4 Flute Roughing End Mill For Steel With AlTiN Coating High Performance Carbide Router Bit For CNC Milling

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.

• 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.

• Faster Machining - Aggressive cutting geometry allows for higher feed rates without sacrificing tool life.
• Reduced Vibration - Engineered flute design ensures smoother operation in challenging materials.
• Longer Tool Life - AlTiN coating significantly reduces wear, lowering production costs.
• Versatile Performance - Suitable for dry or wet machining conditions.

• 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.

• Advanced grinding machines: All of our grinding machines are WALTER and SAACKE brands.
• Advanced inspection machines: We have ZOLLER, OMEGA, PG1000, etc. For inspecting each carbide tools.
• Fast feedback: we offer 24 hours online service
• Strict quality control system: We strictly adhere to a three-stage inspection process for each tool: Raw material inspection, Semi-finished product inspection after production, Final inspection after coating (pre-shipment check)
