The Widin Carbide Corner Radius End Mill is a precision cutting tool built for hard materials, offering reliable radii and crisp corners in a compact 4‑flute, stub-cut design. Designed for professionals who need consistent performance in demanding machining tasks, this end mill features a 4 mm diameter, 12 mm cutting length, and a 0.3 mm corner radius to handle precise contouring with confidence.

• Diameter and cutting length: Ø4 mm cutting diameter with a 12 mm length of cut (stub-cut) for rigidity in tight features and controlled depth of cut.
• Corner Radius: R0.3 mm corner radius enables precise corner definition or smooth radii in contouring tasks.
• Flute configuration: 4-flute design balances efficient material removal with a clean finish on hard materials.
• Material: Carbide construction delivers high hardness performance and longer tool life in demanding workpieces.
• Series and geometry: Part of the ZR704 family, which offers extended neck lengths and multiple corner-radius options for flexible machining.

This end mill is well-suited for pockets, contours and features where a defined corner or a gentle radius is essential. The stub-cut length enhances rigidity for precise plunging and stable cutting in hard steels and other challenging materials, while the 4-flute geometry maintains steady chip evacuation and smooth surface finishes. Its design supports accurate radii control, making it a dependable choice for detail work, deburring, and finishing applications that demand repeatable geometry.
