Cutting wheels for angle grinders should always be installed with the image facing inward.
This was reported by the Zen channel “Dachny StroyRemont” with reference to an experienced plumber.
How to install a disc on a grinder
Take a cutting disc for an angle grinder and examine it carefully.
On the side of the disc where the pictures are located, you will see a small metal ring.
Turn the disk over and examine the other side, where there are no pictures. There is no metal ring there either.
So, the disk must be installed with the picture facing inward so that the metal ring touches the washer.
This will ensure a secure grip and prevent the disc from binding or wobbling.
