The Vortex Carbide Roughing End Mill is a 4-flute, TiSiN-coated cutting tool designed for efficient, high-speed roughing in metalworking. Built for machinists and shops that demand reliability and aggressive material removal, it delivers consistent performance across tough substrates. Flute Count & Geometry: 4-flute standard roughing design for aggressive material removal and smooth chip evacuation. Material: Premium carbide construction for rigidity, wear resistance, and long tool life under heavy cutting. Coating: TiSiN coating reduces friction and heat buildup to extend tool life and maintain cutting stability. Dimensions: 12 mm diameter x 75 mm length, providing versatile reach for standard milling applications. Chip Evacuation: Optimized flute geometry promotes efficient chip removal, minimizing re-cutting and heat buildup. Applications: Ideal for high-speed roughing on steel, stainless steel, cast iron, and high-performance alloys, helping you maximize removal rates. This end mill is built to help you push larger material-removal tasks with confidence. The combination of carbide rigidity, TiSiN coating, and a 4-flute roughing design translates to faster roughing passes, cooler cutting, and longer intervals between tool changes. Use in demanding roughing operations to prepare parts for finishing passes, reduce cycle times, and improve overall machining efficiency on a range of metallic workpieces.
