The Vortex Carbide End Mill combines rugged carbide construction with a 3-flute square geometry, designed for machining hard materials up to HRc55. It’s a reliable choice for shops and professionals tackling demanding milling tasks with precision and durability.
- Diameter: 20 mm
- Flutes: 3
- End geometry: Square end for straight, accurate milling and flat-bottom pockets
- Material: Solid carbide for stiffness and wear resistance
- Material hardness capability: Suitable for materials up to HRc55
- Chip evacuation: Efficient chip removal for better cutting efficiency and tool life
- Stability and precision: Three-flute design provides excellent stability and accuracy during high-feed milling
With its 3-flute design and carbide composition, this end mill delivers dependable performance where others may struggle: it maintains tight tolerances, minimizes deflection, and preserves a consistent diameter through long cuts on hard metals. The square end yields clean, flat-bottom pockets and precise profiles, while efficient chip evacuation helps manage heat and buildup—resulting in smoother finishes, longer tool life, and less downtime in challenging applications such as mold making, aerospace components, and automotive parts. Ideal for profiling, slotting, and finishing in HRc55 materials, the Vortex end mill helps you complete tough jobs with confidence.
