OPERATION
Your drill press is to be used with drill bits with a shank of 1/2" or less in diameter. The following will give the inexperienced
operator a start on common drill press operations. Use scrap material for practice to get a feel of the machine before
attempting regular work.
WARNING: The use of accessories and attachments not recommended by Delta may result in risk of injury.
IMPORTANT:
When the workpiece is long enough it
should always be positioned on the table with one end
against the left side of the column, as shown in Fig. 30.
This prevents the workpiece from rotating with the drill
bit or cutting tool, causing damage to the workpiece or
personal injury to the operator. If it is not possible to
support the workpiece against the column, the
workpiece should always be fastened to the table using
clamps or a vise.

INSTALLING AND
REMOVING DRILL BITS
1.
DISCONNECT MACHINE FROM POWER SOURCE.
2.
Insert smooth end of drill bit (A) Fig. 31, into chuck
(B), as far as it will go, and then back the bit out 1/16",
or up to the flutes for small bits.
3.
Make certain that the drill bit (A) Fig. 31, is centered
in the chuck (B) before tightening the chuck with the key
(C).
4.
Turn the chuck key (C) Fig. 31, clockwise to tighten
and counterclockwise to loosen the chuck jaws.
5.
Tighten all three chuck jaws to secure the drill bit
sufficiently so that it does not slip while drilling.
6.
MAKE SURE
chuck key (C) Fig. 31, is removed from
chuck before starting drill press. Your chuck key (C) is
equipped with a self-ejecting pin (D) which helps
minimize the hazard of the key being left in the chuck.
