Fitting The Drill Chuck; Cooling - Optimum OPTidrill DQ 14 Betriebsanleitung

4.10.3 Fitting the drill chuck

Only a clean and smooth surface allows a correct and tight fitting connection.
On the bench drill DQ14, the drill chuck is pressed onto the taper B16.
On the DQ18 and DQ22 bench drills, the drill chuck is secured against rotation in the drill spin-
dle by a positive-locking connection (driver). A frictionally engaged connection keeps and cen-
tres the drill chuck or the drill in the drill spindle.

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.
