Carbide Tungsten CNC Router Bits Corn Cutter Cutting End Mill
Introduction:
Our 4mm & 6mm carbide end mills are specially designed for PCB (printed circuit board) machining, offering superior precision and durability for CNC engraving, routing, and milling applications. Featuring a corn tooth (corn cob) flute design, these tungsten steel cutters ensure efficient chip evacuation, smooth cutting performance, and extended tool life, making them ideal for FR4, copper-clad laminates, and other PCB materials.
Features:
✔ High-Quality Tungsten Carbide Material
Ultra-fine grain carbide substrate for maximum hardness and wear resistance
Maintains sharp cutting edges longer than HSS or coated alternatives
✔ Optimized Corn Tooth (Corn Cob) Flute Design
Aggressive chip removal to prevent clogging and heat buildup
Reduced cutting resistance for smoother engraving
Ideal for high-speed PCB milling (up to 30,000 RPM)
✔ Precision Ground Cutting Edges
Ultra-sharp edges for clean, burr-free traces on PCBs
Consistent diameter tolerance (±0.01mm) for accurate machining
✔ Available in 4mm - 6mm Diameters
Covers most PCB routing needs (traces, slots, holes, and edge trimming)
Compatible with standard CNC engraving machines and routers
✔ Excellent Heat & Wear Resistance
Withstands high-speed machining without edge degradation
Longer tool life compared to standard PCB bits
