PRODUCT FAQ

What grit is the 3M Xtract Cubitron II Paper Disc 950U, and what does the 40+ F-weight mean?

The disc is 40+ grit with an F-weight paper backing. The F-weight indicates a heavier, more durable paper backing that resists tearing and provides excellent durability during sanding operations, making it ideal for tougher applications.
What size is this disc, and how many holes does it have?

This is a 5-inch disc with a multi-hole pattern. The multi-hole design works with vacuum systems to provide consistent dust collection and better workpiece visibility during sanding.
How many discs come in each package, and what's included in a full case?

Each carton contains 50 discs, and a full case includes 250 discs total, which means you get 5 cartons per case for convenient ordering and storage.
What makes Cubitron II technology better than standard abrasives?

Cubitron II features advanced grain technology that fractures during use to continuously expose sharp cutting edges, delivering faster sanding speeds, longer life, and better consistency compared to conventional abrasives—which means more efficiency and better value for your operation.

Fast Cutting with Minimal Loading

The 3M Cubitron II Hookit Disc 950U incorporates 3M's PrecisionShaped Grain technology, which has been engineered to continuously fracture during use, exposing sharp, fresh cutting points that sustain high cut rates throughout the disc's operational lifespan. This advanced grain fracturing mechanism significantly reduces heat generation on the workpiece surface, a critical consideration when working with heat-sensitive materials. The disc features a very open-coat construction that actively resists loading—the buildup of sanding debris on the abrasive surface—making it particularly effective for aluminum sanding applications where loading is a common challenge. This combination of design features ensures fast, consistent sanding performance while extending the overall life of the disc.

Aggressive Cutting Performance with Superior Surface Finish

Engineered to balance both cutting power and operational efficiency, the 950U disc delivers aggressive material removal while simultaneously producing a clean, uniform finish across the workpiece. This makes it particularly well-suited for panel and frame sanding applications in automotive and industrial refinishing work. The disc maintains consistent cutting performance and finish quality from the initial cut through the final finishing pass, eliminating the typical performance degradation seen with conventional abrasive discs.

Integrated Dust Extraction System

This product is engineered as part of the 3M Xtract Clean Sanding System, which prioritizes optimal dust removal and workplace air quality. The disc features a proprietary multi-hole extraction pattern that has been proven to outperform conventional 5- or 6-hole designs in dust collection efficiency. Additionally, the innovative hole pattern design enables rapid disc changes without requiring manual alignment with the backup pad, streamlining the workflow. For maximum dust extraction effectiveness, this disc should be paired with a 3M Xtract Back-up pad and 3M Xtract Random Orbital Sander equipped with vacuum collection (sold separately).

Hookit Attachment System

Ideal for environments where adhesive-backed discs are prone to contamination from dust and debris
Less aggressive than 3M Stikit adhesive-backed discs, making them suitable for achieving refined surface finishes
Attaches securely to hook-and-loop backup pads for reliable performance
Can be removed cleanly from the backup pad and reused multiple times throughout the abrasive's effective lifespan
Provides enhanced cost-effectiveness and operational convenience compared to single-use alternatives
