Very fine grade aluminum oxide abrasives cut quickly and well, leaving a smooth and finished surface. Pad can be used for a wide variety of materials such as wood, metal, plastic, ceramic, porcelain, glass, rubber or composites and for many different activities, with comparable performance to grade 0 steel wool. However, unlike steel wool, Scotch-Brite 7447 PRO pads do not rust after use or create thin metal chips. The unwoven open texture material resists load and can be used dry, with water or with some solvents. This 6 x 9 inch multipurpose pad can be used by hand for precise control, with a manual bearing block for a uniform finish, or with an inline sanding machine for large areas. This ruby-colored manual pad contains abrasive in aluminum oxide. Aluminium oxide is a common choice among industry professionals thanks to cutting speed and long life. This mineral is a durable and durable abrasive that fractures to expose new sharp edges during use, while traditional abrasives, such as garnet, smooth themselves quickly. Thanks to its high cutting speed, hardness, strength and low heat retention, the aluminum oxide mineral is highly used for sanding and finishing applications. Aluminium oxide is suitable for a wide variety of substrates both in wood and metal processing, including ferrous alloys. The pad is perforated in the center, allowing easy hand laceration to reduce waste.
