   I can't remember details at this point. I've had them a while now. Going down my list of reviews that need done...I will say that these have 0 evidence of being balanced. I purchased these over less expensive options specifically for the balance claim.There were burrs, big ones where the drive dog slot is.I did measure runout outside of their spec (.0004 measured vs .00015 max claimed)  on the inside of the collet taper.I also desperately needed these, and ran them anyway. They are now reserved for shower drill and tap duty. When running them at 15k, there is a noticeable vibration in my machine.Overall, I am not happy with them, but I suppose I got what I paid for.
