General Information
The feed rate and spindle speed
are decisive for the service life of
the bit.
- The cutting speed is determined by the
speed of the drill spindle and by the
diameter of the bit.
- In principle, therefore, the larger the
bit diameter, the lower the speed that
should be selected.
- For workpieces of greater strength, the
cutting pressure must be higher.
- Repeated withdrawal of the bit enables
easier chip removal.
- Chip removal is especially difficult in
deep holes. Reduce the feed rate and
speed in this case.
- To avoid excessive wear on the cutting
surface of the bit, for drill holes over
8.0 mm in diameter you should first
drill with a bit with a smaller diameter.
Switching on and off
Make sure that the power supply
voltage matches the voltage rating
indicated on the device‘s type pla-
te.
Connect the machine to the power
supply.
Switching on:
Press the on switch (2).
Switching off:
Press the off switch (1).
Emergency stop:
Press the emergency stop button (5).
After pressing the emergency stop
button, the emergency stop button
(5) must be activated again by
turning it. Press the on switch (2) to
restart the device.
Clamping the Workpieces
Only work with workpieces that can be
securely clamped. The workpiece must not
yield too much. Otherwise it is nor possib-
le to apply adequate tension.
The workpiece must not be too small or too
large either.
Removing Blockages
- You should always select a suitable
feed rate which allows trouble-free chip
breaking.
- If the bit is jammed in the workpiece,
turn off the power and unplug the po-
wer cord. Turn the bit on the drill chuck
anticlockwise with a little jerk to break
the chip and release the bit again.
- If a fragment is produced during the
processing of the workpiece, turn off
the power and unplug the power cord.
Use a pair of pliers and remove the
fragment to prevent it flying off in an
uncontrolled way.
