PRODUCT FAQ

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

The 950U comes in 80+ F-weight, which is an excellent medium grit perfect for general purpose sanding, material removal, and finishing on wood, composite, and painted surfaces. It's versatile enough to tackle both aggressive stock removal and intermediate finishing work.
Does this disc require a hole pattern, and what size is it?

Great question! The 950U is a no-hole disc, which means it's designed for hook-and-loop (Hookit) attachment directly to compatible 6-inch sanders without needing a vacuum hole pattern. This gives you maximum sanding surface area.
How many discs come in a standard order, and what's the packaging like?

You'll receive 50 discs per carton, and we package them in cases of 250 each (that's 5 cartons per case). This bulk packaging is perfect for keeping your shop well-stocked and ready for production work.
Why would I choose Cubitron II over standard abrasives?

Cubitron II features our advanced grain technology that stays sharper longer, delivering faster cutting and longer disc life. You'll see reduced sanding time, less dust, and better finish quality—which really adds up when you're running high-volume operations.

Cuts Fast Without Loading

The 3M Cubitron II Hookit Disc 950U is engineered with 3M Precision-Shaped Grain technology, an innovative advancement that strategically fractures throughout the sanding process to consistently expose fresh, sharp cutting surfaces. This dynamic grain behavior enables the disc to maintain a remarkably high cutting velocity across its entire operational lifespan while simultaneously reducing the risk of substrate thermal damage. The grains are arranged in an open-coat configuration that effectively minimizes abrasive particle accumulation—a critical advantage particularly when working with softer metals such as aluminum. The synergistic combination of these design elements produces a sanding disc that demonstrates superior cutting speed and extended durability compared to conventional abrasive alternatives.

Aggressive Cut, Smooth Finish

The 3M Cubitron II Hookit Disc 950U represents a harmonious integration of scientific innovation, structural integrity, and refined finishing capability. From the carefully engineered grain composition to the precision-engineered backup disc pad attachment system, this product delivers a sharp and forceful cutting action while producing a consistent and uniform surface finish. These characteristics make it particularly well-suited for demanding panel sanding and frame sanding applications where both efficiency and quality results are essential.

Hookit Attachment System

This disc is part of 3M's comprehensive selection of hook-and-loop style Hookit discs, specifically designed for work environments where conventional adhesive-backed discs are susceptible to contamination from dust accumulation, surface dirt, or airborne particles. Hookit sanding discs feature a dependable and secure attachment mechanism that connects to a compatible hook-and-loop backup disc pad (available separately) on random orbital sanders. The discs detach cleanly without residue and can be repositioned and reused multiple times throughout their abrasive lifespan, providing excellent value and operational flexibility.
