DRILLING HOLES TO DEPTH
When drilling one or two holes to a predetermined
depth, the calibrations on the face of the depth stop
rod (F) Fig. 7 can be used.
When drilling a number of holes to a predetermined
depth, or if a more exact setting is required, proceed
as follows:
1. Raise the locking sleeve (A) Fig. 7, and turn the
micro-nut (G) to the desired position on the stop rod
( F ) .
2, Lower the locking sleeve (A) so it will engage
micro-nut (G) Fig. 7. Lock sleeve (A) in place with
thumb screw if drill press is mounted in other than
vertical position. When the drill press is mounted with
t h e c h u c k p o i n t i n g “ u p ” , the locking sleeve (A) and
micro-nut (G) Fig. 7, should be reversed on the stop
rod (F).
3. When locking sleeve (A) is in place on the micro-
nut (G) Fig. 7, the micro-nut cannot be turned. When
a change in depth is required, the locking sleeve (A)
must be raised, and while it is raised, turn the micro-
nut (G) the necessary calibration marks. Each mark
represents .002”. Then lower the locking sleeve (A).
4. The use of the micro-set stop nut will maintain the
same hole depth, no matter how many holes are to be
drilled. However, we recommend that the hole depth
be checked whenever a drill has to be sharpened or
changed.
SAFETY SUGGESTIONS FOR
DRILL PRESSES
1 . I F Y O U A R E N O T t h o r o u g h l y f a m i l i a r w i t h t h e

9. BE SURE chuck key is removed from the chuck
before turning on power.
10. ADJUST the table or depth stop to avoid drilling
into the table.
