Stop Stud
The Model G7943/G7944 has a depth stop that
allows you to drill repeated non-through holes to
the same depth every time.
The depth stop consists of a stud attached to the
quill with two hex nuts that can be lowered or
raised on the stud so the lower nut (depth nut)
hits a stop bracket when the drill bit is lowered.
The upper hex nut (jam nut) is then used to
tighten against the depth nut to secure it in place
so it doesn't move with repeated operations.
Figure 29 shows the various components of the
depth stop.
Depth Stop
To set the depth stop:
1. Lower the drill bit to the required height.
2. Thread the depth nut down against the stop
bracket.
3. Lower the jam nut against the depth nut.
4. Using wrenches, hold the depth nut in place
and tighten the jam nut against the depth
nut.
Note: The scale on the depth stop can be recali-
brated if it gets moved or has changed since the
factory setting. Refer to Calibrating Depth Stop
on Page 38 for instructions on how this is done.
