0.0551" (1.40mm) x .275" LOC Diamond Flute Carbide Router, Drill Point Tip, 1/8" Shank | R128

This 1.40mm (0.0551") diamond flute carbide router features a .275" length of cut, 1-1/2" overall length, and a 1/8" shank, delivering a balance of strength and cutting depth for demanding 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 drill point tip, designed for increased strength and durability during plunging operations, making it ideal for repeated entry cuts and denser materials.

The .275" LOC provides a balance of cutting depth and rigidity, supporting both precision work and moderate-depth routing.
