Vortex End Mill 3 Flute Long Length Centre Cutting 30 Helix TiSiN Coated For 55HRC - 4mm

Meet the Vortex End Mill — a 4 mm, three‑flute, long‑length, center‑cutting milling tool designed for precision in hard materials. Built for CNC operators and machinists, it delivers dependable performance in steels up to 55 HRC and tough alloys, with a TiSiN coating that enhances wear resistance and longevity.

• Diameter: 4 mm
• Flute count: 3‑flute design for efficient chip evacuation and smoother cutting
• Cutting type: Center cutting for plunging and contour milling
• Helix angle: 30° helix geometry for stability and reduced tool deflection
• Coating: TiSiN coated for increased hardness, wear resistance, and lower friction
• Material compatibility: Suitable for materials up to 55 HRC, ideal for hardened steels and tough alloys
• Length: Long length provides extended reach for deeper pockets and complex geometries

This end mill is engineered to tackle demanding machining tasks without sacrificing accuracy. The center‑cutting design enables plunging into pockets or slots without retracting the tool, while the 30° helix minimizes deflection and vibration for cleaner finishes. The TiSiN coating boosts tool life in hard materials and reduces heat buildup, helping you achieve consistent tolerances across multiple passes. Whether pocketing, contouring, or slotting in hardened steels, the Vortex 4 mm end mill offers reliable performance and repeatable results.
