These discs are designed with universal, 12-hole random orbital sanding (ROS) technology, featuring Hook and Lock backing. What sets these discs apart are the breakthrough innovations that enhance performance, extend sanding life, and increase productivity. Made with a premium ceramic blend, these discs are specifically formulated to remove material faster than other sanding discs, while also offering an exceptionally long sanding life. The inclusion of Clog-SHIELD, Diablo's own grinding agent blend, reduces loading and maximizes productivity. Additionally, the superior grit-to-backing bond, known as ENDURA-BOND, provides these sanding discs with exceptional durability and a longer lifespan. The premium ceramic blend is a testament to its superior quality, ensuring fast material removal and extended sanding life. The unique 12-hole pattern allows for a one-size-fits-all design, compatible with both 5 and 8-hole sanders, ensuring fast and precise alignment. The premium hook and lock backing enable repeated attachment and removal of discs, providing a consistent and secure connection. To further enhance productivity, these discs are coated with Clog-SHIELD, a high-performance separate coating that reduces pitch build-up and clogging. This ensures maximum efficiency throughout your refinishing project. The specialized high-strength resin, known as ENDURA-BOND, provides a superior grit-to-backing bond, resulting in extreme durability. These discs are suitable for use with orbital and DA sanders, making them versatile for various projects. They can be used on a range of materials, including wood, metal, and plastics.
