The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for aluminum and non-ferrous metals. With a 20 mm diameter, 4.0 mm corner radius (R4.0), 3 flutes, and a 45° helix, it delivers clean contours and reliable performance on challenging profiles.

• Diameter: 20 mm
• Corner Radius: R4.0 (4.0 mm) for smooth transitions and reduced chipping
• Flute Count: 3 flutes for balanced rigidity and effective chip control
• Helix Angle: 45° for efficient cutting in aluminum and non-ferrous alloys
• Material: Solid carbide construction for wear resistance and long tool life
• Material Compatibility: Optimized for aluminum and other non-ferrous metals
• Chip Evacuation: Flute geometry designed to evacuate chips quickly, maintaining cool cutting conditions
• Finish Quality: Delivers smooth contours and accurate edges

The combination of a 3-flute design and a 45° helix enhances cutting performance by delivering steady material removal and efficient chip evacuation. The corner radius supports smooth contouring and reduces the risk of edge chipping, while the carbide construction provides durability for repeated passes. This end mill excels in profiling, pocketing, and deburring tasks on aluminum and non-ferrous parts, helping you achieve consistent surface finishes and precise radii across jobs such as mold components, enclosures, and lightweight assemblies.
