Don't drop any good collets into those rough and junk tool holders.
The total run out is holder and collets combined
If one goes bad, you'll see large run out and won't be running true


See two video below, the indicator is same, which is 0.0001", first video shows my tool holder with collets is about 0.0003" accuracy, then the 2nd video shows tool holders alone are 0.0001", you do the math, so the run out of collets is 0.0003-0.0001", my promise on collets are 2 to 3 tenth. Total runout is holder and collets combined, so you may need a good set of tool holder as well in order to run collets true

T.I.R.: 0.0003" or 5um. In order to make all collets running true, on your side, make sure your machine spindle and chuck holder running true, on my side, I'll make sure all those collets running in tenth.  


Seems like all sellers claim their collets are in 3-5 tenth, but yes or no, only customers can tell. Copy other sellers products description is easy, but make all collets running true is difficult. If you bought collets with more than 2 thousands run out, don't think I'm selling the same.

Special angled slots increase rigidity


Better overall balance of tool holder assembly


Protects tool holder from contaminants


Use with any standard ER collet chucks for coolant-thru tool applications.
