The new wavy edge design of these discs overhangs the holder and arches around the edge to help prevent “dig ins” caused by the edge of the disk contacting the surface of the wood. Made of Hi-Per Gold sandpaper which uses special lubricants on the surface of the discs to reduce loading and resin clogging, and incorporates an extremely flexible backing which smoothly conforms to curves. New Wave hook and loop backed disks may be used on standard foam sanding pads, but for best results the interface backing pads should be used between the foam pad and the disks.

Features:
• Oversized disc with wave edges made from aluminum oxide
• "C" weight paper and hook and loop backing
• Used for finishing inside radius corners, coves and molds
• Used with dual action finishing sanders
• Wave edge extends over the edge of the backup pad
