The CGW 51507 5%22 dia 400-grit Extreme Purple Ceramic PSA DWT Sanding Disc is a high-performance abrasive designed for demanding material removal tasks. This 5" PSA disc uses a ceramic grain and open coat for aggressive cutting with a focus on efficient material removal, suitable for quick stock removal on metals and other compatible substrates. The purple ceramic grain is paired with a stearate-coated surface to help resist loading and clogging during prolonged use, helping maintain consistent cutting action across the disc’s life.
Construction details include a C-weight latex paper backing that provides a balance of durability and flexibility, enabling secure adherence to a flat or contoured sanding pad. The PSA ( Pressure-Sensitive Adhesive ) backing simplifies mounting and replacement, making it convenient for continuous workflow. With a 400-grit size, this disc is positioned for fine to medium finishing where a good surface texture is required without extensive smoothing or glazing, and the ceramic formulation is chosen to deliver both longevity and a strong removal rate.
Typical applications include metal deburring, edge chamfering, and surface finishing where rapid material removal is balanced with finish quality. When using resin-based or high-temperature processes, consider disc loading and workpiece material to optimize performance. Each package contains 100 discs, and the disc is specified as 5" diameter with PSA mounting to fit standard 5" sanding tools and compatible backings. Regular inspection and proper storage away from moisture help preserve the adhesive performance and disc integrity over time.
