Scotch-Brite General Purpose Hand Pad 7447 combines flexibility with effective cutting action and precise hand control to accomplish tough cleaning jobs or produce fine finishing results, use after use. Very fine grade aluminum oxide abrasives cut fast and fine, leaving a smooth, finished surface. Suitable for use on a wide variety of materials and for many different tasks. The performance of Scotch-Brite General Purpose Hand Pad 7447 is comparable to steel wool grade 1. However, unlike steel wool, our Scotch-Brite pads won't shred during use, rust after use, or create fine metal splinters. The non-woven, open-web material resists loading and can be used dry, with water or solvents, and rinsed clean for reuse. This multipurpose 6 x 9" pad can be used by hand for precise control, with a hand pad block for uniform finishing, or on an in-line sander to cover large areas. Aluminum oxide is a popular choice among industrial professionals because of its cut-rate and long life. This mineral is a tough, durable abrasive that self-fractures to expose fresh cutting edges in use, whereas traditional abrasives, such as garnet, quickly wear down with use. Due to its high cut-rate, hardness, strength, and low heat retention, aluminum oxide mineral is widely used in grinding applications in addition to sanding and finishing use. Aluminum oxide is suitable on a wide variety of substrates in both woodworking and metalworking, including ferrous alloys. Our Scotch-Brite industrial abrasive products are a unique surface conditioning product with abrasives incorporated into non-woven nylon or other synthetic fibers. Combining abrasives into the fibers creates an abrasive system that delivers consistent results for the life of the product. The open-web material is load resistant and keeps the abrasive minerals cutting at high performance by limiting clogging of the fibers.
