Vortex Long Neck Corner Radius 2 Flute End Mill - TiSiN Coated - 3mm Cutter Dia x 20mm Reach x 0.5 Corner Radius

Engineered for precision CNC machining, this Vortex long neck corner radius end mill combines a 20mm reach with a 0.5mm corner radius to create smooth, rounded internal features in deep pockets. Coated with TiSiN, the tool delivers extended cutting life and reduced friction when milling 3mm wide contours in aluminum, steel, and various alloys.

• Precise Specifications: Designed with a 3mm cutter diameter, 20mm effective reach, and a precise 0.5mm corner radius for accurate profiling of internal geometries.
• TiSiN Surface Treatment: The bronze-colored titanium silicon nitride coating significantly enhances edge hardness, reduces cutting friction, and improves thermal stability during aggressive milling operations.
• Deep Access Capability: The long neck design reaches into deep slots, recesses, and confined pocket areas, preventing tool deflection and avoiding collisions with part walls.
• 2-Flute Efficiency: The optimized two-flute geometry ensures clean chip evacuation and minimizes chatter, guaranteeing a reliable and smooth surface finish on the workpiece.

The extended reach enables machinists to machine deep internal cavities without tool interference, maintaining dimensional accuracy and reducing vibration. The TiSiN coating minimizes heat buildup and built-up edge formation, which is essential for high-speed milling in both soft and semi-hard materials. By consistently leaving a precise 0.5mm rounded corner, the end mill eliminates sharp internal stress concentrations. This makes the tool highly effective for producing durable end parts in aerospace, mold & die, and automotive manufacturing where fatigue resistance is critical.
