PRODUCT FAQ

What grit level is the 3M Cubitron II Hookit Disc 950U?

The 80+ F-weight grit provides a medium-coarse abrasive surface that's ideal for general purpose sanding and material removal on a wide variety of surfaces.
Will this disc fit my 5-inch random orbital sander?

Yes! The 5-inch size is designed to work with standard 5-inch sanders, and the Hookit attachment system ensures a secure, reliable fit every time.
How many discs do I get in a typical order?

Each carton contains 50 discs, and when you order a case, you're getting 250 discs total—that's five cartons of dependable sanding power.
What makes Cubitron II different from standard abrasives?

Cubitron II features advanced ceramic grain technology that stays sharper longer, cuts faster, and generates less heat than conventional abrasives, giving you better performance and longer disc life.
Can I use these discs on both wood and metal?

Absolutely! The 950U is versatile and works great on multiple materials including wood, metal, composites, and painted surfaces, making it a smart choice for diverse job requirements.

Fast Cutting Performance Without Buildup

The 3M Cubitron II Hookit Disc 950U incorporates advanced Precision-Shaped Grain technology, a sophisticated abrasive innovation designed to progressively fracture during use. As the grain breaks down, it systematically exposes fresh, sharp cutting edges that maintain optimal cutting efficiency throughout the product's operational lifespan. This continuous regeneration of cutting surfaces enables the disc to sustain remarkably high material removal rates while simultaneously minimizing substrate temperature rise—a critical advantage when working with heat-sensitive materials such as aluminum. The grains are strategically distributed in an open-coat configuration, which effectively prevents abrasive particle accumulation on the work surface. This design approach proves particularly beneficial when processing aluminum and other materials prone to clogging, resulting in superior cutting speeds and extended disc longevity compared to conventional abrasive alternatives.

Aggressive Material Removal with Superior Surface Quality

The 3M Cubitron II Hookit Disc 950U represents a comprehensive engineering solution that balances aggressive cutting action with refined finishing characteristics. By integrating premium grain technology, robust structural design, and a precision-engineered backup pad attachment system, this disc delivers powerful material removal capabilities while producing consistently smooth, uniform surface finishes. This combination makes it particularly well-suited for demanding industrial applications including panel finishing and frame preparation work.

Convenient Hook-and-Loop Attachment System

This disc utilizes the proprietary Hookit attachment method, specifically engineered for work environments where traditional adhesive-backed discs are susceptible to contamination from dust, debris, or airborne particles. The hook-and-loop design enables quick, secure attachment to compatible backup pads (available separately) on random orbital sanders, while allowing for effortless removal and repeated reuse. The discs maintain their abrasive effectiveness across multiple applications, maximizing material value and reducing waste throughout their service life.
