Router Bits
Choose from PCB router bits, CNC router bits, diamond flute routers, chip breaker routers, diamond-coated routers, down-cut routers, and router bit sets for abrasive composites, FR-4, G-10, fiberglass, carbon fiber, plastics, laminates, and other precision routing applications.
Router bit geometry affects edge quality, chip control, tool life, heat buildup, and material compatibility. Use the categories below to select the router style best suited for your material and application.
Choosing the Right Router Bit Geometry
Different router bit geometries are better suited for different materials and cutting priorities. For PCB routing, FR-4, G-10, fiberglass, carbon fiber, phenolic laminates, plastics, and composite sheet goods, the right router bit can improve edge quality, reduce chipping, control heat, and extend tool life.
- Diamond flute router bits: a good choice for PCB materials, FR-4, G-10, fiberglass, phenolic, and brittle laminates where clean edges and reduced breakout are important.
- Chip breaker router bits: useful for tougher or thicker materials where chip control, efficient cutting, and longer tool life are priorities.
- Diamond coated router bits: selected for improved wear resistance in abrasive materials such as carbon fiber, fiberglass, PCB materials, and composite laminates.
- Down-cut router bits: used when top-edge finish is important and a downward cutting action is preferred.
- Router bit sets: convenient when you need multiple sizes for testing, production backups, or common CNC routing jobs.
Not sure which router bit style to choose? Start by matching the tool geometry to the material being cut, then consider whether your priority is clean edge quality, faster material removal, reduced chipping, or longer tool life.
