8.3 Depth stop
The depth stop is used for repetitive drilling of holes
of identical depth.
Depth stop can be established by one of two
procedures (see Figures 8-4 thru 8-6):
Method #1:
1. Loosen lock handle (H).
2. Use downfeed handles (D) to lower the bit until
it just contacts the top surface of workpiece, as
shown in Figure 8-5.
Figure 8-5: method #1
3. Hold downfeed handle in position, and rotate
scale ring (K) to zero. This sets the workpiece
surface as your zero reference point.
4. Move workpiece out from under bit, and rotate
downfeed handle to lower bit until scale ring (K)
reads your desired depth.
5. Hold downfeed handle in this position, and
rotate lock ring (J) counterclockwise as far as it
will turn. You should be able to feel and hear
when the lock ring reaches the end of its
rotation.
6. Tighten lock handle (H).
7. The bit can now be repeatedly lowered to the
pre-set depth using the downfeed handles.
8. To release the depth stop, loosen lock handle
(H).
Figure 8-4
Method #2:
1. Mark the desired depth of cut on the side of the
workpiece (Figure 8-6).
2. Loosen lock handle (H) and use downfeed
handle (G) to lower the bit to the mark. Hold
downfeed handle in position.
3. Rotate lock ring (J) counterclockwise as far as
it will turn. You should be able to feel and hear
when lock ring reaches the end of its rotation.
4. Tighten lock handle (H).
5. The bit will now stop at the marked depth when
the downfeed handle is rotated.
6. To release depth stop, loosen lock handle (H).
Figure 8-6: method #2
NOTE: Method #2 allows rapid, fine adjustment to
the setting, as follows:
If the depth setting is found to be too shallow :
7. Hold downfeed handle (G) stationary while
slightly loosening lock handle (H).
8. Slightly rotate downfeed handle to lower bit to
the more accurate position.
9. Retighten lock handle (H). Depth is now set to
more accurate position.
If the depth setting is found to be too deep :
10. Loosen lock handle (H) while holding downfeed
handle stationary.
