3M™ Cubitron™ II Hookit™ Disc 950U, 120+ F-weight, 6 in, No Hole, Die 600Z, 50/Carton, 250 ea/Case

The 3M Cubitron II Hookit Disc 950U incorporates 3M's advanced Precision-Shaped Grain technology, a cutting-edge innovation engineered to continuously break down and fragment during the sanding process. This self-renewing fracturing mechanism consistently exposes fresh, sharp cutting edges throughout the entire lifespan of the disc. The result is a sustained and impressively high cutting rate that remains consistent from the first use through the disc's final applications. Additionally, this advanced grain structure works to minimize heat generation on the substrate being sanded, which is particularly beneficial when working with heat-sensitive materials like aluminum. The grains are strategically distributed across the disc's surface in an open-coat configuration specifically designed to prevent abrasive particle accumulation—a common challenge that typically occurs during aluminum sanding operations. When these technological advantages are combined, the result is a superior abrasive disc that delivers faster material removal while simultaneously extending the product's operational lifespan compared to conventional sanding discs.

The 3M Cubitron II Hookit Disc 950U demonstrates an exceptional balance between cutting aggression and finish quality. Through a carefully engineered combination of advanced grain technology, material composition, and a precision-engineered backup pad attachment system, this disc produces a forceful cutting action while maintaining a smooth and consistent surface finish. This dual capability makes it exceptionally well-suited for demanding industrial applications including panel sanding and frame sanding operations where both productivity and quality are essential requirements.

This disc is part of 3M's comprehensive Hookit disc collection, which was specifically developed for work environments where traditional adhesive-backed discs are prone to contamination from airborne dust, dirt particles, or debris. The hook-and-loop design allows for quick and secure attachment to compatible backup pads mounted on random orbital sanders, while also enabling simple removal without residue or damage. A significant advantage of this system is the ability to remove and reattach the same disc multiple times throughout its useful life, maximizing material efficiency and reducing waste.
