Product Overview
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.
Key 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
Performance 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
