Begin drilling with steady pressure, maintaining alignment to keep the drill centered and allow chips to clear. After use, clean the bit and store it in a dry place to prevent corrosion.
Usage recommendations
For best results when drilling metal, use a suitable cutting lubricant, moderate feed pressure, and lower speeds for harder materials. Inspect the bit regularly for wear and replace when cutting performance declines.
