The Alpha® gear-action sander/polishers offer the best of a single-action sander and a dual-action sander. These tools have a very high torque that is best suited for sanding and polishing applications. The low speed prevents the risk of burning on paint or the surface as well as prevents the surface from becoming "hairy" when used on FRP. The high torque makes the sanding action very aggressive so that it is best suited to strip rust, paint and other coating materials without creating distortion. In addition, strong torque also helps with the chemical applications when used with foam or a wool bonnet for the final polishing process of paint. The Alpha® gear-action sanders will not leave a swirl mark because of the orbital action typically caused by a rotary polisher that offers a lot of torque. The units have a dust port available to hook-up to a dust hose for a virtually dust-free central vacuum sanding application. Combine this with the Alpha® HEPA vacuum for great dust control and a cleaner environment!
