How to use

Select a drill bit size appropriate for the required hole diameter and material. Secure the workpiece and clamp where possible to prevent movement. Insert the selected bit into the drill chuck and tighten according to the drill manufacturer’s instructions. For metal and hard materials, use a steady feed rate, appropriate cutting speed and, if needed, cutting fluid to reduce heat and extend bit life. For wood and plastics, use moderate speeds to prevent burning or melting. After use, allow the bits to cool before returning them to the case to avoid moisture buildup.

Usage recommendations

Use personal protective equipment such as safety glasses and gloves. Match drill speed and feed pressure to the material being drilled. Periodically inspect bits for wear or damage and replace any that show significant dulling or chipping to maintain drilling accuracy and safety.
