ER-16 Headstock
ER-16 collet nut included.
Product Description
For use on a Sherline lathe or mill in place of the standard headstock if you are wanting an ER-16 spindle.
Keep in mind that if the ER-16 nose is ordered, no Sherline accessories that use a #1 Morse taper or 3/4-16 thread will work on this spindle.
The ER-16 nut that ships with your order may be plain or have a black oxide finish.
NOTE: We do not sell the collets used with the ER-16 spindle. Those are available through MSC Industrial Supply Co. or other tool supply sources.
