How to use

Secure the appropriate 4 mm drill bit in the drill chuck until it is held firmly. Select the correct drill speed for the material—lower speeds for soft metals, moderate speeds for plastics and higher speeds for wood. Apply steady, even pressure and allow the bit to cut without forcing; withdraw occasionally to clear chips if drilling deep holes. After use, clean chips from the flute and store the set in its Quadro pack to protect the cutting edges.

Usage recommendations

Use appropriate personal protective equipment (safety glasses and gloves as needed), clamp workpieces securely, and choose drill speeds matching the material to extend bit life and ensure accurate holes.
