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's 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 workpiece.
• Clean the workpiece chemically or mechanically (etching/polishing, etc.).
