0.0945" (2.40mm / 3/32") Kyocera Chip Breaker PCB Router, .394" LOC, Drill Point, Up-Cut, 1/8" Shank | R170

This Kyocera 2.40mm (.0945") chip breaker carbide PCB router, nominally 3/32", features a 10.00mm (.394") 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.

Part of Kyocera's Series 2300 Chipbreaker Updraft Router family, this tool uses interrupted cutting edges that break chips into smaller fragments during machining, helping improve chip control and evacuation.

Chip Breaker Geometry and Drill-Point Tip

• Spiral chip breaker: Helps reduce chip accumulation and clogging during routing.
• Up-cut spiral: Directs chips upward and away from the cutting zone.
• Drill-point tip: Provides pointed cutting geometry for controlled plunge-entry operations.
• 10mm (.394") LOC: Provides cutting reach for board profiling, slots, internal contours, and routing thicker 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 appropriate 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 reinforced composite sheets
• Controlled plunge-entry applications
• Selected carbon fiber composite routing operations

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