About the ER-16 Collet Headstock
For use on a Sherline lathe in place of the standard headstock if you need the holding power and economy of an ER-16 spindle. ER collets feature wide holding range of 0.039" (1 mm) which reduces the number of collets needed.
The ER-16 Headstock is designed to be interchangeable with the standard Sherline headstock. The centerline height and mounting system is the same.
A Lathe/Mill Headstock Spacer (P/N 1297) will be needed to raise the spindle height to the center height of the Mk-III Bed Turret.
