It had an Amana sticker on it but its not Amana quality. Collet not held in tight and its out of round. Amazon should look into who ever supplied this part. Its a joke.

I'm using this on a 1.5kw spindle on a CNC router and it works just fine. It's definitely not been balanced so don't expect that. Don't listen to reviews that say its not concentric. The collet nut has an eccentric ring for holding onto collets.

This appears to me to not an Amana product but a off brand but with a paper Amana sticker on the top. Also I see no evidence of it being balanced. Which is the whole reason I was willing to pay 4 times the price for a good brand that I thought would be balanced. Very disappointed. Will obviously be returning.

These ER20 collet nuts actually fit better than the ones that came with my CNC machine. I bought two of them just for replacement of my original ones that the machine builder supplied. I definitely recommend these and I'll likely buy two more just to have on the shelf.
