This tool excels in copy milling and finishing complex contours, delivering consistent wall geometry and smooth surface finishes in pockets and slots. The 7 mm radius supports gentle entry into curved paths, reducing chatter and improving dimensional accuracy. The cobalt-based HSS-E construction provides enhanced wear resistance and durability for longer tool life in challenging materials. The flatted Weldon shank and solid overall geometry promote reliable grip and rigidity, helping you maintain precision across deeper cavities and extended reach.
