  • DESCRIPTION

7500 Sianet 6″ Net Sanding Disc – 400 Grit Ceramic Abrasive

The 7500 Sianet 6″ Sanding Disc (400 Grit) features revolutionary open-net technology that sets a new standard for workplace health and efficiency. Unlike traditional paper discs with punch holes, the entire surface of the Sianet disc allows for airflow. This full-surface extraction capability removes up to 95% of sanding dust the moment it is created. This not only keeps the air cleaner for the operator but also prevents dust knots from forming on the surface, ensuring a pristine finish on wood, drywall, and automotive paints without the hassle of constant cleanup.

Ceramic Grain Technology for Superior Cut

Engineered for performance, this disc utilizes a premium Ceramic Aluminum Oxide grit. Ceramic grains are significantly harder and sharper than standard abrasives, providing a faster cut rate and a more consistent scratch pattern. At 400 grit, this disc is exceptionally effective for fine sanding and “keying” surfaces—preparing primers, old lacquers, or solid surface materials for the final topcoat. The ceramic grain creates a uniform matte finish that maximizes adhesion while minimizing the risk of deep scratches that require rework.

Clog-Free Durability Across Materials

The 7500 Sianet is designed to resist clogging, a common failure point in fine grit sanding. The open mesh structure prevents dust from packing between the grains, allowing the disc to maintain its cutting efficiency long after a standard paper disc would have failed. This durability makes it a cost-effective solution for a wide range of applications, from flattening lightweight construction walls and sanding mineral materials to finishing hard woods and smoothing UV lacquers. With 50 discs per box, high-volume shops can rely on Sianet for consistent, long-lasting performance.
