Engineered for precision radius work, the Vortex VOR45-CCRC 3 mm carbide corner rounding cutter with TiAlN coating is built for machinists and fabricators who need clean, consistent external radii across a variety of materials. Solid carbide construction: rigid, durable cutting edge that maintains tight radius tolerances during external radius machining. TiAlN coating: high-temperature wear resistance that supports higher cutting speeds and longer tool life in demanding applications. 3 mm diameter with R0.25 corner radius: precise small-radius tool well-suited for fine edge rounding and detail work on profiles. 2- and 4-flute configurations: flexible geometry for balanced finish quality and efficient chip evacuation across different depths of cut. External radius specialization: specifically designed to form smooth, accurate outside corners, reducing the need for secondary finishing. Material versatility: excellent performance on Steel, Stainless Steel, Cast Iron, Copper and Aluminium, making it a reliable choice for mixed-material projects. This cutter delivers reliable radius control for brackets, enclosures, housings, and other parts where a clean, reproducible corner is essential. The TiAlN-coated carbide edge stands up to higher-speed machining and tougher materials, helping you shorten cycle times while keeping edge quality consistent. Whether you’re finishing a series of parts or tackling a prototyping run, this tool provides predictable results and reduced finishing workload.
