CGW 49790 5" Dia 40-Grit Gold Aluminum Oxide PSA DWT Sanding Disc is designed for efficient material removal on flat or contoured surfaces. This abrasive disc uses a 5-inch diameter PSA (pressure-sensitive adhesive) backing, enabling quick, spray-free attachment to compatible sanding tools. The disc’s open-coat construction helps deliver a fast-cutting action while maintaining long life, making it suitable for extended use on a variety of metal and wood applications where controlled stock removal is needed.
Construction details contribute to consistent performance: the disc features heat-treated aluminum oxide grain bonded to a full phenolic resin, which supports a uniform scratch pattern and predictable wear. A stearated paper backing reduces clogging and enhances handling, while a strong tear-resistant substrate aids durability during repeated mounting and use. The combination of these materials is intended to balance aggressive material removal with surface finish quality on standard workpieces.
This disc is sized for 5-inch sanding systems and is packaged per disc with a box quantity of 50, making it convenient for maintenance shops that require steady availability of abrasives with consistent performance. Suitable use cases include metal and wood surface preparation where a 40-grit, medium-cut option is appropriate, and where PSA discs are preferred for quick changes and reduced setup time. Always verify compatibility with your tool’s mounting system and follow standard safety practices during operation.
