Vortex Long Neck Corner Radius 2 Flute End Mill - TiSiN Coated - 3mm Cutter Dia x 12mm Reach x 0.2 Corner Radius

The Vortex Long Neck Corner Radius 2 Flute End Mill is a precision CNC cutting tool engineered for deep cavity machining and contouring. Combining a 3mm cutter diameter with a 12mm length of reach and a 0.2mm corner radius, this tool is optimized for accessing recessed areas that standard end mills cannot reach. The visible bronze-colored coating indicates a TiSiN (Titanium Silicon Nitride) layer, while the long, slender neck geometry allows for greater depth of cut on narrow features without excessive deflection.

• Dimensions and Reach: The tool features a 3mm cutter diameter and a 12mm length of cut (reach). This long-neck design provides a 4:1 length-to-diameter ratio, enabling the machining of deeper pockets and cavities than a standard 3mm end mill of the same diameter.
• TiSiN Coating: The cutting edges and the long neck are coated with Titanium Silicon Nitride, visible as a metallic bronze finish. This coating offers high thermal stability and hardness, reducing friction and extending tool life during high-speed machining or when working with harder alloys.
• Corner Radius Geometry: Unlike a square end mill, this tool has a 0.2mm corner radius at the tip. This radiused edge reduces stress concentration on the tool and workpiece, preventing material breakout and delivering a smoother surface finish on the floor of the milled pocket.
• 2-Flute Optimization: The two-flute design creates large chip flutes. For a long-reach tool like this 12mm reach end mill, efficient chip evacuation is critical to prevent chips from getting stuck, recutting, or causing overheating deep in the pocket.
• Shank Design: The tool terminates in a straight, cylindrical uncoated shank (silver finish) suitable for secure clamping in standard collets or ER clamping systems, ensuring concentricity and accuracy during operation.

This end mill addresses the challenge of reaching deep features in materials like aluminum, plastics, or non-ferrous metals while maintaining tool integrity. The TiSiN coating allows machinists to run higher feed rates and cutting speeds compared to uncoated tools, increasing productivity. The 0.2mm corner radius ensures the tool is strong enough for roughing and finishing operations without the weakness of a sharp corner. Whether used for mold making, prototype fabrication, or production milling, this Vortex end mill delivers the specific reach and durability required for complex 3D profiling.
