Diamond Flat Lap Disc, 8" x 1/2" Arbor 500 Grit, Diamond Coated Flat Lap Wheel for Gemstone Ceramics Stone Glass, Grinding Sanding Disc Lapping Polishing Disc

This product is a lapidary diamond disc that comes in a thin design. Although the product is inexpensive and boasts of fast shipping, it receives mixed reviews from customers who have purchased it in the past. On the positive side, some customers assert that the disc is well made and lacks any sharp edges, and that shipments arrived faster than advertised. However, some customers received the product with all three discs warped, which is a cause for concern because it makes them unsuitable for achieving the desired result. This prompted one user to vow never to order from the company again. For a first-time user, the thin design may be problematic, which suggests that using a master lap under it is necessary to ensure effectiveness.
