15.7.1 Clamping the Workpiece

In order to secure the workpiece against unintended movements due to drilling operation, use
appropriate devices like vice or clamping claw.
Put a wooden or plastic plate under the workpiece to avoid drilling into the work table or vice.
Use the drill depth stop if you need the same depth of drilling for multiple holes.

15.7.2 Drilling

Crushing hazard! Do not wear work gloves when drilling, but wear tight fitting work
clothes and, if necessary, a hairnet. Never put your hands between drill head and
pinole.
In terms of drill speed, please take note of the following rule: The larger the drill
diameter and the harder the metal, the lower the speed! Note the drill manufacturer's
details!
The speed is determined by gear lever and rotary direction switch. The cutting speed depends on
the hardness of the drill and the strength of the material to be processed. Common guidelines for
