Can’t remove cutting disc from Angle Grinder

Typically, a cutting disc can be hard to remove because the locking nut was overtightened when fitted to the grinder. A disc will tighten under loading, so excessive tightening will cause issues with removal, that may require a pin spanner or wrench to remove it.
