0.1250" (1/8) 3.175mm Diamond Flute Carbide Router, .472" LOC, Up Cut, Drill Point, 1/8" Shank R146

This 1/8" (0.1250") 3.175mm diamond flute carbide router features a .472" 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 multi-edge cutting structure that distributes cutting forces, resulting in smoother finishes and reduced chipping in brittle and abrasive materials.

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

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

This tool features a drill point tip, providing reinforced cutting strength for plunging, making it ideal for repeated entry into tougher materials without premature tip wear.

The .472" LOC offers a balance of cutting depth and tool rigidity for controlled performance.
