Diamond Flute Routers

Diamond flute routers are optimized for abrasive laminate materials such as FR-4, G10, and fiberglass, providing excellent edge quality and clean cuts.

For carbon fiber: Due to its extreme abrasiveness, diamond-coated routers are the recommended choice for longer tool life and reduced edge wear.

Chip Breaker vs Diamond Flute Routers — when to use each →

Diamond Flute (diamond-cut) routers remove material using a fine, multi-edge cutting pattern that is gentler on brittle and fracture-prone materials.

  • Best for: PCB materials (FR-4), fiberglass, carbon fiber, phenolic laminates, abrasive composites
  • Why choose it: minimizes chipping, delamination, and material fracture while maintaining edge durability
  • Tip options:
    • Fish Tail tips are often preferred for delicate entry into brittle materials
    • Drill Point tips are commonly used where repeated plunging or added tip strength is required

Use the filters below to narrow results by diameter, flute geometry, plunge tip type, and cut direction to find the exact tool you need.
