0.0945" (3/32" / 2.40mm) x .394" LOC Diamond Flute Carbide Router, Fish Tail Tip, 1/8" Shank | R139

This 3/32" (0.0945") 2.40mm diamond flute carbide router features a .394" length of cut, 1-1/2" overall length, and a 1/8" shank, making it ideal for precision routing in abrasive materials.

The diamond flute geometry uses a fine, multi-edge cutting structure that is gentler on brittle and layered materials, helping reduce chipping and edge damage while maintaining consistent cutting performance.

Optimized for PCB materials (FR-4, G10), fiberglass, phenolic laminates, carbon fiber, and other abrasive composites, this tool delivers clean edges and reliable results in demanding CNC environments.
