3M Stikit Cloth Disc 726A features ceramic 3M Precision-Shaped Grain, a revolutionary advancement in abrasive technology. The triangular shaped ceramic mineral is designed to slice through the substrate, rather than gouging or “plowing” like conventional abrasives. The J-weight cloth backing balances durability with flexibility for a wide range of substrates.These discs are ideal for a broad range of applications focused primarily on stock removal, and are particularly effective in tough sanding applications. The cloth backing offers additional durability and edge retention. For best results, pair with 3M Elite Random Orbital Sanders. We offer a complete line of 3M Stikit discs, which come ready to use with a pressure sensitive adhesive coating on the backside so that attaching them to your 3M Stikit 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.
