PRODUCT FAQ

What makes the 3M™ Cubitron™ II Hookit™ Film Disc 775L different from other sanding discs?

The Cubitron™ II 775L uses advanced precision-shaped grain technology, which cuts faster and lasts longer than conventional abrasives. It provides a very consistent finish and reduces heat buildup, making your work smoother and more efficient!
What surfaces can I use this film disc on?

These discs are great for a variety of materials! They’re ideal for metals, composites, paint preparation or finishing applications, wood, and even plastics—making them super versatile in both automotive and industrial settings.
How does the Hookit™ attachment system work?

The Hookit™ backing is just like Velcro! It lets you easily attach the disc to your sanding tool’s backup pad. When you need to change discs or reuse one later, it peels off cleanly with no mess—quick changes mean less downtime!
What does “1000+ grit” mean here?

“1000+ grit” means it’s an ultra-fine sanding disc perfect for delicate surface finishing tasks such as blending or prepping before final coatings. It’s especially useful when you need smoothness with minimal scratching!
How many discs come in a carton or case when I order?

Each carton contains 50 discs. If you go for a full case, there are five cartons inside—that’s 250 discs total—so you'll have plenty on hand for bigger projects!

Extended Grade Range for Versatile Applications

Now featuring an expanded grade range up to 1000+, these discs are engineered to accommodate a wide array of sanding and finishing tasks. Whether you require aggressive stock removal or are focused on achieving a refined, smooth finish, these discs deliver reliable performance across the spectrum of applications.

Effective on Multiple Substrates

Designed for versatility, these discs perform exceptionally well on a variety of materials, including metals, composites, all types of wood, as well as painted surfaces, primers, and other coatings. This adaptability makes them an excellent choice for professionals working in industries such as automotive, woodworking, metal fabrication, and more.

Durable Film Backing for Enhanced Performance

The discs are constructed with a robust film backing that offers superior tear resistance compared to traditional paper-backed discs. This enhanced durability ensures that the discs maintain their integrity and edge retention, even during demanding wet or dry sanding operations. As a result, users benefit from longer-lasting abrasives and consistent results.

Optimized for 3M Xtract Random Orbital Sanders

For optimal performance and efficiency, it is recommended to use these discs with 3M Xtract Random Orbital Sanders. This combination maximizes dust extraction, improves surface finish quality, and extends the life of the abrasive, helping you achieve professional results with less effort.

3M Hookit System for Clean, Reusable Attachment

The comprehensive line of 3M Hookit discs is specifically designed for environments where adhesive-backed discs may be compromised by dust or debris. The Hookit system utilizes a convenient hook-and-loop attachment method, allowing discs to be easily attached, removed, and reused throughout their lifespan. This not only enhances cost-effectiveness but also reduces downtime during disc changes.

Achieve Finer Finishes with Less Aggression

Compared to 3M Stikit discs, Hookit discs are engineered to be less aggressive, making them ideal for applications where a finer, more controlled finish is desired. Their reusable nature and clean removal further contribute to their value, making them a preferred choice for professionals seeking both quality and efficiency.
