The tool’s 4-flute geometry promotes efficient chip flow and a smooth finish, even in deeper pockets where tool deflection can be a concern. The 45° helix and 12° rake are tuned to deliver predictable plunging and steady ramping, reducing tool wear and improving surface quality on both roughing and finishing passes. Alcrona Primax coating adds wear resistance and heat tolerance, extending tool life in challenging materials. With DIN 844 L designation, this end mill fits standard holders and collet systems, ensuring reliable performance in busy production environments. Its long-series design is ideal for operations that demand reach without compromising rigidity, making it a versatile choice for engineering shops handling mixed material batches.
