How to use

Secure the drill bit in a compatible drill chuck and tighten according to the drill manufacturer's instructions. Select an appropriate drilling speed and apply steady pressure while keeping the drill perpendicular to the workpiece to ensure a clean, accurate 4 mm hole. Use cutting fluid or coolant when drilling metal to reduce heat and extend the bit's life. After use, clean any debris from the flutes and store the bit in a dry place.

Usage recommendations

For best results when drilling metal, start with a pilot mark and use moderate speed with light, steady pressure. Apply cutting fluid to improve chip evacuation and reduce wear. Replace the bit if it shows signs of dulling or chipping to maintain hole accuracy and safety.
