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 Black and Decker 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.
TROUBLESHOOTING
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
to prevent it from turning. If the piece is of irregular shape and cannot be laid flat on the table, it should be securely
blocked and clamped.
