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. It seems like collets, tool holders and pull studs are 3 different pieces of tooling, however, when you load them to the spindle, all 3 becomes one solid piece. So make sure all 3 pieces meet certain standard, otherwise, if one piece is rough or goes bad, all others won't work right, that's why you may see large runout. Bad holders will scratch collets surface sooner, and reduce the life span and accuracy of collets. You can't use collets alone, and collets must be inside tool holders. In order to get couple tenth or half thousands total runout, both collets and tool holders must be running true by itself. 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.
