0.0625" (1/16" / 1.60mm) Kyocera Chip Breaker PCB Router, .200" LOC, Fish Tail, Up-Cut, 1/8" Shank | R158

This Kyocera 0.0625" (1/16") chip breaker carbide PCB router features a .200" (5.08mm) length of cut, fish-tail tip, up-cut spiral, 1/8" shank, and 1.50" overall length. The cutting diameter is approximately 1.59mm, commonly designated 1.60mm.

Manufactured from solid tungsten carbide, this precision router is designed for machining FR-4, G10, fiberglass, phenolic laminates, and other rigid composite materials.

Chip Breaker Geometry and Fish-Tail Tip

• Spiral chip breaker: Interrupted cutting edges help break chips into smaller pieces and reduce debris accumulation.
• Up-cut spiral: Directs chips upward and away from the cutting area for efficient chip evacuation.
• Fish-tail tip: Provides end-cutting geometry suitable for PCB profiling and controlled through-cutting, helping reduce exit-side breakout with proper workpiece support.
• .200" LOC: Suitable for board outlines, narrow slots, and shallow-to-moderate-depth composite routing.
• Solid carbide: Provides rigidity and wear resistance when routing abrasive laminates.

The fish-tail configuration is particularly useful for PCB outline routing and through-cutting where edge quality is important. Use appropriate backing material and controlled cutting parameters to minimize burrs and laminate damage.

Typical Applications

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

Carbon fiber and highly abrasive materials: Extended cutting in abrasive composites can accelerate tool wear. For demanding production applications, consider a suitable diamond-coated router.
