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.
Decent quality at reasonable price
