OPERATION
GENERAL DRILLING GUIDELINES - DRILLING A HOLE
WARNING
To prevent the workpiece and the backup
material from slipping from your hand while drilling,
position the workpiece and backup material to the left side
of the column. If the workpiece and the backup material are
not long enough to reach the column, clamp the workpiece
and backup material to the table. Failure to do this could
result in personal injury.
1. Mark where you want to drill in workpiece by using a
center punch or a sharp nail or turn ON the laser to mark
your drilling point.
2. Before turning the drill press ON, turn the feed handles
to bring the drill bit down. Line the drill bit tip up with the
mark. Clamp the workpiece in place.
3. Turn ON the drill press and pull down on the feed handles
with the appropriate force needed to allow the drill bit to
drill the material.
NOTE: Feeding too slowly might cause the drill bit to turn
in the chuck. Feeding too rapidly might stop the motor,
cause the belt to slip, force the workpiece loose, or break
the drill bit. Practice with scrap material to get the feel of
the machine before attempting to do any drilling operation.
ADJUST THE DRILLING DEPTH (FIG. 21A)
The depth gauge controls the maximum distance the drill bit
will move up or down.
TO STOP THE DRILL BIT AT A PRE-MEASURED DEPTH:
1. Rotate the lower depth scale knob (Fig. 21A - 2) until
the bottom of the knob is aligned with the desired depth
mark (Fig. 21A - 5) on the gauge scale.
2. Rotate the depth scale lock knob (Fig. 21A - 1) until it
meets the lower depth scale knob (Fig. 21A - 2). The
chuck will stop after travelling downward to the selected
distance.

POSITION THE TABLE AND WORKPIECE (FIG. 20)
Always place a piece of backup material (Fig. 20 - 1)
(wood, plywood, etc.) on the table underneath the workpiece
(Fig. 20 - 2). This will prevent splintering on the underside of
the workpiece as the drill bit
breaks through. To keep
the material from
spinning out of control,
it must contact the left
side (Fig. 20 - 3) of
3
the column as illustrated,
or be clamped
(Fig. 20 - 4; not included)
to the table.

NOTE: For small
workpieces that
cannot be clamped
to the table, use a
drill press vise
(not included).
The vise must be
clamped or bolted
to the table to
avoid injury.
TO ADJUST THE QUILL (RETURN) HEIGHT:
To adjust the upward distance the quill (shaft that moves up
and down) can travel:
1. Turn the feed handles until the quill
is at the desired height
and hold it there.
2. Rotate the lower
depth knob
(Fig. 21A - 3)
until it rests
against the
bottom of the
metal gauge
support
(Fig. 21A - 4).
Drilling an unmeasured
blind hole (not all the way
through the workpiece)
to a given depth can be
done two ways: using the
depth scale method or workpiece method.
DEPTH SCALE METHOD (FIG. 21B)
1. Make sure the 0 (in or mm) mark on the depth gauge rests
at the top edge of the metal support (Fig. 21B - 4) when
the quill is fully retracted.
2. Put the workpiece on the table and raise the table until
the tip of the drill bit just touches the top of the workpiece.
Lock the table in place.
3. Determine the drill depth for this workpiece.
4. Rotate the depth knob (Fig. 21B - 2) until it is aligned with
the desired depth mark (Fig. 21B - 3) (for example, 1") on
the gauge scale.
5. The chuck will be stopped at the distance selected on
the depth scale.
