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-tightenting the set screws.
3.
Use a dial indicator or a planed piece of stock
to determine if all boring bits are the same
distance from the table.
4.
The height of a boring bit can be adjusted by
removing the bit from the chuck, turning the
center screw of the bit (see
Figure 39
), 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.
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.
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 before aligning the boring bits. Refer to
Adjusting Table Parallel to Boring Head on
Page 29
.
To align boring bit height:
