CGW 51060 5" Dia 400-Grit Green Premium Aluminum Oxide PSA DWT Film Sanding Disc

CGW 51060 5" Diameter 400-Grit Green Premium Aluminum Oxide PSA DWT Film Sanding Disc is designed for versatile finishing tasks on metal and other hard substrates. This 5-inch disc uses a PSA (pressure-sensitive adhesive) backing to provide quick, clean attachment to compatible sanding backslices and machines, enabling efficient disc changes during work. The disc’s film construction offers a smooth, consistent finish and greater durability under both dry and wet sanding conditions, helping to extend service life compared with traditional paper discs.

A key feature is the film backing with a .003 Mylar substrate, which provides a balance of rigidity and pliability. This backing supports strong, uniform stock removal while resisting tearing, contributing to a predictable cut across the contact surface. The 400-grit aluminum oxide grain is suitable for fine finishing and blending, producing a finer surface texture that is often preferred for preparing metal surfaces prior to polishing or coating applications. Disc performance can translate into reduced rework and longer cycle times in appropriate workflows.

Typical usage involves discing metal components, automotive parts, and other hard materials where a smooth, consistent finish is required. Users should verify compatibility with standard 5-inch PSA sanding systems and replace discs as the abrasive wears to maintain consistent results. Each package is specified as containing individual discs, with a box quantity of 100, to support bulk replacement in production or maintenance environments.
