• Connection: quick-change HEX compatibility
• Compatibility: suitable for drills and impact drivers accepting 1/4" hex bits and magnetic bit holders

How to use

Select the appropriate drill bit size from the set for the metal and hole diameter required. Insert the 1/4" hex shank into the drill or impact driver chuck or magnetic bit holder until securely seated. Use appropriate cutting speed and moderate pressure for the metal type; apply cutting fluid or lubricant when drilling harder steels to extend bit life and improve chip evacuation. After use, wipe the bits clean and store them in their original case or designated holder to prevent damage and corrosion.

Usage recommendations

Wear eye and hand protection when drilling metal. For best results, start with a small pilot hole for large diameters, maintain steady feed rate, and use lubrication on harder alloys. Inspect bits regularly for wear and replace any that show dulling, chipping, or deformation.
