PRODUCT FAQ

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

The 60+ F-weight grit provides an aggressive cut that's ideal for fast stock removal and initial sanding applications. It's designed to work efficiently on a variety of substrates while maintaining excellent durability.
Will this disc work with my standard sanding pad?

Yes! The Hookit attachment system is the standard quick-change interface, so this 5-inch disc will work with any compatible Hookit backing pad. It's designed for convenience and easy disc changes.
How many discs come in each order?

Each carton contains 50 discs, and we sell them in cases of 250 discs total—that's 5 cartons per case. This packaging makes it easy to stock up for your operation.
What makes Cubitron II better than regular sanding discs?

Cubitron II features a revolutionary grain technology that fractures as it wears, continuously exposing fresh, sharp surfaces. This means you get faster cutting, longer life, and cooler operation compared to traditional abrasives—ultimately saving you time and money.

```html Cuts Fast Without Loading

The 3M Cubitron II Hookit Disc 950U incorporates 3M Precision-Shaped Grain technology, an innovative abrasive solution that undergoes continuous micro-fracturing during use. This self-sharpening mechanism generates fresh cutting edges throughout the product's lifespan, enabling the disc to maintain exceptionally rapid material removal rates. The sustained sharpness of the grain also minimizes friction and heat generation on the workpiece substrate, which is particularly beneficial when processing heat-sensitive materials like aluminum. The grains are strategically positioned in an open-coat configuration, which significantly reduces the accumulation of abraded material and swarf on the disc surface—a critical advantage when working with aluminum and other materials prone to clogging. The convergence of these design features produces an abrasive solution that delivers superior cutting speed and extended service life compared to conventional alternatives.

Aggressive Cut, Smooth Finish

The 3M Cubitron II Hookit Disc 950U represents a comprehensive engineering achievement that balances cutting aggression with surface quality refinement. From the precisely engineered abrasive grain structure to the scientifically designed backup pad attachment mechanism, every component works synergistically to deliver a sharp, forceful cutting action while simultaneously producing uniform and consistent surface finishes. This makes the disc particularly well-suited for demanding panel sanding and frame sanding operations where both material removal efficiency and aesthetic surface quality are essential requirements.

Hookit Attachment System

This disc is part of 3M's comprehensive Hookit line, which features a hook-and-loop mechanical fastening system designed specifically for work environments where traditional pressure-sensitive adhesive backings may be compromised by dust accumulation, debris, or airborne particles. The Hookit discs securely fasten to a compatible hook-and-loop backup pad (available as a separate purchase) mounted on random orbital sanders, and offer the distinct advantages of convenient attachment, straightforward removal, and the ability to be repositioned and reused multiple times throughout the abrasive's functional lifespan.
