The 3-flute design provides balanced rigidity and efficient chip removal, helping you achieve clean slots and precise shoulders even in smaller work envelopes. The 40° helix and 15° rake optimize cutting action for a smoother finish and reduced tool deflection, while the Alcrona Primax coating lowers wear and heat buildup during sustained cuts. With a precise 12 mm Weldon-style shank and a flat section for secure seating, this DIN 327 D tool maintains accurate alignment across repeated passes. Ideal for free machining steel, stainless steel, and wrought aluminium, it’s a dependable choice when you need consistent slotting, shoulder milling, and ramping in constrained spaces.
