Cooling
The friction generated during rotation can cause the edge of the tool to become very hot.
The tool should be cooled during the drilling process. Cooling the tool with a suitable
cooling lubricant ensures better working results and a longer edge life of the tools.
This is best realised by a separate cooling equipment. If there is no cooling equipment included
in the delivery volume, you can cool by means of a spray gun or a washing bottle.
CAUTION!
Danger of injury due to brushes getting caught or pulled in.
Use a spray gun or a washing bottle for cooling.
INFORMATION
Use a water-soluble and non-pollutant drilling emulsion as a cooling agent.This can be acquired
from authorised distributors.
Make sure that the cooling agent is being collected.
Respect the environment when disposing of any lubricants and coolants.
Follow the manufacturer’s disposal instructions.

Before starting work
Before starting work, select the desired speed. It is depending on the used drilling diameter and
on the material.
"Determining the cutting speed and the speed“ on page 83
WARNING!
For drilling jobs, it is necessary to
clamp the workpiece firmly to
prevent the bit catching on the
pieces. A machine vice or clamping
claws is a suitable clamping device.

Put a wooden or plastic board beneath the workpiece to avoid drilling through to the work table,
vice, etc.
If necessary, adjust the desired drilling depth with the drill depth stop to obtain a constant result.
When working with wood, make sure to use an adequate dust extraction unit, as sawdust can
constitute a health hazard. Wear a suitable dust mask when performing works at which dust is
generated.

During work
The spindle sleeve is advanced by means of the star wheel. Make sure that the feed is constant
and not too fast.
The spindle sleeve is returned to its initial position by the return spring.
