PRODUCT FAQ

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

The 150+ F-weight designation means this disc is designed for aggressive material removal on a variety of surfaces including metal, composite, and painted substrates. It's ideal when you need faster cutting and longer life compared to conventional abrasives.
Will this disc work with my random orbital sander, and what size is it?

Yes! The 5-inch size with Hookit attachment is compatible with most standard random orbital sanders and finishing sanders that accept that diameter. The Hookit backing makes it quick and easy to load and change out between jobs.
How many discs do I get, and what's the advantage of buying a full case?

You get 50 discs per carton, with 5 cartons in a case for a total of 250 discs. Buying the full case gives you excellent value and ensures you always have plenty of stock on hand, which means less downtime waiting for reorders and better cost per disc.

Cuts Fast Without Loading

The 3M Cubitron II Hookit Disc 950U is engineered with 3M's advanced Precision-Shaped Grain technology, a cutting-edge innovation designed to systematically fracture during use. As these grains break down progressively, they expose fresh, sharp surfaces that maintain optimal cutting efficiency throughout the product's operational lifespan. This continuous rejuvenation of cutting edges enables the disc to sustain impressively high material removal rates while simultaneously minimizing heat buildup in the workpiece, thereby reducing the risk of substrate damage or discoloration.

The abrasive grains are strategically arranged in an open-coat configuration across the disc surface, a design that significantly reduces the accumulation of abraded material and metallic particles on the working surface. This open structure proves particularly advantageous when working with aluminum and other soft metals that are prone to clogging conventional abrasive surfaces. The synergistic combination of these design elements results in a sanding disc that delivers superior cutting performance and extended product longevity compared to conventional alternatives in the marketplace.

Aggressive Cut, Smooth Finish

The 3M Cubitron II Hookit Disc 950U represents an integration of technological innovation, material durability, and precision engineering across every component, from the grain structure itself to the backing pad assembly. This comprehensive design philosophy produces a sanding disc capable of delivering powerful, efficient material removal while simultaneously producing remarkably consistent and uniform surface finishes. The disc excels in demanding applications such as panel sanding and frame sanding, where both efficiency and quality are critical requirements.

Our Hookit Attachment System

This disc is part of 3M's comprehensive selection of hook-and-loop style Hookit abrasive discs, specifically developed for work environments where traditional adhesive-backed products are vulnerable to contamination from dust, dirt, or airborne particles. The Hookit attachment system enables quick, secure fastening to compatible hook-and-loop backup pads (available as separate purchases) on random orbital sanders. The discs can be effortlessly removed without residue or damage, and offer the flexibility to be reused multiple times until the abrasive material is fully exhausted.
