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:
- Rotate the upper depth knob (2) until the bottom of the knob
is aligned with the desired depth mark (5) on the gauge scale.
FIG.8.1
- 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.
FIG.8.1
To adjust the upward distance the quill (shaft that moves
up and down) can travel:
- Turn the feed handles until the quill is at the desired
height and hold it there.
- Rotate the lower depth knob (3) until it rests against the
bottom of the metal gauge support (4).FIG.8.1

9.2 WORKPIECE METHOD
- 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.FIG.9.1
-
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.
-
Determine the drill depth for this workpiece.
-
Rotate the lower depth knob (2) until it is aligned with the
desired depth mark (4) (for example, 1”) on the gauge scale.
FIG.9.1
-
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.
FIG.8.1
- Mark the desired depth (5) of the drill hole on the side of
the workpiece.FIG.9.2
- With the bench drill press in the OFF position, bring the
drill bit (6) down until the tip is even with the mark.FIG.9.2
- Holding the feed handles at this position, rotate the
lower depth knob (2) until it meets the metal support.
FIG.9.1
- 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.

9 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.
