The 8″ (20cm) Diamond Grinding Disc from DiamondCore® Tools is the perfect grind disc for pottery pieces. These diamond sanding discs are faster than sandpaper or silicon carbide with much less fatigue. Choose from 60, 120 or 240 grit sizes depending on your diamond sanding disc needs.

Diamond Sanding Discs Installation: Select a smooth, clean, flat waterproof bat to dedicate. Draw centring rings on the bat. Peel and remove the red film from the back of the grinding disc. Place the grinding disc in the centre of the bat, and adhesive side down, taking care to keep it in the centre. Press down and keep weight of 25 pounds on it overnight while flat for maximum bond.

    I have not use this yet, only the strips of Daimond sanding “paper”. That convinced me to buy this. This is a great time saver.
