Adjusting Depth Stop; Adjusting Table - Grizzly G7945 Owner's Manual

Adjusting Depth Stop

The Model G7945/G7946 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 28
shows the various components of the depth stop.
The return height nut, on the base of the stud,
limits the downfeed handle return distance, which
is set by how high the nut is placed on the stud.
This feature is useful for repetitive drilling motions.
Note: The scale on the depth stop can be recali-
brated if it gets moved or has changed since the
factory setting. Refer to Depth Stop Calibration
on Page 37 for instructions on how this is done.
