Work great
I bought these because my cnc machine came with only metric Collettes. I have several 1/4" bits. They fit perfectly. I will probably buy a couple 1/8" bits now.

Perfect for my CNC.
I have a TwoTrees TTC450 CNC w/ 500 watt spindle upgrade, and I wanted to have a spindle set for any bit I might have reason to use. This set is literally everything in SAE that will fit an ER11 collet, and I can order and use any bit without worrying about "Do I have a collet to fit?" Yes. Yes I do. Comes individually packaged, as well. 5 stars.

Out of spec collet - the 1/4" is really 6mm
I received these a couple of weeks ago and just tried using the 1/4" collet. It was extremely difficult to fit a bit with a 1/4" shaft in to the collet and after trying several times I discovered is not a 1/4 collet but a 6mm collet which is not useful. If they are going continue to sell these they need to advertise them correctly and not mislead their customers.
