OPERATION
Page 16
To adjust drilling depth (Fig. 23)
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 upper depth knob (2) until the
bottom of the knob is aligned with the desired
depth mark (5) on the gauge scale.
2. Rotate the depth scale lock knob (1) until it
meets the lower depth scale knob (2). The chuck
will stop after travelling downward to the selected
distance.
To adjust quill (return) height (Fig. 23)
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 (3) until it rests
against the bottom of the metal gauge support
(4).
DRILLING BLIND HOLES
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. 24)
1. Make sure the 0 (" or mm) mark on the depth
gauge rests at the top edge of the metal support
(3) 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 lower depth knob (2) until it is
aligned with the desired depth mark (4) (for
example, 1") on the gauge scale.
5. Rotate the upper depth lock knob (1) until it
meets the lower depth knob (2). The chuck will be
stopped at the distance selected on the depth
scale.
Workpiece method (Fig. 24 and 25)
1. Mark the desired depth (5) of the drill hole on
the side of the workpiece.
2. With the bench drill press in the OFF position,
bring the drill bit (6) down until the tip is even with
the mark.
3. Holding the feed handles at this position,
rotate the lower depth knob (2) until it meets the
metal support.
4. Rotate the upper (1) depth scale lock knob
until it meets the lower knob (2). The chuck and
the drill bit will now be stopped at the distance
selected on the depth scale.
DRILLING SPEEDS
Important factors when determining the best
drilling speed:
• Material type
• Hole size
• Drill bit or cutter type
• Quality desired
Smaller drill bits require greater speed than large
drill bits. Softer materials require greater speed
