INSTALLING AND REMOVING DRILL BITS
NOTE: Use drill bits with a shank of 5/8" or less in
diameter.
To reduce the risk of injury, turn unit off
and disconnect it from power source before installing
and removing accessories, before adjusting or when
making repairs. An accidental start-up can cause injury.
1. Insert the smooth end of drill bit (L1) Fig. 46 in the
chuck (S1) as far as it will go, and then back the
bit out 1/16" (1.6 mm) (or up to the flutes for small
bits).
2. Center the drill bit (L1) Fig. 46 in the chuck (S1) before
tightening the chuck with the key (T1).
3. Turn the chuck key (T1) Fig. 46 clockwise to tighten
and counter-clockwise to loosen the chuck jaws.
4. Tighten all three chuck jaws to secure the drill bit
sufficiently to prevent slipping.
5. Remove the chuck key (T1) Fig. 46 from the chuck
before starting the drill press. The chuck key is
equipped with a self-ejecting pin (U1) which helps
minimize the potential for the key to be left in the
chuck.
REMOVING CHUCK AND SPINDLE ADAPTER
To reduce the risk of injury, turn unit off
and disconnect it from power source before installing
and removing accessories, before adjusting or when
making repairs. An accidental start-up can cause injury.
The spindle adapter and chuck can be removed for the
purpose of using shanks with a #2 morse taper.
1. Align the slot in the quill (V1) Fig. 47 with the slot in the
spindle (W1).
2. Insert the drift key (X1) Fig. 48 through the slot in the
quill and the slot in the spindle.
3. Tap the drift key (X1) Fig. 48 with a hammer until the
the spindle adapter and chuck fall from the quill.
CORRECT DRILLING SPEEDS
Factors that determine the correct speed are 1) the
workpiece, 2) the size of the hole, 3) the type of bit or
other cutter, and 4) the quality of cut.

DRILLING WOOD
To reduce the risk of injury, tighten all lock handles before starting the machine. Loss of control of the
workpiece can cause serious injury.
Twist drills, usually intended for metal drilling, can also be used for boring holes in wood. However, machine spur bits
are generally preferred for working in wood. These bits cut a flat-bottom hole and are designed for removal of wood
chips. Do not use hand bits (screw tip). At drill press speeds, they lift and rotate the workpiece.
For through boring, align the workpiece so that the bit will go through the center hole in 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 the drill bit slowly into the workpiece when the bit is close to cutting through the wood to prevent splintering the
bottom face. Use a scrap piece of wood as a base block under the work to reduce splintering and protect the point of
the bit.
