How to use

Secure the Proline 71416 drill bit in the chuck of a portable drill or drill press, ensuring the shank is fully inserted and tightened. Select an appropriate spindle speed and apply steady feed pressure; when drilling metal, use cutting fluid or lubricant to reduce heat and extend tool life. Start with a pilot mark or center punch for accurate positioning, and clear metal shavings periodically to maintain cutting efficiency. After use, clean the bit and store it in a dry place to prevent corrosion.

Usage recommendations

For best results when drilling metal, use cutting fluid, moderate speeds and controlled feed. For thicker materials, consider pre-drilling a smaller pilot hole. Inspect the bit regularly for wear and replace it when cutting performance declines.
