Drill Chuck
Figure 12.
To mount the drill chuck on the drill press:
1. Thoroughly clean all of the oil from both ends
of the arbor, inside the drill chuck and the drill
press spindle.
2. The short taper on the end of the drill chuck
arbor is called a ‘Jacobs Taper’. In this case,
a ‘Jacobs Taper #3’. Slide the short taper into
the drill chuck and tap lightly with a soft ham-
mer or block of wood.
3. The long taper of the drill chuck arbor is
called a ‘Morse Taper’. In this case, a ‘Morse
Taper #3’. Slide the arbor and chuck into the
drill press spindle and turn it until the
tang
slips into the slot in the spindle.
4. While holding onto the drill chuck, tap lightly
on the bottom of the chuck with a soft ham-
mer or a block of wood. The drill chuck
should now be quite snug in the drill press. If
not, repeat steps 1-3, making sure all oil is
removed.
