The HPL drill has a distinctive shaped point made from hard tool metal. This shape helps the drill centre itself to prevent it from faltering and to enhance the disposal of drilling material. Keep in mind that the sheet must not start smoking while drilling the hole. To prevent this, you can start drilling slowly and increase the drilling speed gradually. A tip: drilling into Trespa® sheets requires a bit of practice. If possible, use a disposable piece of HPL to practice on.
