An easy way to unscrew the nut of an angle grinder

A fairly common problem for those who use an angle grinder is that the cutting disc breaks and the clamping nut is tightly clamped. And the most interesting thing is that it is sometimes almost impossible to unscrew the nut, either with a special angle grinder, or a gas wrench, or anything else. And if you manage to do this, then it takes enormous effort and wasted time. I will show you a simple way to save your time and effort in order to unscrew this angle grinder nut without unnecessary difficulties.

A simple way to unscrew the nut of an angle grinder

To unscrew the nut, the first step is to break off the remains of the broken cutting disc at the root.

This can be done very simply with pliers. Do not forget about protective equipment: glasses and gloves, as various small fragments fly.

In the end it should be like this:

Now we need to find a piece of metal that will be thinner than the grinder disc.

Turn on the angle grinder and use this piece to grind off the remaining disc between the nuts.


After everything has been ground off inside, the nut is unscrewed not only with a wrench, but even with your hands.



This is a very simple and very fast way.In addition, grinders are safe for bearings, because if the nut does not unscrew, most people immediately take a hammer in their hand and start trying to unscrew the nut by tapping.

What can be done to prevent this from happening again?

In order to avoid this situation again, you can place a plastic, paper or cardboard washer under the nut before clamping the new disk. And in such a case, the nut can always be unscrewed without any problems.


Nowadays it is not always possible to find cutting stones or discs of the required quality and therefore their breaking becomes a frequent problem. Of course, the human factor of improper operation cannot be ruled out. But now, if you find yourself in a similar situation, you know what to do. See you again!
