- Regular checks are needed for worn parts and tool integrity.

#### Drill Bit Selection Guidance
|
||||
|
||||
Choosing the right drill bit (end mill) is essential for clean, efficient cuts and depends on your material and the operation:
|
||||
|
||||
- **Bit Diameter:**
|
||||
- 6mm (default) is versatile for general cutting.
|
||||
- Use smaller bits (e.g., 3mm) for detailed work.
|
||||
- Larger bits (e.g., 12mm) for faster rough cuts on thicker materials.
|
||||
|
||||
- **Upcut Bit:**
|
||||
- Best for fast chip removal.
|
||||
- Leaves a rough top surface but clean bottom.
