How to use

Select an appropriate drill speed and, if drilling metal, apply cutting fluid or coolant to reduce heat and extend tool life. Secure the workpiece and use a centre punch on metal or mark the drilling point on other materials to prevent wandering. Insert the Proline 58140 into the drill chuck, tighten securely, and drill with steady pressure. Clear chips periodically and avoid excessive feed that may cause bit breakage or poor hole finish.

Usage recommendations

For best results, match drill speed and feed to the material: lower speeds and lubricant for metals, higher speeds for softwoods and plastics. Use appropriate personal protective equipment and clamp workpieces to ensure accurate, safe drilling.
