Hello, I've been trying to see what's wrong with my rotary tool. It makes a lot of noise on power option 3-4, but sounds healthy on 1-2 or 5-6. I tried taking off all attachments and tighten the spindle as hard as I could and the rotary tool sounded healthy on all power options.
I've come to the conclusion that the diameter of the dremel attachments don't allow me to tighten the spindle lock all the way which makes the sound unbearable at some levels. I've been thinking I might need another collet but would like some information before I buy.
The attachments (I've tried with several) are said to be compatible with my rotary tool. pic related.
Whens the last time you changed the oil in it?

It's practically new, and I have a feeling it can't be the oil when it sounds fine without any attachments.
When assembled like this the sound is unbearable at medium settings

And without the cutting disc in I can tighten the black spindle lock thing further making it quiet.
