PCB Application Guidance
| SELECTION FACTOR | GUIDANCE |
|---|---|
| Cutting Diameter | Select according to required slot width, contour detail and PCB feature size. |
| Flute Length | Use the shortest practical cutting length that provides sufficient board or stack depth to maintain tool rigidity. |
| PCB Substrate | Confirm FR4, Rogers, copper-clad laminate or other substrate because abrasiveness and board construction affect tool selection. |
| Dust & Chip Removal | Maintain effective extraction or air evacuation to remove fine PCB dust and chips from the cutting zone. |
| Machine Setup | Confirm spindle condition, toolholding, runout and routing depth before finalizing machining parameters for small-diameter tools. |
