Mount these Cushion Pads onto the 3 inch Backpads for a smoother grind & a refined polish. Recommended for fine grade abrasives such as 220 grit and finer. Their flexibility helps sand and polish contours of rounded and domed workpieces and gives them a shock-absorption effect as well.
Simply stick them onto the Backpad before applying an Abrasive. They come in 3 flexibility options: Bumpon™, Medium-Flex and Soft-Flex.
