Essential for jewelry making, these separating discs are specifically designed for cutting chrome and non-precious metal casting sprues, prongs, shanks, and more. Made with pure bonded silicon carbide abrasive in a special binder, they deliver fast, cool cutting and clean finishing on materials such as porcelain, acrylic, gold, and various alloys. The discs feature a pinhole mount, making them compatible with flex shafts and standard mandrels—ideal for precision work in jewelry production.
