I probably mentioned it around here before but I have a specialty wrench bent for removing the transmision of a 1970 to 1974 Opel Manta.

If anyone wants to borrow it let me know!

I once used my 4" grinder to simply cut the nut from a 7" grinder, cutting it clean through right next to the axle.
The disc had grabbed into something and tightened the nut to where nothing with get it to budge and the holes started to develop some slack.

I'm a millwright by trade. I have used 100's and 100's of grinding discs, zip cuts and sanding pads.

Often on a job site the supplied wrench is not available. Around us most of us carry channellock pliers. Those are used often. It's controlled and much safer then my favourite way when there is no wrench around.

With the grinder in your right hand with the disc facing left. Push the button in to lock the disc and prevent it from spinning, with great haste drive the grinder (disc) upwards into the edge of a table or some solid metal. This almost always loosens the disc and you can spin the nut off with your fingers.

You can do it the opposite way as well left hand, disc facing right and drive it downwards.

Caveat I have safety glasses on when I do this and the grinder is unplugged or battery is out.

I've saved myself and many apprentices long walks back to the shop when no one has a wrench.

Obviously I use the wrench whenever it is available. It's the best method of disc removal.

Universal spanner and extra nuts that fit any angle grinder that uses a 5/8"-11 threaded arbor. That includes most 4" to 7" handheld angle grinders.

I also have an open end wrench to fit cup brushes.

The method in post 24 works pretty good, too, with a little practice.

I like to put a light coating of copper based neversieze on the arbor threads. It helps.

It definitely does. I feel it needs a disclaimer. DO NOT DO THIS ON DISCS YOU WISH TO RESUSE. IT WILL BREAK OR DAMAGE THE DISC.
