8"x2" 220Grit Premium Sintered Diamond Grinding Wheels for Gemstone & Glass Shaping

Our Sintered Diamond Grinding Wheels are diamond grinding wheels, professionally engineered to provide maximum cutting performance and long-lasting durability. They are ideal for gemstone shaping, cabbing, and faceting pre-grinds, ensuring consistent material removal with precision for both professional and hobbyist lapidary artists.

Unlike plated or resin bond diamond grinding wheels, these wheels feature a 5mm deep metal-bonded and sintered diamond matrix, ensuring continuous exposure of fresh diamond layers. This design provides aggressive grinding power, consistent sharpness, and long-lasting performance for demanding lapidary applications.

These sintered diamond grinding wheelsare compatible with vertical cabbing machines and flat lap grinders, each equipped with a solid metal core for stability and vibration-free operation. Available in 6-inch and 8-inch diameters with grit options from 60 to 600, these diamond grinding wheels handle everything from coarse stock removal to fine pre-polishing. Equipped with a 1" arbor and bushings for 1/2", 5/8", and 3/4" shafts, these diamond grinding wheels provide versatile, reliable performance for professional lapidary artists, hobbyists, and high-volume workshops alike, making gemstone, glass , and ceramic processing efficient and precise.
