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.
