Tip: When drilling or when tapping operations
need to be done deep into a part, the quill can
also be stabilized by slightly applying the lever to
add drag and preload to the quill.
To install a tanged drill or chuck:
1. lock the tailstock in position, then unlock the
quill.
2.
use the quill feed handwheel to extend the
quill about 1" out of the tailstock.
3.
insert an Mt#3 chuck arbor or drill bit into the
quill just until the tang drops into the slot and
the tapers just touch.
Tip: For maximum locking of large diameter drill
bits, push and seat the drill bit into the quill
with a clockwise rotation as to load the tang
against its slot.
4.
tap the end of the tooling or drill bit with a
wooden block or mallet to seat the tool.
5.
lock the quill.

To remove a tapered drill or chuck:
1. turn the handwheel counterclockwise until
the arbor or drill bit is pushed out from the
tailstock taper.
—if the tool is stuck in the bore and cannot
be removed by turning the handwheel with
moderate force, extend the quill to expose
the drift key slot, and use any standard drift
key to remove the stuck tooling.
