0.0551" (1.40mm) Diamond Flute Carbide Router, .250" LOC, Up Cut, Fish Tail, 1/8" Shank R127

This 1.40mm (0.0551") diamond flute carbide router features a .250" length of cut, 1-1/2" overall length, and a 1/8" shank, offering excellent rigidity and control for precision routing applications.

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

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

The up-cut design improves chip evacuation and enhances bottom-edge cut quality, making it ideal for through-cuts and general routing.

This tool features a fish tail tip, designed for gentle entry and reduced delamination in brittle or layered materials.

The .250" LOC provides greater rigidity and reduced tool deflection, making it well suited for precision work and controlled-depth cutting.
