I have a simple upgraded 3018 machine and these nuts are better balanced and thread in futher than the stock ones. Overall a good upgrade that easily handles the high speed 20k rpm and isnt loud. Works great.

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

Ideal um nicht dauernd, beim Wechsel, die Spannzangen herauszubuhlen.

Sceptical of a previous review by a user of this product I held off on testing these as they claimed to be unballanced.To my surprise these ER20 nuts are very well balanced and nothing of it is "off center" other then the intended design of this nut.Running at 24000 RPM without a single issue and would buy again in my books!

I have a hobby cnc in my shop and was getting really tired of swapping collets out of the nuts all the time when using multiple bits on a project. Getting a set of these nuts let's me have all my common collet sizes in their own nuts, saving me time and annoyance.

These work without any issues. I only needed one but it's good to have extras.
