The 5/32" chuck holds drills from 5/32" (4mm) down to #80 (.0135" or .343mm). It is designated "0JT" which stands for "Zero Jacobs Taper". This chuck comes with a #0 Jacobs tapered hole in the back. Into that Sherline has pressed a special arbor that provides either a #1 Morse taper to fit into the Sherline headstock or a #0 Morse taper to fit the tailstock.
A chuck key plus a drawbolt and washer are included with P/N 1010 to secure the chuck in position. These chucks are useful for holding very small drills and their shorter length provides an increase of about 1/2" in working space between centers on the shortbed lathe compared to the 1/4" drill chuck. Runout as specified by Jacobs is .004" or less.
NOTE: Because the arbor is pressed into the chuck, it is not interchangeable from chuck to chuck. A separate chuck must be purchased for #0 and #1 Morse use.
