0.0625" (1/16") Kyocera Chip Breaker PCB Router, .315" LOC, Drill Point, Up-Cut, 1/8" Shank | R159

This Kyocera 0.0625" (1/16") chip breaker carbide PCB router features an .315" (8.00mm) length of cut, drill-point tip, up-cut spiral, 1/8" shank, and 1.50" overall length. Manufactured from solid tungsten carbide, it is designed for precision routing of FR-4, G10, fiberglass, phenolic laminates, and other rigid composite materials.

The spiral chip breaker geometry uses interrupted cutting edges to divide chips into smaller fragments during machining. Combined with the up-cut spiral, this helps improve chip evacuation and reduce debris accumulation when routing abrasive PCB laminates.

Chip Breaker Geometry and Drill-Point Tip

• Spiral chip breaker: Helps control chip formation and promote efficient debris removal.
• Up-cut spiral: Directs chips upward and away from the cutting zone.
• Drill-point tip: Provides pointed entry geometry for controlled plunge-entry operations using appropriate machining parameters.
• .315" LOC: Provides 8mm of cutting length for board profiling, slots, and routing suitably supported composite materials.
• Solid carbide: Provides rigidity and wear resistance when machining abrasive laminates.

The drill-point configuration is useful when a routing operation requires controlled entry into the workpiece. Use suitable plunge feeds, rigid workholding, and minimal spindle runout to help prevent tool damage.

Typical Applications

• PCB outline routing and circuit board profiling
• FR-4 and G10 fiberglass laminates
• Phenolic laminate cutting
• Precision slots and internal PCB contours
• Routing rigid fiberglass and composite sheets
• Controlled plunge-entry applications
• Selected carbon fiber composite routing operations

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