I should have paid attention to the other reviewer who said the accuracy was poor. I'm also measuring several thou of runout on these. A few thou of runout on a 1/8" bit is not acceptable. I measured 0.0015" runout on one collet, then 0.003" on the next, then 0.0025", and knew this set wasn't going to work. I'm returning this.

Reading the reviews for cheap ER collets on Amazon shows that there can be real issues with accuracy of the products no matter who sells them. The whole idea for collets is that they are an accurate way to hold a tool or a part. I took a chance on this seller. The parts are clean, look great, and are well packaged. The problem is that they do not run true. I put dowels in 4 sizes of the set shipped. They ranged from being +/= .002 inches to +/- .008 inches ( I could see the end wobbling as it turned). I wondered if my dowels or my indicator setup was the cause so I switched to Hardinge 5C collets and showed little or no measurable inaccuracy in my setup. Therefore the error of the ER collets in this set were 10 to 40 times the error of a properly machined collets. I am returning these collets.

My bad. They didn't fit my router. Which is too bad, because I was really impressed with weight and fell of these collets.

Work exactly as expected. I've only used 3 so far, but all appear to be good quality, with a low price tag. Couldn't ask for more. Thank you.

These are well built, accurate and nicely finished. The company cares about putting out a quality product and it shows. Great work! I would buy these again.

Very happy with this set so far. Very close tolerances for a snug fit with my R8 ER20 chuck from across the ocean. Finish is good. I primarily use the 3/8" collet, but I also use 5/32, 1/4, and 5/16 collets, and I have had zero problems so far. Using on a HF mini mill.
