Angle grinder. the most dangerous power tool

The discs on the angle grinder are fixed with a nut, which is twisted in the same direction in which the spindle of the power tool rotates. And when the rotation stops abruptly, the locking nut self-tightens.

In order to unscrew it later, an effort is required that is much higher than that which arose during the wedge, and it is simply impossible to do this with a “native” or gas key.

Step number 3

Unscrew and remove unnecessary residues of the consumable

Obstacle removed, now you can unscrew the nut and remove what remains of the cutting disc. The nut is unscrewed easily, in most cases this can be done by hand, without using a tool.

Preventive measures

A cardboard washer will allow you to unscrew the nut after any emergency situations

This method is simple and convenient, but still it’s more convenient not to break anything, but just unscrew it. In addition, there are times when the discs are just tightly clamped. It’s a long time to break a stripping abrasive with a thickness of 5 mm, and then grind it under the nut, because there is a method to avoid the situation where it will be impossible to unscrew the nut with a wrench.

To do this, you only need to make a gasket washer from cardboard.

Cheap and cheerful

The tool is ready to go.
