Widin Carbide Corner Radius End Mill for stainless steel and exotic alloys offers a precise 12 mm cutting diameter with a 0.5 mm corner radius, built as a 3-flute tool with a double-core design and a variable helix. Designed for engineers, fabricators, hobbyists, and professionals alike, this end mill delivers clean internal radii, reliable performance, and smooth surface finishes in challenging materials.

• Unequal index flutes for improved chip evacuation: The staggered flute arrangement helps chips exit efficiently, reducing heat buildup and promoting a smoother, consistent finish on stainless and exotic metals.
• Double-core construction for anti-bending strength: A reinforced core design increases rigidity, minimizing deflection under load and extending tool life in tough cutting conditions.
• Variable-helix, 3-flute geometry for versatile cutting: The variable angle reduces chatter and provides stable cutting across different feeds and depths, delivering reliable results in a range of applications.

This end mill supports efficient workflows by combining robust carbide hardness with smart geometry, helping you achieve precise radii and high-quality surface finishes with fewer passes. Its durable construction and chip-control design mean fewer tool changes and more consistent results, whether you’re machining stainless parts, exotic alloys, or similar demanding materials.
