See two videos below, the indicator is the same 0.0001", two videos show the run out of holder alone and holder with collets, as you can you see, holder alone is about 0.0001", then combined runout of holder with collets are 0.0003". My promise is total run out is less than 5 tenth, so both holder and collets are running true.
