Installation & Operation

1. Mount the bit securely in a compatible drill chuck, ensuring the hexagonal shank is fully seated and tightened.
2. Position the drill perpendicular to the work surface and align the self-feeding screw point with the desired hole location.
3. Start drilling at low speed to allow the screw point to engage and establish proper feed rate.
4. Maintain steady pressure while allowing the self-feeding design to draw the bit through the material.
5. Clear debris periodically during extended drilling operations to maintain optimal cutting performance.
6. Complete the hole and withdraw the bit slowly to prevent binding or damage to the finished opening.
