PRODUCT FAQ

What grit level is the 3M Cubitron II Hookit Disc 950U, and what surfaces can it handle?

The 180+ F-weight grit makes this disc ideal for medium to fine finishing work on a variety of surfaces including metal, composite, and painted substrates. It's versatile enough for both general purpose sanding and more refined finishing applications.
Will this disc work with my standard random orbital sander?

Yes! The 5-inch Hookit design is compatible with most standard 5-inch random orbital sanders. The Hookit backing system provides a quick, secure attachment without the need for traditional adhesive or screws.
How many discs do I get, and how are they packaged?

You'll receive 250 discs total per case, which is conveniently organized into 5 cartons of 50 discs each. This bulk packaging is perfect for shops that want to keep well-stocked without frequent reordering.
What makes Cubitron II technology better than traditional abrasives?

Cubitron II features advanced grain technology that fractures during use to continuously expose sharp cutting surfaces, which means longer life, faster cutting, and less dust compared to conventional abrasives. You'll get better performance and efficiency on every job.

Cuts Fast Without Loading

The 3M Cubitron II Hookit Disc 950U incorporates advanced Precision-Shaped Grain technology, a proprietary innovation developed by 3M that systematically fractures during use to continuously expose fresh, sharp cutting edges. This engineered fracturing process enables the disc to maintain an impressively high cutting velocity throughout its operational lifespan, while simultaneously minimizing substrate temperature buildup during extended use. The grain structure is distributed in an open-coat configuration that effectively prevents abrasive particle accumulation—a critical consideration when working with softer metals such as aluminum. The synergistic combination of these design elements produces an abrasive solution that delivers superior cutting performance and extended product longevity compared to conventional alternatives.

Aggressive Cut, Smooth Finish

The 3M Cubitron II Hookit Disc 950U represents an integration of material science, structural engineering, and surface finishing technology. From the precision grain composition to the carefully engineered backup pad attachment mechanism, this disc delivers a sharp, forceful cutting action while simultaneously producing a consistent, uniform surface quality. This balance of performance characteristics makes it particularly well-suited for demanding industrial applications such as panel sanding and frame sanding operations where both efficiency and finish quality are essential requirements.

Our Hookit Attachment System

This disc is manufactured as part of 3M's comprehensive collection of hook-and-loop style Hookit discs, specifically engineered for work environments where traditional adhesive-backed abrasive products may experience contamination from accumulated dust, dirt, or airborne particulate matter. These Hookit discs feature a secure hook-and-loop fastening mechanism that attaches firmly to a compatible hook-and-loop backup pad (available separately) on random orbital sanders. A key advantage of this system is the ability to remove discs cleanly without residual adhesive, and the capability to reapply and reuse the same disc multiple times until the abrasive material is fully depleted.
