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.).
