The Cameo Gold non-diamond grinding discs can be used with diamond abrasives during the rough and intermediate steps. These discs feature a patented honeycomb cell structure that minimizes time and surface area contact with the sample, allowing for better circulation of diamond suspension. They are recommended for polishing soft and non-ferrous materials using diamond abrasives between 6 to 15 microns. It comes with adhesive or magnetic backing options for added convenience.
