Wangdefu PCD Corn End Mill combines the ultra-hard wear resistance of polycrystalline diamond with a multi-tooth helical corn cutter design, developed for high-efficiency machining of non-ferrous materials such as aluminum alloys, copper alloys, carbon fiber composites, and high-silicon aluminum.
With a dense cutting edge layout and optimized chip evacuation structure, it enables rapid heavy stock removal while maintaining stable cutting performance, delivering both high material removal rates in rough machining and near-mirror surface quality in semi-finishing operations.
As a professional PCD cutting tool manufacturer in China, Wangdefu supplies reliable solutions widely used in new energy vehicles, 3C electronics, aerospace, and general machinery, making it an ideal choice for machining motor housings, camshaft bores, and composite structural components.
Why choose our products?
Ultra-Hard PCD + Reinforced Structure
Wangdefu PCD Corn End Mill uses 8000–10000 HV PCD cutting edges (8–12× harder than carbide) and 10–25 μm grain for excellent wear and chipping resistance. The welded alloy steel body with 16 cutting edges ensures maximum rigidity and high material removal rates.
Precision Edge + Optimized Helix
Edges are ground to ≤0.005 mm radius with chamfered corners to prevent chipping. 30°–60° helix angles reduce cutting forces and vibration, providing stable performance even at deep cuts.
Efficient Chip Evacuation and Cooling
Wide helical flutes and internal/external coolant support prevent chip buildup. Low-friction PCD ensures smooth cutting and keeps temperature below 750°C, solving aluminum adhesion issues.
Roughing and Semi-Finishing in One Tool
Material removal rate up to 60% higher than carbide, tool life 50–200× longer, and machining time cut by 50% for EV motor housings. Overall processing cost can drop ~40%.
Trusted China Manufacturer and Supplier
Wangdefu delivers high-performance PCD Corn End Mill for EVs, 3C electronics, aerospace, and general machinery, with bulk orders, customization, and reliable delivery.
