2. Rotate the lower depth knob (3) until it rests against the bottom of the
metal gauge support (4).
Drilling an un-measured 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 21)
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 21 & 22)
1. Mark the desired depth (5) of the
drill hole on the side of the
workpiece.
2. With the drill press in the OFF
position, bring the drill bit (6) down
until the tip is level 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 depth scale lock
knob (1) 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.
