Recommendations for use:

Observe the recommended rotational speed
When drilling metals, use a high-quality cutting oil or cooling lubricant, if possible. This facilitates smooth running and extends the drill tool life. Exception: when working on aluminium, use kerosene instead of cutting oil
In order to avoid corrosion, remove any particles which develop when working on stainless steel (INOX) from the work piece
Clean the work piece chemically or mechanically (etching/polishing, etc.).
