Features Outlasting sandpaper by up to 10 times, aluminium oxide is the abrasive paper of choice used by trade professionals and ProFlex takes it to the next level. It replaces the standard backing paper with an ultra-flexible, crack-resistant cotton cloth, giving outstanding performance with curved and profiled surfaces by moulding effortlessly to match their shape for fast, efficient sanding. Featuring durable aluminium oxide grains that have a self-sharpening action and clog less, ProFlex is ideal both for hand sanding – with or without a sanding block. These half size sheets are ideal for smaller jobs and are available in Fine, Medium and Coarse grits and an Assorted pack.
