Diamond grinding wheel on shaft

The diamond grinding wheel is provided with a fixed shaft with a diameter of 2.35 mm. The discs have a diameter of 16 mm and 24 mm.
 
 
This diamond discs are usable in conjunction with the various electric multi tools.
 
Diamond Grinding Discs are suitable for the machining of:
carbide
glass, ceramics (also Eng.-ceramics) and porcelain
wear resistant layers
ferrite, silicon
graphite, carbon brushes
thermosets, glass fiber reinforced plastics
natural and artificial stone
refractory
 
For machining steel, the diamond disc should not be used, because a chemical reaction between the iron (Fe) in the steel and carbon (C) in the diamond cause a very rapid wear of the diamond tool.
