10” diameter diamond grinding disc with a magnetic rubber backing. It attaches to any steel diamond disc to give you an additional #800 (very fine) grit for grinding and smoothing imperfections or grinding marks. It leaves a very smooth surface. It is very easy to pop on and off your main disc. It cannot be used on a potter's wheel as a stand alone tool because there would be no way to attach it.

I purchased a great grinding disk for the cost ( I get several of these), and combined with great service in getting the product sent out quickly ... all make this a great place to find and order needed items for ceramic work. Highly recommended.
