50mm Fine Grit Flat Surface Grinding Wheel Bur

Diamond Drill Bits are precision tools for fine detailing and material processing. Discover the versatility of diamond drill bits, designed with durable diamond grit for aggressive cutting, precise shaping, and long-lasting performance. Available in multiple grits—coarse (40,60,80,120) for rapid material removal, and fine(240,600,1200) for detailed engraving and polishing. These tools suit lapidary artists, jewelers, sculptors, and precision craftsmen. Ideal for ultra-hard materials like wood, glass, ceramics, jade, hardened steel, and semi-precious stones, these diamond drill bits excel in both rough shaping and fine detailing. Coarse grits remove excess material quickly, while fine grits refine engravings, touch up surfaces, and deliver flawless finishes. Electroplated diamond tools further enhance performance on gemstones, ceramics, and metals. The shaft have 3mm,6mm and 12mm
