Meet the Widin Carbide Corner Radius End Mill — a precision cutting tool designed for aluminum and other non-ferrous metals. With a 20 mm diameter, a 4.0 mm corner radius, and a 2‑flute, 45° helix geometry, it delivers efficient material removal and reliable performance in a range of milling tasks.

• Diameter: 20 mm
• Corner Radius: R4.0 (4.0 mm)
• Flute Count: 2 flutes
• Helix Angle: 45°
• Material: Carbide
• Applications: Suitable for aluminium and non-ferrous milling
• Cutting Type: End mill

This end mill geometry is optimized to clear chips quickly and maintain steady cutting forces, which helps prevent vibration and deflection during milling. The corner radius strengthens the tip, reducing the risk of chipping or breakage at higher speeds and feeds. The 45° helix improves chip evacuation and contributes to a cleaner cut and better surface finish on soft metals. Ideal for pocketing, contouring, deburring, and light finishing work in prototyping, fixture work, and small to medium production settings.
