The CGW 49801 5" Dia 400-Grit Gold Aluminum Oxide PSA DWT Sanding Disc is a high-performance abrasive designed for efficient material removal on flat surfaces. This 5-inch PSA (pressure-sensitive adhesive) disc features a gold weight paper backing engineered for tear resistance, helping to maintain stability during grinding and reduce disc snags. The grain is aluminum oxide with a heat-treated composition and a full phenolic bond, which supports a uniform scratch pattern and consistent wear across the disc’s life. An open-coat construction enhances dust tolerance and enables a faster cut rate, contributing to longer disc life in demanding sanding tasks.
Designed for use in dry sanding applications, this disc blends strong backing with stearated paper and a heat-treated aluminum oxide grain to deliver a predictable and repeatable scratch pattern. The combination supports extended wheel life while maintaining aggressive cutting action, making it well-suited for metal and similar hard surfaces where a finer finish is not required. The 400-grit level places this disc in a mid-fine range, appropriate for surface leveling, deburring, and preparing substrates for subsequent coatings or treatments.
Compatibility and packaging details indicate a 5" diameter, PSA attachment, with a C-weight (hardness) backing that helps maintain disc rigidity under load. The product is offered in a package of single discs, with a box quantity of 100 in some configurations, making it practical for replacement cycles in shop and facility maintenance settings. When selecting discs, consider the substrate material, desired finish, and the adhesive’s compatibility with your sanding tool’s pad to ensure secure attachment and consistent performance over the disc’s service life.
