12x12mm Tungsten Carbide Corn Teeth Router Bit for PCB (5–8mm Cutting Depth)

The 12x12mm Corn Teeth Router Bit is a premium-grade cutting tool designed for fast, clean, and efficient routing of PCB boards and other sheet materials between 5mm to 8mm thick. With its distinctive corn-style fluted cutting surface, this bit is engineered for aggressive material removal while minimizing burrs and heat buildup — ensuring smooth edges and reduced post-processing.

Crafted from solid tungsten carbide, the bit offers exceptional hardness, sharpness retention, and resistance to wear and thermal stress. Its 12mm cutting diameter and 12mm shank provide added rigidity and vibration control, making it ideal for CNC routers, engraving machines, and precision milling tools.
