Our discs feature a heavy, X-weight cloth backing with a resin bond that prolongs disc life in high heat and high pressure applications, and fast-cutting aluminum oxide grain offers fast continuous cut and long-life performance on many substrates. The 3M Stikit backing presses onto the backup pad easily and comes off easily, making grade changes quick and easy.
We chose aluminum oxide, which is a popular choice among industrial professionals because of its fast cut-rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges, whereas traditional natural abrasives dull more quickly. Due to its fast cut-rate, hardness, and strength, it is widely used in grinding applications in addition to sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys.
Our 3M Stikit discs come ready to use with a pressure sensitive adhesive coating on the backside so that attaching them to the disc pad is as simple as pressing on a sticker. The disc can be peeled off of the disc pad just as easily, leaving a clean surface for your next disc. Stikit disc rolls offer the convenience of tearing off a disc and eliminate the need for a liner. A Stikit disc should be used in conjunction with a 3M 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.
