The T-REX velcro backed electroplated diamond sanding discs are often called diamond sand paper. They offer the most aggressive removal rate you can imagine - they are much faster than an impregnated grinding disc because they have 100% diamond exposure. These diamond polishing/sanding discs can be used wet or dry on a sander or grinder， and they operate well at any speed. The pads work on concrete， stone， tile， wood， swimming pool surfaces (the Only answer to quickly sanding PebbleTec)， metals， even glass.
