This Kyocera 1.50mm (.0591") chip breaker carbide PCB router features an 8.00mm (.315") length of cut, fish-tail tip, up-cut spiral, 1/8" shank, and 1.50" overall length. Made from solid tungsten carbide, it is designed for precision routing of FR-4, G10, fiberglass, phenolic laminates, and other rigid composite materials.

Part of Kyocera's Series 2300 Chipbreaker Updraft Router family, this tool uses interrupted cutting edges that break chips into smaller fragments during machining. The up-cut design helps evacuate chips and debris from the cutting zone.

Chip Breaker Geometry and Fish-Tail Tip

  • Spiral chip breaker: Helps improve chip control and reduce debris accumulation.
  • Up-cut spiral: Directs chips upward and away from the cutting area.
  • Fish-tail tip: Provides end-cutting geometry for PCB profiling and controlled through-cutting, helping reduce exit-side breakout when the material is properly supported.
  • 8mm (.315") LOC: Provides cutting reach for board outlines, slots, and composite routing.
  • Solid carbide: Provides rigidity and wear resistance when machining abrasive laminates.

The fish-tail configuration is useful for PCB outline routing, depaneling, and through-cutting operations where edge quality matters. Proper backing material and workholding help minimize splintering and laminate damage.

Typical Applications

  • PCB outline routing and depaneling
  • FR-4 and G10 fiberglass laminates
  • Phenolic laminate cutting
  • Precision slots and internal PCB contours
  • Through-cutting rigid fiberglass sheets
  • Selected carbon fiber composite routing applications

Carbon fiber and highly abrasive materials: Extended machining of abrasive composites can accelerate cutting-edge wear on uncoated carbide. For demanding production applications, consider a compatible diamond-coated router.
