The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for machinists who demand accurate corners and dependable performance on hard materials. This 4 mm diameter tool delivers clean radii and smooth transitions for reliable pocketing, contouring, and finishing passes.

• Diameter: 4 mm
• Corner Radius: R1.0 (1.0 mm radius) for precise corners and smooth transitions
• Flute Count: 4-flute design for balanced chip evacuation and a quality surface finish
• Length of Cut: 10 mm stub length to maximize rigidity and minimize deflection
• Material: Carbide for wear resistance and longer tool life on tough workpieces
• Shank & Construction: Solid shank design for stable seating in standard collets and holders
• Series: ZR704 family with multiple corner radii sizes and effective lengths to match different features

This end mill delivers reliable, precise milling across a range of hard materials. The carbide construction and stub-length geometry reduce deflection at depth and maintain accurate corner radii, helping you achieve sharp corners or smooth fillets consistently. The 4-flute design combines efficient material removal with a fine surface finish, making it well-suited for pocketing, contouring, and finishing passes in mold making, aerospace components, and automotive parts. With varied corner radii and effective lengths in the ZR704 family, you can tailor tooling to your specific feature sizes and production demands without sacrificing precision or reliability.
