Vortex Long Neck Flat 2 Flute End Mill - TiSiN Coated - Square Edge - 0.4mm cutter dia x 4mm Reach

Engineered for high-precision CNC routing and fine detail work, the Vortex Long Neck Flat End Mill features a micro 0.4mm cutting diameter paired with a 4mm reach. This specialized tool is designed for machinists and makers who need to mill deep, narrow slots or create intricate patterns in soft materials like PCBs, plastics, and soft alloys.

• Cutter Diameter: 0.4mm fine tip for intricate detailing and small-scale milling operations.
• Reach Length: 4mm long neck extends cutting capability into deep pockets and recessed areas below the surface level.
• Flute Design: 2-flat flutes optimized for efficient chip clearance when cutting soft and non-ferrous materials.
• Coating: TiSiN (Titanium Silicon Nitride) coating provides a hard, low-friction surface that reduces heat buildup and extends tool life.
• Edge Geometry: Square flat bottom edge creates sharp, 90-degree corners and clean vertical walls for accurate profiles.

This tool solves the challenge of milling deep, narrow cavities without excessive tool deflection or breakage. The long neck design allows access up to 4mm deep, while the 2-flute geometry keeps cutting edges clear of debris during continuous cuts. The TiSiN coating ensures a smooth, polished finish on workpieces made of aluminum, copper, brass, or FR4, making it essential for electronics prototyping, micro-machining, and fine modeling tasks.
