The quick-release nut allows you to change cutting, grinding and sanding discs up to a diameter of 150 mm quickly and without tools. It has a folding lever that locks securely in the 0 and 90° position. A manual turning movement to the left or right loosens and secures the flange nut quickly and easily. If necessary, this can also be done with a flange spanner. Corresponding holders are also available. Thanks to the M-14 thread, the quick-release nut is compatible with standard angle grinders.
