PRODUCT FAQ

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

The 120+ grit means this disc is designed for medium-aggressive material removal. It's ideal for initial sanding and shaping tasks on a variety of surfaces.
What does "F-weight" mean on this product?

F-weight refers to the backing material thickness and flexibility. It's a flexible backing that works well with orbital sanders and provides good conformability to curved surfaces.
Why would I choose the 5-inch disc size?

The 5-inch diameter is a versatile standard size that works with most random orbital sanders. It's perfect for general purpose sanding on panels, trim, and other moderate-sized work areas.
What's the difference between the "No Hole" version and other versions?

The No Hole configuration means there's no dust collection hole in the center of the disc. This is ideal for applications where you don't need or want dust extraction, or for sanders that don't have dust collection capability.
How many discs come in each carton and case?

Each carton contains 50 discs, and each case contains 250 discs total—that's five cartons per case, giving you excellent value and bulk availability for ongoing job site needs.

Fast Cutting Without Clogging

The 3M Cubitron II Hookit Disc 950U incorporates 3M's Precision-Shaped Grain technology, an innovative advancement designed to progressively break down during use and expose continuously refreshed sharp cutting surfaces. This self-fracturing grain structure enables the disc to maintain a remarkably elevated cutting speed across its entire operational lifespan while simultaneously minimizing heat generation on the workpiece surface. The grains are strategically arranged in an open-coat configuration, which significantly reduces the accumulation of abraded material on the disc surface—a critical advantage when working with aluminum and other soft metals. The combination of these engineering features results in a sanding disc that delivers superior cutting performance and extended service life compared to conventional alternatives.

Vigorous Cutting Action with Refined Results

The 3M Cubitron II Hookit Disc 950U demonstrates the company's commitment to integrating advanced materials science, structural durability, and surface refinement throughout every component—from the engineered grain structure to the specialized backup pad attachment system. This comprehensive design approach produces a sanding disc capable of executing an intensive, aggressive cutting action that consistently yields smooth, even surface finishes. The disc proves particularly effective in demanding applications such as panel sanding and frame sanding, where achieving both rapid material removal and uniform surface quality is essential.

Hookit Attachment System

This disc is manufactured as part of 3M's comprehensive selection of hook-and-loop attachment sanding discs, designed specifically for work environments where traditional adhesive-backed abrasives may be compromised by accumulating dust, debris, or airborne particles. Hookit discs feature a secure mechanical connection to a matching hook-and-loop backup pad (available separately) on random orbital sanders, allowing for quick removal without residue, and offering the capability to be repositioned and utilized repeatedly throughout their abrasive lifespan.
