The Walter ALU Grinding Wheel (08L705)<\/strong> is a specialized abrasive tool engineered specifically for the unique challenges of working with aluminum and other soft, non-ferrous metals. In industrial fabrication, grinding aluminum is notoriously difficult because the material has a low melting point and tends to “load” or clog the surface of standard grinding wheels. Once a wheel is clogged, it stops cutting, generates excessive heat, and becomes dangerous to use. Walter Surface Technologies has solved this problem with their proprietary ALU formulation.<\/p>\n This 7-inch wheel features a coarse A24 grit<\/strong> and a soft bond that allows the abrasive grains to break away at the optimal rate, exposing fresh, sharp grain constantly. This self-sharpening action prevents the aluminum from adhering to the wheel face. As a result, operators experience a continuous, aggressive removal rate without having to stop and dress the wheel or apply friction-reducing lubricants like wax or paraffin. This not only saves time but also keeps the workpiece cleaner, reducing the need for post-process cleaning before welding or finishing.<\/p>\n The 08L705 comes equipped with a 5\/8-11 threaded arbor<\/strong>, allowing for quick “spin-on” mounting to standard 7-inch angle grinders. This hub design increases safety and reduces vibration compared to standard non-threaded wheels. With a maximum rating of 8,600 RPM<\/strong>, this Type 27 depressed center wheel is ideal for heavy-duty stock removal, weld blending, and edge chamfering on aluminum structures, trailers, and marine components.<\/p>\nKey Benefits for Fabricators<\/h3>\n
