Seizing of clothes and / or hair.
Make sure to wear well-fitting work during drilling work.
Do not use gloves.
If necessary, use a hairnet.

INFORMATION
The smaller the bit the more easily it may break.
In the case of deep drilling, remove the bit from time to time to remove filings from the drill. Add
a few drops of oil to reduce friction and prolong the service life of the bit.
4.4
Cooling
CAUTION!
Danger of injury due to brushes getting caught or pulled in. Use a spray gun or a
squeeze bottle for cooling, or the coolant system of the machine.
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. Use a spray
gun or a squeeze bottle for cooling the tool.
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.
