0.0938" (3/32" / 2.40mm) x .400" LOC Diamond Flute Carbide Router, Drill Point Tip, 1/8" Shank | R140A

This 3/32" (0.0938") 2.40mm diamond flute carbide router features a .400" length of cut, 1-1/2" overall length, and a 1/8" shank, making it ideal for deeper precision routing and repeated plunge applications.

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.

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

This tool features a drill point tip, designed for strong, precise plunging, making it well suited for repeated entry into tougher or denser materials.

The .400" LOC provides increased cutting depth while maintaining precision and control.
