Troubleshooting

Drill bit breaks during drilling.

Reduce the drilling speed and pressure. Ensure the drill bit is perpendicular to the work surface. Consider using a pilot hole for thicker materials.

Drill bit is dulling quickly.

Check the material being drilled and adjust the drilling speed accordingly. Ensure the drill bit is being cooled properly. For metal, consider using cutting oil.
