These 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.
The 341D features 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.
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 the 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.
