The Vortex VOR45-CCRC-0.40 carbide corner rounding cutter delivers precise external radii with a robust, high-performance build—perfect for machinists and manufacturing teams that demand clean, repeatable fillets on a variety of materials. Material: Solid carbide construction for rigidity, heat resistance, and long tool life Coating: TiAlN coating to boost wear resistance and performance at higher speeds Radius: External corner radius of R0.40 mm for accurate fillets on workpieces Diameter: 3 mm cutting diameter for compact, precise machining in tight spaces Flute configuration: 2- or 4-flute design within the VOR45-CCRC family to balance finish quality and chip evacuation Applications: Ideal for external radii on steel, stainless steel, cast iron, copper, and aluminium This cutter is designed to produce smooth, consistent corners, reducing the need for secondary finishing and helping parts meet tight tolerance requirements. The TiAlN coating extends tool life by reducing wear under high-speed cutting, while the carbide core maintains rigidity for reliable performance across a range of alloys. Its compact 3 mm diameter with a precise R0.40 mm radius makes it well-suited for small-geometry radii on intricate components, from brackets and housings to fixtures and enclosures.
