PRODUCT FAQ

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

The 40+ F-weight grit makes this disc ideal for aggressive material removal on a variety of surfaces including wood, composite materials, and painted surfaces. It's designed to cut faster and last longer than conventional abrasives, so you get more efficiency on your projects.
Is the "No Hole" feature a problem for dust collection on my orbital sander?

Not at all! The "No Hole" design actually works great with sanders that have dust collection systems built into the pad itself. The dust collection slot on your sander will pull dust effectively across the entire disc surface, giving you excellent visibility and a cleaner work area.
How many discs will I receive, and how should I store them?

You'll receive 250 discs total per case, which comes organized as 50 discs per carton for convenient handling and storage. We recommend keeping them in a cool, dry place in their original packaging to maintain their adhesive quality and ensure they're ready to perform when you need them.

High-Speed Cutting Without Loading

The 3M Cubitron II Hookit Disc 950U is engineered with 3M Precision-Shaped Grain technology, a cutting-edge advancement that strategically fractures during use to consistently expose fresh, sharp cutting edges. This innovative grain structure enables the disc to maintain an impressively elevated cutting rate throughout its entire operational lifespan, while simultaneously minimizing the risk of substrate overheating—a critical advantage in precision sanding applications. The grains are strategically positioned in an open-coat configuration across the disc surface, which effectively mitigates abrasive particle loading, an especially important consideration when working with softer materials such as aluminum. The synergistic combination of these design features produces an abrasive solution that delivers superior cutting performance and extended service life compared to conventional alternatives.

Aggressive Performance with Refined Results

The 3M Cubitron II Hookit Disc 950U represents a comprehensive engineering approach that integrates scientific precision, structural durability, and finishing quality at every level—from the grain composition to the backup pad attachment mechanism. This holistic design philosophy results in a disc capable of delivering sharp, forceful cutting action while simultaneously producing a consistent, refined surface finish. The disc excels in demanding industrial applications such as panel sanding and frame sanding, where both cutting efficiency and aesthetic quality are essential requirements.

Hookit Attachment System

This disc is part of 3M's comprehensive Hookit disc lineup, specifically designed for work environments where traditional adhesive-backed discs may be compromised by accumulating dust, debris, or airborne particles. The Hookit discs feature a hook-and-loop attachment mechanism that securely fastens to a complementary hook-and-loop backup pad (available separately) mounted on random orbital sanders. This system allows for tool-free removal and reinstallation, enables straightforward cleaning between applications, and permits multiple reuse cycles throughout the abrasive's serviceable lifespan.
