4 Flute Roughing End Mill for Steel with AlTiN Coating High
Performance Carbide Router Bit for CNC Milling
Introduction:
The 4-Flute Roughing End Mill with AlTiN Coating is a premium-grade carbide cutting tool designed for aggressive
material removal in steel and other tough metals. Engineered with a high-efficiency 4-flute design and AlTiN (Aluminum Titanium Nitride) coating, this end mill delivers exceptional durability, heat resistance,
and extended tool life in high-speed CNC machining applications.
The specialized roughing geometry ensures reduced vibration,
improved chip evacuation, and superior surface finish, making it
ideal for heavy-duty milling operations.
Features:
✔ High-Performance AlTiN Coating – Provides extreme heat resistance (up to 900°C) and reduces friction, offering 3X longer tool life compared to uncoated or TiN-coated end mills.
✔ 4-Flute Design for Roughing – Optimized for high material removal rates (MRR) while maintaining stability and reducing chatter in steel and
alloy machining.
✔ Solid Tungsten Carbide Construction – Ensures maximum rigidity, wear resistance, and precision for
demanding CNC milling applications.
✔ Variable Helix & Pitch Geometry – Minimizes vibration and harmonics, enabling smoother cuts and
improved surface finish.
✔ High-Speed CNC Compatible – Precision-ground for excellent balance and concentricity, suitable for high-RPM machining centers and CNC routers.
✔ Coolant-Ready – Compatible with flood coolant or MQL (Minimum Quantity Lubrication) for enhanced heat dissipation and chip control.
Advantages:
Applications:
✅ Carbon & Alloy Steels – Including pre-hardened steels (up to HRC 45).
✅ Stainless Steel (303, 304, 316) – Ideal for roughing and semi-finishing.
✅ Cast Iron & Ductile Iron – High-efficiency milling for automotive and industrial parts.
✅ Tool & Die Making – Mold bases, cavities, and heavy machining operations.
✅ General Metalworking – Aerospace, automotive, and heavy machinery components.
