Product Description:

Introducing our versatile and high-performing 3M Hookit Sanding Discs. These discs are designed to cater to a wide range of applications, with a primary focus on efficient stock removal. They are incredibly effective on various substrates, including metals, composites, gelcoat, and whitewood.

What sets our Hookit Sanding Discs apart is the film backing, which offers superior tear resistance compared to traditional paper discs. This enhanced durability ensures that the discs can withstand rigorous use while maintaining excellent edge retention. For optimal results, we recommend using these discs in conjunction with our reliable 3M Elite Random Orbital Sanders.

For workspaces where adhesive-backed discs may be prone to contamination by dust or dirt, we offer a complete line of hook-and-loop style 3M Hookit discs. These discs are specifically designed to address this concern, providing a reliable solution. In addition, Hookit discs are known for delivering finer finishes compared to adhesive-backed discs, making them ideal for applications where a more refined outcome is desired.

Our Hookit sanding discs conveniently attach to a hook-and-loop backup disc pad (sold separately), allowing for easy and secure installation. When it's time to remove the disc, it can be done cleanly and effortlessly. The best part is that these discs can be reused multiple times throughout their abrasive life, providing excellent value for money.
