The CGW 51239 5-inch diameter sanding disc is designed for high-performance surface finishing tasks on metal and similar substrates. This disc uses a 320-grit aluminum oxide abrasive film mounted on a durable hook-and-loop (H&L) backing, providing an easy, quick change and reliable cling to compatible sanding tools. The film backing is described as strong and pliable, with a .003 Mylar layer that contributes to a consistent finish and longer life compared with standard paper-backed discs. The film construction is positioned for both dry and wet sanding applications, offering flexibility across finishing workflows.
Key construction features include the hook-and-loop attachment system for rapid disc changes and stable mounting during operation, along with a formulation intended to deliver a smooth, uniform cut and a longer service life relative to traditional paper discs. The 320-grit aluminum oxide abrasive is suitable for refining surfaces, removing minor imperfections, and preparing metal workpieces for subsequent coatings or treatments. This disc is packaged in a box quantity of 100, making it suitable for shops that require steady supply and consistent grit availability.
When selecting this disc, ensure compatibility with standard 5-inch hook-and-loop sanding tools and confirm the grit and hardness level align with your current finishing regimen. The disc’s relatively high durability and fast-cutting characteristics make it appropriate for intermediate to fine finishing steps on metal and similar substrates, especially in dry or wet sanding scenarios where a longer-lasting film backing can reduce downtime and replacement frequency.
