I bit the disc on the grinder, how to unscrew the nut while doing this

The grinder is an indispensable tool for various types of work. So much the worse when the tool crashes and the disc bites. In this case, it is not possible to remove the nozzle, as the nut is jammed. There is an easy way to twist a closed mount by heating, which we will discuss in the article.

How to remove a bite disc from a grinder

Problems most often occur when working with sturdy materials. When starting the angle grinder operates at a speed of 6000-12000 rpm. In contact with the treated surface, the disc receives the strongest resistance. Its work slows down somewhat, while the motor continues to turn in the same mode.

This leads to sharp screwing of the retainer nut into the spindle thread. It is no longer possible to unscrew it with the usual key.

How to remove the clamp

There are several simple methods that are used in the first place:

1. Insert a metal rod into the holes and try to rotate it with light hammer blows. The main thing is not to rip the holes or break the button.
2. Heat the fasteners. When the temperature changes, the technical parameters change slightly, and expansion occurs.
3. We grind the disc with another grinder until the nut unscrews.

These methods are effective, but not always. Therefore, there are more correct options for getting rid of the angle grinder from the fastening clamp.

A simple way to twist the nut

Using a thick piece of board, a stump, or a piece of timber, you can warm up the nut. To do this, the angle grinder is firmly pressed against the tree so that the nut continuously rubbed against the surface. We turn on the tool and hold it for 2-3 minutes. This time is enough for the mount to heat up.

Next, we clamp it using a regular key and unscrew it easily and freely. This happens due to the physical properties of metals to expand when heated. The method is very good, it works almost flawlessly.

How not to unscrew the nut

When the disc is pinched, the operator spends a lot of time releasing it. This leads to irritation of the person, as a result of which inappropriate ways to correct the problem are applied.

We will tell you how not to act when jammed:

• metal studs in the holes can loosen the grip, but more often they lead to huge load on the gearbox, resulting in damage to one of the structural parts of angle grinder;
• a nut of a larger diameter welded on top, torn off with a huge wrench, will damage the gear teeth and break the thread;
• heating with a gas burner is not the best option, this method is unlikely to help, but it will definitely violate the physical properties of the metal.

It is much easier and safer to cut off the clamped disc from both sides with the other grinder and unscrew the loose nut without any problems.

How to avoid pinching

Work tool problems are always best avoided. To do this, we work very carefully, making sure that the disc does not jam and break. We also recommend using special nuts. They are more expensive than ordinary ones, but they can be easily unscrewed in case of clamping.

Also, special gaskets are considered a hot product. Their price is up to 100 rubles, while they perfectly protect against jamming. You can do it yourself at home by cutting it out of the paranite.
