From the Manufacturer The 3M™ Clean Sanding Disc 360L is constructed of fast-cutting aluminum oxide abrasive grain on a durable film backing and works well for fine sanding on plastics, gel coats, and polyurethane solid surface substrates where dust collection is preferred. The sturdy film backing provides the durability needed for a high-production environment, and its excellent resistance to edge tearing increases the life of the disc over discs with standard A-weight paper backings. At the same time, the film backing provides a close-tolerance, consistent finish, making it a good choice for applications such as spot repairs, sanding plastic parts, paint feathering on defects, or sanding automotive primer. Used with a vacuum system, the Clean Sanding multi-hole pattern provides excellent dust extraction and eliminates the need to line up dust-free holes. To further reduce loading on the disc, the disc has open coat construction without a load-resistant stearate coating. The convenient Hookit hook-and-loop attachment on the disc backing enables easy re-use so the disc can be used again and again for the life of the product. It attaches to a low-profile 3M™ Hookit™ Disc Pad (sold separately) on a random orbital sander. Clean Sanding Disc 360L comes in a range of grades for various applications from fine sanding to finishing. Sandpaper discs cut better and last longer when dust isn’t loading the cutting surface of the abrasives. Reducing dust is easier than ever with 3M™ Clean Sanding Discs. The Clean Sanding multi-hole pattern evacuates dust better than 5- or 6-hole products—significantly increasing cut-rate and disc life. When used with a 3M™ Clean Sanding Disc Pad, the disc holes do not require alignment with the pad holes, making switching the discs fast, easy, and convenient. An open coat means the abrasive grains have space between them so that sanding debris collects in the spaces rather than loading the cutting edge of the grains. Aluminum oxide 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 offers a complete line of hook-and-loop style Hookit discs for work spaces where adhesive backed discs may become contaminated by dust, dirt, or flying debris. They are often used in applications where a 3M™ Stikit™ disc may be too aggressive, as Hookit discs tend to leave finer finishes than adhesive backed discs. Hookit sanding discs conveniently and firmly attach to a hook-and-loop backup disc pad (sold separately) on a random orbital sander, can be removed cleanly and easily, and can be re-used again and again for the extent of the abrasive life.
