What sets the Proxxon Abrasive Sphere apart

The set of three stones offers enough material to complete a full grinding session without interruption, making it suitable for both occasional hobby work and regular workshop use.
Ideal for...
Model makers, metalworkers, and hobbyists who need precise material removal on curved or spherical surfaces. The 9 mm size is particularly suited for detailed finishing work on small components where larger grinding tools would be impractical.
