Features a fine-grain diamond-polished cutting edge, which improves surface finish and achieves a surface roughness of ISO N4 for machined parts. Innovative iridescent coating, particularly suitable for machining non-ferrous metals such as copper and aluminum, as well as plastics; it is also ideal for machining steel parts with high aesthetic requirements. The low coefficient of friction eliminates tool sticking and breakage during the machining of aluminum and plastic parts. Unevenly spaced U-shaped grooves provide anti-vibration design; this increases chip evacuation space and improves metal removal rates; both face milling and side milling achieve a high-gloss finish.
