3. Use a dial indicator or planed piece of stock
and feeler gauges to determine if all boring
bits are the same distance from the table.

removing the bit from the chuck, turning the
center screw of the bit (see
Figure 38), then
re-installing the bit into the chuck.

Adjusting Screw
Note:
Threading the adjusting screw into the
bit raises the working height of the boring
bit.
Aligning Boring Bit
Height
To ensure drilled holes are consistent in depth
along the length of the workpiece, the height of all
boring bits must be equal.
Note:
The table must be parallel to the boring
head assembly before aligning the boring bits.
Refer to
Adjusting Table Parallel to Boring
Head

Boring bits are sharp and can cut your
hands. Protect yourself by using a shop rag
to handle the bits during removal or instal-
lation.
2. Make sure that all boring bits are inserted
fully into the chuck.
Note:
This can be done by loosening the two
set screws that hold the bit into the chuck,
and, while applying moderate upward pres-
sure on the bit, re-tightening the set screws.
