Our Sintered Diamond Grinding Wheels are engineered for maximum durability and consistent cutting performance, making them perfect for gemstone shaping, cabbing, faceting pre-grinds, and heavy material removal on quartz, agate, sapphire, ruby, glass, and ceramics . Unlike plated or resin bond wheels, these wheels feature a 5mm deep metal -bonded and sintered diamond matrix, ensuring continuous exposure of fresh diamond layers for long-lasting sharpness and aggressive grinding.Designed for vertical cabbing machines and flat lap grinders, each wheel has a solid metal core for stability, precision, and smooth, vibration-free operation, with factory dynamic balancing for quiet, concentric grinding. Available in 6-inch and 8-inch diameters with grit options from 60 to 600, these 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, this sintered diamond grinding wheel is versatile, long-lasting, and essential for professional lapidary artists and high-volume workshops.Whether shaping gemstones, polishing glass, or preparing materials for jewelry making, our sintered diamond grinding wheels provide the precision, durability, and efficiency you need for high-quality results.
