Engineered for reliability in confined spaces, the C353 minimizes tool deflection while delivering clean slots and accurate shoulders. The Alcrona Primax coating pairs with a powder-metallurgical HSS-E core to resist wear under high-cutting forces, helping extend tool life and maintain edge stability across repeated passes. The 3-flute design provides a solid balance between rigidity and chip evacuation, making it well-suited for slotting and ramping in a variety of metallic workpieces, including titanium and copper alloys. Ideal for workshops prioritizing consistency, repeatability, and efficient material removal in compact milling operations.
