Wool, felt or plain rubber wheels test delicate materials or abrasiveness of materials such as dental powders.
Wheels featuring abrasive particles in a resilient matrix of rubber or a hard matrix of vitrified clay are suitable for stiffer materials.
- Calibrase®: resilient abrasive wheel – rubber and aluminium oxide
- Calibrade®: a non-resilient abrasive wheel – vitrified clay and silicon carbide
- Plain Rubber: contains no abrasive particles unless used with sandpaper strips
- Tungsten Carbide: severe cutting and tearing action with helical teeth for use on resilient materials such as rubber, leather and floor coverings
