3 4 6 Flute Carbide Corn Cob Roughing End Mill PCB Milling Cutter for Fiberglass Bakelite Circuit Board Engraving



Introduction:


Our Carbide Corn Cob Roughing End Mill is a specialized cutting tool designed for high-efficiency material removal in PCB (printed circuit board), fiberglass, Bakelite, and other composite materials. Featuring a unique serrated (corn cob) design, this end mill aggressively removes material while minimizing vibration, ensuring smooth, clean cuts in abrasive and brittle substrates. Ideal for CNC routers, engraving machines, and PCB prototyping, this tool delivers superior performance and extended tool life compared to standard end mills.


Features:


Multi-Flute Design (3/4/6 Flutes) – Optimized for fast chip evacuation and reduced cutting resistance.


Solid Carbide Construction – Provides exceptional hardness and wear resistance, ideal for abrasive materials.


Corn Cob (Serrated) Cutting Edge – Breaks chips efficiently, reducing heat buildup and preventing material delamination.


Precision Ground Cutting Edges – Ensures clean, fray-free edges on fiberglass, G10, and epoxy boards.


High-Speed Machining Compatible – Works with CNC routers, milling machines, and PCB engravers at high RPM.


Available in Multiple Sizes – Common diameters: 1.0mm, 2.0mm, 3.175mm (1/8"), 4.0mm, 6.0mm.



Advantages:


Faster Roughing & Material Removal – The serrated design allows deeper cuts at higher feed rates compared to standard end mills.


Reduced Vibration & Chatter – Corn cob geometry dampens harmonics, improving cutting stability.


Longer Tool Life – Carbide material resists wear, reducing tool changes and downtime.


Cleaner Machining of Brittle Materials – Minimizes fiber tear-out and edge chipping in PCBs and composites.


Versatile Applications – Suitable for both roughing and semi-finishing operations.



Typical Applications:


PCB milling & circuit board prototyping


Fiberglass, Bakelite, and epoxy composite machining


CNC routing of insulating materials & electronic enclosures


Engraving & slot cutting in plastics and reinforced polymers


Aerospace & automotive composite part manufacturing
