5" Foam riser pad to allow further flexbility & even wear of edge polishing hand pads.  No more torn resin pad edges, these foam risers allow even diamond edge pad wear and further protect the 5" pad holder from wear.  A true cost savings not only of your expensive edge pad holders but savings hundreds on edge pads that get worn, unusable edges.  TECH NOTE; DUE TO THE ADDED THICKNESS OF YOUR EDGE POLISHING UNIT- YOU MAY NEED AN ADDITIONAL SKIRT ADDED TO YOUR HAND GRINDER DUST SHROUD.  We provide custom shrouds in the hand tool section.
