Product information "Grinding and polishing stone, joke FD, bench stone"

These ceramic oxide stones consist of mixed crystals of outstanding hardness. The main component is aluminium oxide. This crystal occurs naturally as ruby, hence the name “ruby stones” or “degussit”.

The stones are free of bonding agents, absolutely dimensionally stable and low-wear. Ideal for manual use and in ultrasonic polishing systems.

Tip: well suited for carbide metal processing and very fine finishing after grinding.
