S521 4-flute milling cutters have a 45 degree helix for high performance profiling on CNC machines and a short flute design with corner radius, great for standard profile milling where a fillet radius is required. They have a titanium silicon nitride coating for increased tool life and improved performance when milling difficult to machine materials. Manufactured from premium carbide for great performance and longer tool life, S521 corner radius milling cutters are designed specifically for high speed machining in hardened tool steels up to 63HRC.
