DRILLING HOLES
TO DEPTH
Where a number of holes are to be drilled to exactly the
same depth, the stop nuts on the threaded stop rod are
used as follows:
1. Lower the spindle until the pointer (A) Fig. 25, lines
up with the mark on the scale (B) you wish the depth to
be. Then thread the lower stop nut (C) down to contact
the depth stop (D) on the side of the head. Return the
spindle to the up position and tighten the upper stop nut
(E) against the lower stop nut (C).
2. Drill a test hole to check the adjustment and re-
adjust if necessary. All holes will be drilled to the depth
indicated by the setting of the lower stop nut (C) Fig. 26,
as it contacts the depth stop (D) when the spindle is
lowered.

IMPORTANT: When the workpiece is long enough it
should always be positioned on the table with one end
against the column, as shown in Fig. 27. 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.
OPERATION
The following directions 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.
