Still waiting for my er32 collets to come in but with the exceptional finish on this holder I don't think I'll have to worry about any run out if I do I will let you know

The collet nut was not fully machined and makes the tool unusable. I contacted the seller but they refused to help me. Unusable product, Unhelpful seller. Don't buy from them!

I have purchased other ER20 collet chucks before and they had significant runout. This one had virtually none. Runout was 5microns (.0002") inside the taper when shank was trued up.
