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 Innerface Backing Pads listed below should be used between the foam pad and the disks.
New Wave Bowl Sanding Kit contains one hook and loop sanding pad (1/4" shank), one hard and one soft innerface pad, and 5 each 80, 120, 150, 180, and 220 grit sanding pads.
Innerface Backing Pads are used between any standard hook and loop foam holder and the New Wave sanding discs. Available in soft and hard, soft for finer sanding and better conformation to curves, hard for heavy sanding or sanding up to beads and corners to prevent loosing their sharp definition. Note: Different grits of sandpaper may be kept on multiple backing pads so the sandpaper is not lost or damaged while changing grits.
