The Europa Tools Corner Rounding Cutter is a precision end mill designed to deliver clean, repeatable 3.0 mm radii on metal parts. With a 12 mm diameter and a robust 4-flute HSS-E cobalt construction, it’s built for consistent edge rounding in demanding machining environments. Size & Radius: 12 mm diameter with a 3.0 mm corner radius (R3.0) for precise, uniform rounding. Material: HSS-E cobalt composition enhances hardness and heat resistance for tougher materials and higher-speed machining. Flute Count: 4-flute design improves chip evacuation and delivers smoother cuts with better finish. Durability: Hard-wearing construction maintains edge quality under higher cutting speeds and longer tool life. Applications: Suitable for steel, stainless steel, and non-ferrous metals, ideal for creating smooth, safe edges on brackets, housings, and similar components. This cutter solves the common edge-finishing challenge by producing a reliable, consistent corner radius that eliminates sharp edges and reduces post-processing. The 4-flute geometry, combined with cobalt-enhanced steel, supports efficient material removal, smoother surface finishes, and repeatable radii across multiple parts. Ideal for fabrication and machining workflows where precision corners and burr-free edges are essential, it helps you achieve professional-grade results with fewer finishing passes.
