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

The Vortex End Mill is a high‑performance cutting tool engineered for precision machining in hard materials. Designed for machinists and toolmakers, it combines a 3‑flute centre‑cutting design, a 30° helix, and a TiSiN coating to deliver reliable, long‑lasting performance in steels up to 55HRC.

• Diameter: 4 mm
• Flute count: 3‑flute design for efficient chip evacuation and smoother cutting
• Cutting style: Centre cutting for plunge and contour milling
• Helix angle: 30° helix geometry to improve stability and reduce tool deflection
• Coating: TiSiN coating increases hardness, wear resistance, and lubricity
• Material compatibility: Optimized for high‑hardness applications, suitable for steels up to 55HRC
• Application focus: Ideal for pockets, slots, and complex contours in hardened materials

The Vortex End Mill translates its robust design into tangible benefits: efficient chip evacuation minimizes heat buildup, preserving edge life and delivering cleaner finishes. The 30° helix works with the three flutes to maintain rigidity and reduce chatter, even in demanding passes. Center cutting enables straightforward plunge milling and versatile contouring, making it a go‑to tool for precise pockets and intricate cavities. TiSiN coating enhances edge hardness and wear resistance, helping you get more productive cycles between tool changes while maintaining consistent performance on hard materials.
