4.12.1 Fitting the drill chuck
The drill chuck is secured in the drill spin-
dle against turning over by means of a
form-locking connection (driver).
A frictionally engaged connection keeps
and centres the drill chuck or the drill in the
drill spindle.

Check and, if necessary, clean the conical seat in the drilling spindle and at the taper man-
drel of the tool or the drill chuck.
Press the taper mandrel into the drill spindle.
4.13 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 deliv
-
ery 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.
