CNC Router Bits for Carbon Fiber
Carbon fiber laminates are extremely abrasive and can quickly wear standard carbide tools. When machining carbon fiber on a CNC router, specialized cutting tools are recommended to maintain clean edges and maximize tool life.
Tools Commonly Used for Carbon Fiber CNC Machining
- Diamond-coated carbide routers
- Diamond-flute carbide routers
- Chip-breaker routers for thicker laminates
Diamond-Coated Routers
Diamond-coated routers provide the longest tool life when machining abrasive composite materials such as carbon fiber, fiberglass, G-10, and PCB laminates. These tools are commonly used in aerospace, motorsports, and composite fabrication.
Diamond-Flute Routers
Diamond-flute carbide routers can also cut carbon fiber effectively and are often used when lower tool cost is preferred or when machining smaller production runs.
Tips for Machining Carbon Fiber
- Use high spindle speeds and light passes
- Ensure good dust extraction
- Avoid dull tools which can cause fraying
