3.7. Drilling
With the tool mounted, use the gear lever to set the speed range corresponding to
the diameter of the hole to be drilled. Use the following relation among the speed,
diameter, and the type of the tool.

Set the rotation direction switch to position ‘R’, and start the motor using the green
MOTOR button. Slowly rotate the spoke handles to lower the cutter (or drill) to the
workpiece and gently begin drilling. Then,
use

conditions.
When drilling using annular cutters, accomplish holes in one pass. However,
drilling holes with diameters of 18
–32 mm (0.71–1.26’’)
using twist drills must be
performed in two passes. In such the case, drill a hole with the diameter of about 70 %
of the final diameter, and then perform the drilling again to finalize the hole to the
anticipated diameter.
When drilling holes deeper than 50
mm (2’’), retract the tool above the workpiece
as often as possible to allow the chips to be expelled from the hole. Additionally,
once the tool is retracted, clean the grooves of the tool using a small brush if they are
clogged. After exceeding 40 mm
(1.6’’) of the drilling depth, introduce the cutting fluid
into the milling area manually (from the bottle).
If the operation results in an overload, caused by not sufficient cooling, using dull
tool, or too fast feed in comparison to the tool diameter, the machine will automatically
stop. In such a case, to restart the machine, press the red MOTOR button, retract
the
tool from the workpiece,
and then press the green MOTOR button (the electromagnetic
base must remain powered).
Once the hole is accomplished, retract the tool from the workpiece, stop the
motor
using
the
red
MOTOR
button,
and disable the electromagnetic base by toggling
the MAGNET
switch to position ‘O’.
When the annular cutter goes through the material, the slug core
is expelled from the cutter with a significant force.
