5/32" Drill Chuck with #1 Morse Arbor
Product #: 1010
These chucks are designated “0JT” which stands for “Zero Jacobs
Taper”, because it comes with a #0 Jacobs tapered hole in the back. Into
that we have pressed a special arbor that provides a #1 Morse taper to
fit into the Sherline headstock. 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 compared to the 1/4″ drill chuck.
Runout as specified by manufacturer is .004″ or less but we try to
maintain .003″ or less in our testing process. If runout of less
than .003″ amount is required, collets should be used to hold the drill
rather than a chuck.
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.
