Widin Carbide Corner Radius End Mill is a precision cutting tool designed for machinists and shops tackling hard materials. The 4-flute, stub-cut geometry delivers rigidity and reliable radii, making it ideal for precision corners, chamfers, and smooth profiles across a variety of projects.

• Size: 4 mm diameter x 16 mm overall length
• Corner Radius: R0.3
• Flutes: 4-flute design for stable rigidity and efficient chip evacuation
• Cutting Length: Stub-cut length to minimize deflection and maximize stiffness
• Material: Carbide for exceptional hardness retention and wear resistance
• Design: ZR704 platform for extended corner radius options and flexible effective lengths

This end mill is engineered to perform consistently on high-hardness workpieces, delivering precise corners or smooth radii with minimal finishing work. The stub-cut geometry reduces tool deflection at higher feeds, enabling cleaner cuts, better surface finish, and tighter tolerances. Carbide construction provides long tool life and reliable performance across a range of CNC machines, making it a dependable choice for mold making, automotive components, and precision engineering tasks that demand repeatable results.
