For what they cost, go buy a new one and see what happens. If the new one has no vibe then toss out the old one.

My old die grinder seems to run smooth as silk when there is no bit / burr in it.
As soon as I put in a burr and turn it on, it has an out-of-round vibration. It's almost not enough to see with your eye but you can hear it and feel it, and when you try to put it to a surface to grind on, it jumps around in an unsafe manner.
The burr has a short 2-in shank and the diameter of the cutter head is only about 1/2 inch.
So the vibration must be from the burr. It was $23 twenty years ago and is brand new / undamaged.
Are the TIR tolerances that tight on a 26,000 RPM cutting burr ?
Where do you buy quality burrs these days that don't vibrate ? Here’s a post we had on Abodiesonly about burrs. I will be buying more in the future https://www.forabodiesonly.com/mopar/threads/killer-carbide-review-update-with-video.509680/page-3

I would get a new collet. that may very well be the way to go. i have seen collets deformed by tightening up on undersized tooling shanks. this can also booger up the female receiving cavity, possibly rendering the tool useless unless the output shaft of the tool is replaced. just my personal experience using these tools. your mileage will vary.
