. The 3" diameter offers excellent coverage, making it suitable for broad finishing zones while still maintaining controlled precision. Ceramic abrasive grains offer superior longevity compared to aluminum oxide, meaning the disc retains sharpness longer, stays effective under continuous use, and supports efficient workflow. Its cool-cutting characteristics reduce heat buildup, protecting materials from thermal stress and preventing problems such as warping, microcracking, or acrylic whitening. This disc is typically used after 120 grit or similar abrasives to remove fine lines, perfect contours, and prepare surfaces for final polishing. Whether used for metal-ceramic restorations, acrylic prosthetics, or intraoral appliance adjustments, the 3" Ceramic Purple PSA 220 Grit Sanding Disc delivers reliable, predictable, and high-quality finishing results in dental laboratories.
