You probably have Angle grinder or as they say "Bulgarian". Or you are planning to purchase it for personal needs for sawing metal or grinding. Or even to mow the grass. Yes Yes I adapted something like a grinder for these purposes. So, when working with this miracle device, there is a chance of losing a special key for unscrewing the disk.
But it doesn't matter, there are ways to do without it. Now I will tell you about them, and you will surprise your colleagues at work or at your construction site with these moments. At one time, experienced, high-class installers and welders told me about them.
Interesting fact
In order to tighten the special disk on the angle grinder, you do not need to have a special key. It is necessary to screw the nut onto the installed disk, fix the stopper against rotation and by hand force, pull the disk with the nut. This results in a perfect tightening of the abrasive "stone".
We turn off the disk without a key, the first way
When working on any objects, you may lose a special key for the grinder. In this case, you can use a punch. We install the drill into the hole on the nut. We translate the puncher into slotting mode. With one hand, hold the stopper at the back of the gearbox. With the other hand we hold the perf and by short pressing the start button we unscrew the clamped nut. The method is proven, highly effective.
Second way
We need any wooden surface, we clamp the stopper with a finger and light blows on a tangent, with a disk on a piece of wood, in the direction of turning away, screw the circle together with a nut.
On the gif, a more understandable process.
The third way, with a gas key. Most common among plumbers. You should also tighten the stopper. And rotate the clutch with a gas wrench.
But keep in mind. The lever is large, which can cause the stopper to break off when biting the disc. But that is another story.
