How to remove a disc from an angle grinder

A grinder is a universal tool that is used to solve various problems. For example, sharpening hacksaws, grinding stones and concrete, processing steel profiles, wood and other materials. Each operation requires a specific attachment - a disk. Knowledge about the design of the device and conversion skills will help solve this issue.

How to change a disc to an angle grinder

You will find a variety of attachments in building materials stores. Choose the one that meets the required tasks. Making a circle is not easy, but with certain knowledge and skill, everything will work out quickly.

Removal method with key

The machine always comes with an open-end wrench and instructions for use. It clearly describes the procedure to follow if it is necessary to replace the wheel:

1. Unplug the cord from the outlet.
2. Lock the button for stopping the rotating spindle.
3. While holding it, unscrew the flange nut with a wrench.
4. We remove the old disk and install the new one.
5. We secure it and tighten it with a universal key.

It is quite difficult to cope with the task alone. It's better to ask a friend for help.

After it is installed, turn on the machine for half a minute - maximum rotation speed. The disk should not dangle or hit the casing. Proper operation means proper installation.

Keyless

It often happens that a tool is lost or broken.Manufacturers do not bother to provide quality components. In this case, you will have to remove the disk without a key. And there are several ways to do this.

• Using an adjustable wrench. Just turn the nut a little, using almost no force. The disadvantage of this method is the possibility of damaging the rotational element.
• Chisel. The shaft is treated with WD 40 and wait 15 minutes. After this, they begin to carefully tap the circle using a chisel. It will take a long time, but it will begin to give in and soon it will be easy to unscrew by hand.
• Heated nut. Not a very safe method, but still effective. Using a torch, process the flange and carefully unscrew it with a glove. The danger is overheating, which will lead to boiling of the oil in the gearbox.

However, experts still advise using a special key to avoid injury. In addition, strictly follow safety precautions.

When the need arises

Replacement of the disc is required in case of damage to an already installed disc or the installation of other equipment is required. For example, if you were working with wood and now need to cut a steel pipe, you will need to replace the attachment.

How to properly install a disc on an angle grinder

Buy a circle that strictly fits the dimensions of the angle grinder. When installing a new nozzle, remove the protective cover and clean it thoroughly.

If the disk rotates clockwise, then the nut is unscrewed in that direction. The twisting will occur counterclockwise.

There are universal nuts on sale that are easy to unscrew without special tools. If you do not want to use additional keys, purchase this mount.

Otherwise, the main thing is to follow safety precautions.Work only with the tool turned off and de-energized, follow the instructions.
