Held in the adjustable tailstock holder P/N 1203 (not included) you can now hold extremely small drills, accurately on center. Drills of only a few thousandths of an inch are easily broken if not perfectly centered.
The WW collet adapter holds Sherline WW collets that have a shank diameter of .312-.313″. Other manufacturers make collets that vary in size up to .314-.315″. The 8.0 mm adapter is made to hold collets of that size. If your collets are not made by Sherline, measure them carefully to see which adapter you should use.
Complete instructions are provided with the adaptor to help you "perfectly" align the headstock and tailstock of your Sherline lathe.
