Widin Carbide Corner Radius End Mill for Aluminium & Non-Ferrous is a high-precision cutting tool designed for contouring and finishing soft metals. With a 20 mm diameter and a 5.0 mm corner radius (R5.0), this 3-flute end mill features a 45° helix that delivers clean radii and steady cutting performance on aluminum and other non-ferrous alloys.

• Diameter and corner radius: 20 mm diameter with a 5.0 mm corner radius (R5.0) for durable edges and smooth fillets
• Flute count: 3-flute design balances material removal with finish quality
• Helix angle: 45° helix for efficient chip evacuation and stable cutting in soft metals
• Material: Premium carbide construction provides hardness, wear resistance, and long tool life
• Chip evacuation: Optimized flute geometry supports quick swarf removal and reduced clogging
• Applications: Specifically optimized for aluminium and non-ferrous materials, ideal for contouring, pocketing, and finishing

In practical use, this end mill delivers smooth contouring with less edge chipping thanks to the R5.0 corner radius, while the 3-flute design maintains a strong material removal rate without sacrificing surface finish. The carbide composition ensures durability under typical aluminum machining conditions, and the 45° helix promotes consistent cutting pressure and efficient chip clearance. Use it for precise radii, clean pockets, and refined edges on thin-walled parts or complex profiles where accuracy and finish matter.
