Widin Carbide End Mill for Stainless & Exotics, 4 mm diameter, 3 flutes with a double-core design and a variable helix, finished with a chamfered end face. This tool is engineered for stainless steels and exotic alloys, delivering smooth surface finishes and dependable chip control through unequal index flutes that promote efficient chip emission. Unequal index flutes for smooth finishes: Optimized flute spacing improves chip evacuation and helps produce a cleaner, smoother surface on stainless and exotic materials. Double-core construction for higher rigidity: Enhanced anti-bending strength reduces deflection under load, delivering consistent, accurate cuts even in tough alloys. Chamfered end face to reduce edge chipping: The chamfered edge minimizes cutting-edge damage during entry and heavy cuts, extending tool life and maintaining performance. This end mill supports reliable, repeatable results across demanding machining tasks. By combining efficient chip control, added rigidity, and edge protection, it helps you maintain tight tolerances, improve surface quality, and reduce downtime—so parts finish cleaner, faster, and with greater confidence.
