Basic Drill Press Operation

Installing Drills

Insert drill into chuck far enough to obtain maximum grip-
ping of the chuck jaws. The jaws are approximately 1"
long. When using a small drill do not insert it so far that
the jaws touch the flutes (spiral grooves) of the drill. Make
sure that the drill is centered in the chuck before tighten-
ing the chuck with the key.
Tighten the drill sufficiently, so that is does not slip while
drilling.
Turn the chuck key clockwise to tighten, counterclockwise
to loosen.

Positioning Table and Workpiece

Lock the table to the column in a position so that the tip of
the drill is just a little above the top of the workpiece.
Always place a piece of backup material (wood, plywood,
etc.) on the table underneath the workpiece. This will pre-
vent "splintering" or making a heavy burr on the under-
side on the workpiece as the drill breaks through. To
keep the backup material from spinning out of control, it
must contact the left side of the column, as illustrated.
WARNING: To prevent the workpiece or the backup
material from being torn from your hand while drill-
ing, position them against the left side of the col-
umn. If the workpiece or the backup material are
not long enough to reach the column, clamp them
to the table. Failure to do this could result in per-
sonal injury.
For small pieces that cannot be clamped to the table, use
a drill press vise (optional accessory).
WARNING: The vise must be clamped or bolted to
the table to reduce the risk of injury from spinning
work and vise or tool breakage.
