GENERAL SAFETY RULES
Woodworking can be dangerous if safe and proper operating procedures are not followed. As with all machinery, there
are certain hazards involved with the operation of the product. Using the machine with respect and caution will
considerably lessen the possibility of personal injury. However, if normal safety precautions are overlooked or ignored,
personal injury to the operator may result. Safety equipment such as guards, push sticks, hold-downs, featherboards,
goggles, dust masks and hearing protection can reduce your potential for injury. But even the best guard won’t make
up for poor judgment, carelessness or inattention. Always use common sense and exercise caution in the workshop.
If a procedure feels dangerous, don’t try it. Figure out an alternative procedure that feels safer. REMEMBER: Your
personal safety is your responsibility.
This machine was designed for certain applications only. Delta Machinery strongly recommends that this machine not
be modified and/or used for any application other than that for which it was designed. If you have any questions relative
to a particular application, DO NOT use the machine until you have first contacted Delta to determine if it can or should
be performed on the product.

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. 28.
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.

(C).
4. Turn the chuck key (C) Fig. 29, clockwise to tighten
and counterclockwise to loosen the chuck jaws.
Fig. 29
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. 29, 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.
CORRECT DRILLING SPEEDS
Factors which determine the best speed to use are: kind of material being worked, size of hole, type of drill or other
cutter, and quality of cut desired.
WARNING: Use the recommended speed for the drill press bit and workpiece material.
BORING IN WOOD
Twist drills, although intended for metal drilling, may also be used for boring holes in wood. However, machine spur bits
are generally preferred for working in wood; they cut a flat bottom hole and are designed for removal of wood chips.
Do not use hand bits which have a screw tip; at drill press speeds they turn into the wood so rapidly as to lift the work
off the table and whirl it.
For through boring, line up the table so that the bit will enter the center hole to avoid damage to the table. Scribe a
vertical line on the front of the column and a matching mark on the table bracket and the drill press head, so that the
table and drill press head can be clamped in the center position at any height.
Feed slowly when the bit is about to cut through the wood to prevent splintering the bottom face. Use a scrap piece
of wood as a base block under the work; this helps to reduce splintering and protects the point of the bit.
DRILLING METAL
Use clamps to hold the work when drilling metal. The work should never be held in the bare hand; the drill bit may seize
the work at any time, especially when breaking through the stock. If the piece is whirled out of the operator's hand, the
operator may be injured. The drill bit will be broken if the work strikes the column.
The work must be clamped firmly while drilling; any tilting, twisting or shifting results not only in a rough hole, but also
increases drill bit breakage. For flat work, lay the piece on a wooden base and clamp it firmly down against the table
