🛠️ What Are Diamond-Cut Router Bits with Fishtail Tips?

These tools feature:

• Diamond-patterned flutes: The flutes have a diamond-shaped geometry that allows for precision cutting with smooth sidewalls and minimal top-edge burr formation
• Fishtail tips: The fishtail design helps eliminate fracturing and prevents back-side breakthrough, making them ideal for plunge cuts in delicate materials.

📌 Key Benefits

• Minimizes Delamination and Fracturing: The unique flute design gently cuts materials without causing delamination, cracking, or fraying, which is crucial when working with composites and PCBs.
• Clean Edge Finish: Provides smooth sidewalls and minimal top-edge burrs, reducing the need for post-processing.
• Ideal for Abrasive Materials: Suitable for cutting hard and abrasive materials like carbon fiber, G10, FR4, fiberglass, ceramics, and more.

✅ Best Suited For

• Printed Circuit Boards (PCBs): Ensures precise cuts without damaging delicate components.
• Carbon Fiber and Composites: Maintains structural integrity during cutting.
• Fiberglass and G10/FR4: Prevents edge chipping and delamination.
• Ceramics and Graphite: Handles brittle materials with care, minimizing fractures.

⚠️ Not Ideal For

• Soft Woods and Foams: The flute geometry may cause tearing or rough finishes in softer materials.
• Metals: Not designed for cutting ductile metals like aluminum or steel.
• High-Speed Cutting: Due to their design, they are better suited for controlled, precise cuts rather than rapid material removal.

📊 Summary Table

In summary, diamond-cut spiral router bits with fishtail tips are specialized tools designed for precision and care when working with brittle, abrasive materials. Their unique design ensures clean cuts, minimizes damage, and extends tool life, making them invaluable in industries dealing with composites, PCBs, and similar materials.
