So I'm about to cut the top off of my keg.. and when I put my cutoff wheel on my angle grinder (I have never used one before) I noticed the wheel is not secured at all. The Nuts holding it in are tight, but the wheel has range to move in beaten the 2 nuts. Is that normal?
at first I thought it felt very unsafe, but I managed to talk myself into thinking it was normal and that when the blade spins at such a rate, it should keep the wheel level..
I start to cut and the wheel starts wobbling all over the place and I cant imagine thats normal.. or safe.. so I quickly stop..
Im worried about over tightening the nuts so i haven't really tried to get it tight, but it does seem to want to stop at a certain point..

please help

Are you screwing the nut on straight, or perhaps missing a spacer, because that is definitely not normal, and definitely is dangerous.

you are not using the proper nut, or its not locked down. no slack should be there at all - additionally a angle-grinder generally uses thick discs which is not going to make for a nice cut. use a Dremel or a pneumatic cut-off wheel....

Thats a dangerous freakin tool, if your not sure about the operation of it using it could result in a trip to the ER at best and a prosthetic at worse

Take the nut back off and flip it over and seeif it tightens up they are made to hold different thickness of cut off wheels.

Try flipping the nut around and see if that secures it. On my grinder the nut is concave on one side and I have to use that side facing the cutting wheel when using thin disks. If it's a thicker one (grinding wheel) it will secure it regardless of what side of the nut faces it.

If that doesn't work the disks you are using may have a bigger diameter hole in them that what your grinder should be using.

I had to flip over the nut on mine as well. Don't know if this is technically the right thing to do, but I tightened it well and had no issues.

wow, even quicker than I expected..

Well this is a brand new makita 4 1/2 inch angle grinder, I am using all the nuts and parts that came with the tool. It came with a thick grinding wheel like hayabusa mentioned, but it also came with a "bonus" thin general purpose diamond blade. and I cant get that secure either..

I'm going to try to over tighten it and see if its just suck on something...

edit.. ok or try flipping the nut around.. thats probably it..

This is how my dewalt is. it is correct. The nut goes one way for the thick grinding wheels and the other way for thinner cutoff wheels.

They sell cut off wheels for angle grinders not just the thick grinding wheels. The cutoff disk he most likely bought was designed FOR his grinder.

It's the same thing as using a pneumatic cut off wheel.
I would like to see someone take a dremel to a keg. Call me next week when you're done.
