The Vortex Carbide End Mill is a precision milling tool designed for metalworkers and CNC operators who demand durability and accuracy in hard metals. With a 1 mm diameter, a 3-flute square-end geometry, and a 45° edge configuration, it excels in challenging milling applications up to HRc55. Diameter: 1 mm Flute Count: 3-flute configuration for rigidity, stable cutting, and efficient chip evacuation Edge Geometry: Standard square end with 45° edge configuration for versatile milling Material: Solid carbide construction for high hardness and wear resistance Workpiece Materials: Suitable for materials up to HRc55, including hardened steels Chip Evacuation: Optimized flute design promotes effective chip clearance to reduce heat and prevent built-up edge Designed to deliver consistent, precise finishes in tight features and pockets, this end mill provides excellent stability thanks to its three-flute geometry. The carbide composition delivers long tool life in hard metals, while the small 1 mm diameter enables detailed contouring, slotting, and micro-milling with fine surface finish. Whether you're producing hard-steel components, precision tooling inserts, or delicate prototyping parts, the Vortex 1 mm end mill helps you achieve accurate tolerances, clean edges, and repeatable results. For best results, match feeds and speeds to the material grade (up to HRc55) and use proper workholding to minimize vibration.
