For rockhounds, jewelers, or anyone into lapidary work, this diamond flat lap disc is a game-changer. It’s a 6-inch diameter wheel with a 1/2-inch arbor hole, so it fits most angle grinders or faceting machines. The 400 grit is a nice middle ground – great for smoothing out scratches, shaping stones, or pre-polishing before you move to finer grits. It works on all sorts of materials: agate, jade, crystal, glass, ceramics, even marble or granite. The diamond surface is electroplated, so it stays sharp and wears slowly, giving you consistent results over many uses. The disc is super flat and parallel, which is key for precision faceting or getting an even polish. Whether you’re turning rough rocks into cabochons, shaping sea glass, or polishing tabletops, this lap disc handles it with ease. Just remember to use water or coolant while grinding to keep things cool and extend the disc’s life. A must-have for hobbyists and small workshop projects.
