With its ball-nose geometry, this end mill excels at producing accurate curves, fillets, and complex surfaces while delivering clean, repeatable finishes on copper alloys and free-machining steels. The 30° helix promotes efficient chip evacuation and steady cutting forces, helping to minimize vibration in tight pockets. The 12° rake angle further stabilizes cutting action, enhancing surface quality in delicate profiles. The cobalt-enhanced HSS-E core provides added wear resistance for longer tool life in demanding materials, while the bright finish reduces built-up edge in copper workpieces. The DIN 327 D specification ensures compatibility with standard holders and collets for reliable mounting in CNC machines.
