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 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 lubricants and coolants.
Follow the manufacturer's disposal instructions.
