3M™ Cubitron™ II Stikit™ Film Discs feature 3M™ proprietary Precision Shaped Ceramic Grain, a revolutionary advancement in abrasive technology. The sharp, triangular shaped ceramic mineral is designed to slice through the substrate, rather than gouging or “plowing” like conventional abrasives, resulting in a disc that cuts up to 2x as fast and lasts up to 6x as long as conventional abrasives.

These discs are ideal for a broad range of applications focused primarily on stock removal, and are effective on a wide variety of substrates, including metals, composites, gelcoat, and wood. The 3 mil film backing offers greater tear resistance than paper discs for additional durability and edge retention.

The 3M™ Stikit™ system eliminates the time-consuming task of applying adhesive to the disc backing. These high-quality, coated abrasive products come ready to use with a pressure sensitive adhesive coating on the backside so that attaching them to your disc pad is as simple as pressing on a sticker. And because the adhesive is pressure sensitive, the disc can be peeled off of the disc pad just as easily, leaving a clean surface for your next disc. A Stikit™ disc must be pressed onto a Stikit™ backup pad (also called a disc pad and sold separately) that is attached to a disc sander, random orbital sander, or stationary disc sander.

What makes 3M ™ Cubitrom II ™ abrasives so special??

The secret behind the revolutionary performance of Cubitron™ II abrasives lies in their Precision-Shaped Grain (PSG) Technology — the result of decades of technological advances in ceramic abrasive and microreplication technologies. These precision-shaped grains are uniformly sized triangular structures that are super-sharp and evenly distributed onto the backing, allowing them to slice through material like a knife through butter rather than gouging or plowing as other abrasives.  These triangular shaped grains are electrostatically oriented on the backing with their cutting edges facing the work surface for the most efficient cut and even wear. As the triangular shaped grain wears, the cutting edge continuously fractures to form new, sharp points and edges that continue to slice through material, wear evenly, provide super-long life and produce a consistent finish. This allows 3M Cubitron II ™ belts and discs to run cooler and keep on working—long after conventional abrasives have dulled, shelled, glazed over and been thrown out. Conventional abrasives tend to be irregular and blocky in shape. So, instead of a clean, machining action, conventional grain tends to “plow” through material, causing heat to build up both in the workpiece and the abrasive — resulting in a slower cut, shorter abrasive life and a lower quality finish. Cubitron II ™ abrasive discs are available resin-bonded to a stiff, super-tough, tear-resistant film backing offering greater tear resistance than paper discs providing greater durability and edge retention. Cubitron II ™ discs and belts lasts significantly longer than conventional abrasive allowing more parts to be sanded per disc with fewer disc changes.
