Instrucciones de funcionamiento
- Comience a perforar: Position the pilot drill bit on the marked center of the hole. Start the drill at a low to medium speed.
- Engage Hole Saw: Once the pilot drill has penetrated the material, gently apply pressure to allow the hole saw teeth to engage the workpiece.
- Mantener una presión constante: 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.
- Chips transparentes: 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.
- Completar el corte: Continue drilling until the hole is complete. Reduce pressure as you near the end of the cut to prevent breakthrough shock.
- Remove Slug: After cutting, carefully remove the circular slug from inside the hole saw. Many Lenox hole saws feature side slots for easy slug removal.
Nota: The optimal drilling speed varies depending on the material being cut. Generally, harder materials require slower speeds, while softer materials can tolerate higher speeds. Refer to your drill's manual for speed settings.
Mantenimiento
- Limpieza: After each use, clean the hole saw to remove any debris, metal chips, or cutting fluid residue. A wire brush can be used for the teeth.
- Inspección: Regularly inspect the teeth for wear, damage, or dullness. A dull hole saw will cut slowly and generate excessive heat.
- Almacenamiento: Store the hole saw in a dry environment to prevent rust. Keep it in its original packaging or a tool case to protect the teeth from damage.
- Lubricación: For long-term storage, a light coat of rust-preventative oil can be applied to the metal surfaces.
