PCD Delosh heavy material removal diamonds.  These diamonds are used to remove thick epoxy and floor glues from concrete floors prior to further diamond grinding.  Long life, high quality pcd's tear into the floor coatings.  TECH NOTE:  Do not overgrind the concrete with pcd's as it will highly destroy the concrete surface and make further concrete polishing difficult to remove scratches.  PCD's should be able to be run very quickly across the layers, only removing 80% of the surface stock allowing the following Delosh 20/25 grit diamonds to finish preparing the concrete without 'gumming' or smearing the glues/epoxy.

 Redilock adapter or machine plates required.
