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