Happy with 2nd batch sent to me.First batch i ordered was horrible manufacturing quality. the pull stud wouldn't thread into one of the holders and was off center in 2 others. the wrench slots in the nuts to tighten down the collets had been made too small so my standard collet wrench wouldn't fit into the slots, grind quality on the taper was poor. Then i chucked them up with a precision pin and spun them in my Haas mill spindle to measure tool runout and got anywhere from .003" to .012" total runout from all the holders. (I used name brand ER32 collets to make sure it wasn't my tooling messing up the measurement)second batch was then sent to me as a replacement. i am super happy with this set. The side holders identifying etches were in different locations and the machining marks were completely different. Night and day difference. It doesn't even look like these collet holders were made by the same manufacturers! all the pull studs threaded in and seated perfectly with the holders, my collet wrench fit the nuts, the grind finish on the taper was completely acceptable, all holders were .0003-.0005" total runout when measured on the same Haas mill.This seller has free returns so If you are willing to spend the time checking to make sure what you got is the good ones these are an excellent set for the price.
