0.0197" (0.50mm) x .160" LOC TiN-Coated Diamond Flute PCB Router, Fish Tail, 1/8" Shank | RS-100

RS-100 TiN-coated diamond flute PCB router features a 0.0197" (0.50mm) cutting diameter, .160" (approximately 4.06mm) length of cut, 1/8" shank, and 1-1/2" overall length. This solid carbide router is designed for fine-detail routing, profiling, and trimming of printed circuit board laminates and abrasive composite materials.

The diamond-cut flute geometry uses multiple small, intersecting cutting edges to distribute cutting action along the tool. This makes it well suited to controlled routing of FR-4, G10, fiberglass, and phenolic laminates, where minimizing edge chipping and delamination is important.

The titanium nitride (TiN) coating provides a hard, wear-resistant surface that can help reduce friction and cutting-edge wear under suitable machining conditions. The coating does not make this a diamond-coated router.

Its fish tail tip is designed for PCB routing and outline cutting, while the up-cut configuration helps direct machining debris away from the cutting area. The extended .160" LOC provides additional cutting reach compared with shorter-flute 0.50mm routers, although careful control of cutting forces is particularly important at this small diameter.

Typical Applications

• Fine-detail PCB outline routing and profiling
• FR-4 and G10 fiberglass laminate machining
• Phenolic laminate trimming and contour cutting
• Precision slots and narrow contours in suitable composites
• Small-feature CNC routing and prototype work
• Routing operations requiring additional cutting reach at a 0.50mm diameter

Key Features

• 0.50mm cutting diameter: Suitable for miniature profiles and fine-detail routing.
• .160" length of cut: Provides additional cutting reach for suitable workpiece thicknesses and routing depths.
• Diamond flute geometry: Multi-edge cutting pattern designed for abrasive laminates and composites.
• Fish tail tip: PCB-routing tip geometry for controlled profile and outline cutting.
• Up-cut direction: Helps evacuate machining debris from the cutting zone.
• TiN coating: Hard, wear-resistant surface that can help reduce friction and cutting-edge wear.
• Solid carbide: Provides rigidity and wear resistance for precision routing.
• 1/8" shank: Compatible with properly sized precision CNC spindle collets.

Machining Recommendations

Due to its small 0.50mm cutting diameter and extended .160" cutting length, this router requires careful attention to spindle runout, feed rate, cutting depth, and workpiece support. Use a precision collet, secure the material firmly, and avoid excessive side loading or aggressive cutting passes to minimize tool deflection and breakage.

Important: Diamond flute refers to the multi-edge cutting geometry, not a diamond coating. The TiN coating provides additional surface hardness, but it is not equivalent to a diamond coating. For extended tool life when machining highly abrasive materials such as carbon fiber, consider diamond-coated tooling.
