These qualities cut down set-up times and provide for more effective abrasive performance. The three hardnesses of the backing pad combined with the extensive selection of sizes allow for a wide variety of applications. The backing pads with QMC locking always perform with perfect safety and dependability thanks to their ease of use. Since they also offer exceptionally smooth operation, the backing pads also help users work over a long period without fatiguing. Meanwhile, they are also a major factor in achieving uniform sanding results. The permissible motor speed is 20,000 or 30,000 revolutions per minute - depending on the diameter of the backing pad. The larger the diameter, the lower the speed that needs to be selected.
