4.2

Cooling

CAUTION!
Danger of injury due to brushes getting caught or pulled in. Use a spray gun or a wash-
ing bottle for 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. 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.
4.3

Before starting work

Before starting work, select the desired speed. It is depending on the used drilling diameter and
on the material.
INFORMATION
The data of the speed tables are guide values. In some cases it may be advantageous to
increase or decrease these values.
When drilling a cooling or lubricating agent should be used.
For stainless materials do not center as the material would compact and the drill bit will become
rapidly blunt.
The workpieces need to be tensed inflexibly and stably (vice, screw clamp).
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.
