Meet the Vortex Carbide End Mill, a 3-flute square-end tool crafted for challenging milling tasks on hard materials up to HRc55. Designed for CNC professionals and shops that demand precision, durability, and reliable performance in tough applications. Diameter: 3 mm Flutes: 3-flute design for improved stability and accuracy End geometry: Standard square edge for clean pockets, slots, and precision profiling Edge angle: 45° edge geometry (as specified in the product name) to support efficient cutting and chip control Material: Solid carbide, offering high hardness and wear resistance Working hardness: Suitable for materials up to HRc55, enabling machining of hardened steels and high-hardness alloys Chip evacuation: Three-flute geometry promotes effective chip clearance and stable cutting This end mill is engineered to deliver consistent performance where it matters most: tight tolerances, smooth finishes, and long tool life in demanding materials. Its carbide construction provides durability under aggressive milling conditions, while the 3-flute design balances rigidity with efficient chip removal to minimize heat buildup. Ideal for pocketing, slotting, and finishing passes in hardened steels and similar alloys, this tool helps you reduce reworks and improve throughput. When used with appropriate speeds and feeds for carbide tooling, you can expect reliable cuts, minimal deflection, and clean, accurate results across challenging projects.
