- Zapojení děrové pily: Once the pilot drill has penetrated the material, gently apply pressure to allow the hole saw teeth to engage the workpiece.
- Udržujte stálý tlak: Apply steady, even pressure. Avoid excessive force, which can cause overheating or binding.
- Use Coolant (for Metal): When cutting metal, it is highly recommended to use a cutting fluid or coolant to extend the life of the hole saw and improve cutting efficiency.
- Průhledné čipy: Periodically withdraw the hole saw from the cut to clear chips and allow the saw to cool, especially when cutting deep holes or tough materials.
