Collection: Gesswein® EDM Stones

EDM Stones are specially designed to remove the tough, hard scale left by the Electric Discharge Machining (EDM) process faster than any other polishing stone in our lineup.
- Made with premium white aluminum oxide that fractures into sharp, fresh edges for extended abrasive life
- Cuts fast, resists loading, and breaks down slowly for aggressive yet controlled polishing
- Ideal for medium to hard tool steels up to Rockwell C 62
- Special clay bond maintains stone shape, making it perfect for detailed work and sharp corners
