Widin’s 20 mm carbide end mill is engineered for stainless steels and exotic alloys. This 4-flute tool uses a double-core design to boost rigidity and anti-bending strength, helpin g you cut with confidence even under heavy loads. Combined with unequal index flutes and a variable-helix profile, it delivers efficient chip evacuation and a smooth surface finish on tougher materials. Ideal for machinists, engineers, and workshops working with challenging materials, this end mill starts cleanly and maintains stability through deep pockets and aggressive passes. The chamfered edge on the end face further reduces cutting edge chipping during entry and finishing passes, extending tool life and reducing rework. Double-core carbide construction: Anti-bending strength and rigidity that keep cuts stable and extend tool life on stainless and exotic materials. Unequal-index 4-flute geometry with variable helix: Optimizes chip evacuation and reduces vibration for a smoother surface finish and consistent cuts. Chamfered end face: Minimizes edge chipping on entry and finishing passes for longer tool life and more reliable starts. By combining robust carbide, precise geometry, and protective chamfering, this end mill helps you complete precision work faster with less tool wear and fewer passes. It delivers stable cuts, predictable finishes, and durable performance in demanding milling tasks, making it a reliable choice for any shop aiming for efficiency and quality. Show more
