Description of HHIP 3901 5090 ER 32 Collet Drawbar
Superior finish and craftsmanship. Made of 20CrMnTi alloy steel. Electrolysis nickel coating. Tolerance is .0003" maximum. Drawbar end thread is 5/8"-11.
Was poorly made and didn't fit exactly on the collets. I've ordered again and I hope it fits perfectly this time. EDIT: The new one is good! Must be a lemon!
