Widin Carbide Corner Radius End Mill is a precision cutting tool designed for stainless steel and exotic materials. With a 3 mm diameter and a 0.3 mm corner radius, this 4-flute end mill is ideal for pocketing, profiling, and finishing where a gentle rounded edge and clean walls are required.

It’s built for both professionals and dedicated hobbyists who value reliability and consistent results. The combination of robust carbide construction and a smart flute design helps you achieve smooth workpiece surfaces while delivering dependable performance across challenging materials.

• Unequal index flutes for efficient chip evacuation: The staggered flute spacing promotes quick chip removal, reducing clogging and yielding a smoother surface finish on stainless and exotic alloys.
• Wear-resistant carbide with a sharp cutting edge: High-hardness carbide and a durable edge provide excellent wear resistance, helping the tool stay sharp longer in tough materials and extend tool life.
• Versatile corner radii for flexible finishing: Available with various corner radius sizes to match part geometry, enabling precise corner treatment and reducing the need for rework or secondary operations.

This end mill is designed to deliver consistent, precise pockets and smooth wall finishes in demanding stainless and exotic applications. The 4-flute, variable-helix geometry helps stabilize cutting, manage heat, and produce reliable results across a range of feeds and speeds, making it a trustworthy choice for projects that demand quality and efficiency.
