Widin Carbide End Mill for Stainless & Exotics, 16 mm, is a precision cutting tool designed for demanding metals. It uses a 3-flute double-core geometry with a variable helix and a chamfered end face to promote excellent chip emission and deliver a smooth, consistent surface finish on stainless steel and exotic alloys. Unequal index flutes for efficient chip emission: The varied flute spacing helps chips evacuate quickly, reducing built‑up edge and delivering a cleaner finish on hard-to-cut materials. Double core for anti-bending strength: Dual-core construction increases rigidity, improving stability during heavy cuts and helping resist deflection when machining tough alloys. Chamfered end face to reduce edge chipping: The chamfered cutting edge minimizes edge damage at the tip, extending tool life and maintaining consistent performance on challenging materials. This carbide end mill is built for reliable, repeatable results in stainless and exotic materials. Its proven geometry and durable construction help you achieve steady cuts, smooth finishes, and fewer rework passes, making it a dependable choice for professional shops and serious hobbyists alike.
