Running True at High Speed turningFit all R8, morse tapper, CAT BT CNC ER32 chuck or holderFree Shipping in USDon't drop any good collets into those rough and junk tool holders.The total run out is holder and collets combinedIf 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

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.
