Change a grinding, cutting, or flap disc by hand — no pin spanner, no downtime. The Magic Flange Nut replaces your grinder's stock inner flange (install once); to swap a disc you just twist backward and its inclined surface + MBR rubber release the clamp. Fits any US-standard 5/8"-11 grinder.
As the disc spins, rotational force drives the OEM lock nut tighter than you ever set it — the self-tightening effect. Backing it off then takes a dedicated pin spanner: the consumable every shop loses and rebuys by the handful. No spanner on hand means the disc change is blocked and the job stops.
Replaces your grinder's stock inner flange. Install once — keep using your grinder's original lock nut. To change discs, twist backward by hand: the inclined surface and MBR rubber release the clamping pressure. No pin spanner. Ever.
A one-time swap, then it stays on the grinder. It works with your grinder's original lock nut — nothing extra to carry or lose.
Built for the US-standard 5/8"-11 spindle used across DeWalt, Milwaukee, Makita, Bosch and more — for grinding, cutting, and flap discs and wire wheels in 4½", 5", 7", and 9".
