Supanut holds the disks just like normal but you can loosen this nut with your fingers and it will never over tighten. Imagine that, go from cutting to grinding in an instant without tipping your whole tool box on the ground looking for the spanner.
Supanut is suitable for most angle grinders. You can use the Supanut when changing cutting & grinding discs, diamond blades, flap wheels and other thin walled accessories
