Quality, fit and finish appear a big step above the cheap Chinese collets. Price is great compared to usual tool supply houses.

As it moved loose in the nut the bit came off-center and broke the bit ruining the carving. Poor quality

Just feels great! Bit fits snug before even turning the nut. A single turn to remove the bit.

I've been using Er-20 collets on my CNC spindle for a few years. Like them very much.

I got these so that I could use imperial bits in my CNC. The spindle that I had came with Metric Collets. These have worked out just perfect.
