Collet nut for ER-16 collets and micro mills with an ER-16 Spindle like the HiTorque Micro Mill. Holds ER-16 collets and has and internal thread of M22*1.5. The outside diameter is 1.1" (28 mm) with a tightening diameter of 0.98" (25 mm) across the flats. The collet nut has a black oxide finish.
*Collet must be assembled into a collet chuck nut before inserting into the collet chuck.
With all ER collet chucks, the collet must be snapped into the nut before placing it into the chuck. There is an eccentric ring inside the nut that engages the groove in the collet. That is what makes them self-ejecting. Tilt the collet again to remove it from the nut.
