Designed with an asymmetrical fine-pitch profile for efficient chip formation and tool life, this end mill maintains rigidity and precision during aggressive roughing. The powder-metallurgical HSS-E base combined with the Alcrona Primax coating reduces wear and friction, helping to sustain cutting performance over longer runs. The 25 mm Weldon shank offers solid clamping compatibility with standard tool holders, while the 64.5 mm neck relief minimizes interference in tight pockets and complex operations. This makes the C428 a dependable choice for operators seeking predictable results in challenging materials.
