Tackling a stone polishing project? This is a 5-inch (125mm) diamond polishing pad with a 2000 grit. It's designed for wet polishing, which means you use it with water to keep dust down and get a better finish. The 2000 grit is a fine grit used for the final polishing stages – it's what gives granite, marble, engineered stone, or concrete that super smooth, high-gloss, mirror-like shine after you've done the coarser grinding. The diamonds are bonded with a resin material, which makes for a smooth polishing action. They're known for having a strong grinding force, working fast, and not leaving scratches or discoloration on the stone when used correctly. They fit standard 5-inch rotary grinders or polishing machines (like model 150 or 180 grinders). Remember, you usually need a set of pads starting from a low grit (like 50) and working your way up to a high grit (like 3000) for a professional result. This single 2000 grit pad is perfect if you just need to replace one or complete your set for that final buff.
