Fits perfect and works great
Perfect fit, appears to be quality material that will allow me to quickly and easily swap different collets on the spindle.

Handy to have
I got tired of swapping collets out of my one spindle nut so I bought these. Now I just leave each size collet in it's own spindle nut. Definitely speeds up tool changes.I did see other reviews complaining about the inside machining was off center. Mine too was off center and for half a minute thought I'd have to return them. But then I inserted a collet and instantly realized the purpose. That off-set hole allows for much easier removal of the collet from the spindle nut. Checked the tool bit with a dial gauge in the spindle and it was right on.My only one complaint is the hex nut shape is a little smaller than the original and my wrenches slip off sometimes but all I need to do is slow down and it's fine.

Nice Collet Nuts
Revised my review. The collets nuts work fine, my issue was resolved by pushing the collet into the collet nut first, then inserting the CNC bit I wanted to use before installing in the machine spindle. If you try to insert the collet with a bit installed it will not be able to snap into the ride in the collet.After having trouble with these I purchased a $25 Amana collet which looks to be a Chinese collet with a Amana label slapped on the package. Quality looks to be the same as these.

Works as intended
Bought these for a Nextwave CnC router. Fits the spindle and works as well as the OEM holder.

Not balanced
Fit finish and threads are good. However they are definitely not balanced!

No detectable runout or misbalance. Working well so far
I was nervous these would be low quality given how affordable they are. That was not the case. These collet nuts appear to be working as well as the much fancier polished one that came with my spindle.It appears the low reviews maybe didnt know how to operate an ER style collet\nut. Other reviews have covered it, but you have to snap them in without a tool.Just ordered another 4 of these!
