The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for engineers and machinists who demand reliability and versatility. This 4-flute stub-cut end mill (Ø4 mm, LOC 16 mm, R0.5) balances rigidity with precise geometry for pockets, slots, and contouring tasks.

• Diameter: 4 mm
• Cutting length: 16 mm (stub-cut) for compact, rigid cutting
• Flute count: 4-flute geometry to improve material removal and edge finish
• Corner radius: R0.5 mm for precise internal and external radii
• Material: Solid carbide for hardness and wear resistance
• Series: ZR704 with extended corner radius options to suit multiple applications
• Design: Stub-cut length enhances rigidity and reduces deflection in shallow pockets

With its carbide construction and optimized geometry, this end mill helps you achieve accurate corners, smooth radii, and reliable tool life across challenging materials. The 4-flute design enables efficient chip evacuation, reducing heat build-up and minimizing chatter. The R0.5 mm corner radius offers flexibility: you can produce sharp transitions when needed or introduce gentle radii to reduce stress concentrators, improving part durability. The compact stub-cut length provides rigidity for precise milling in shallow features, improving dimensional accuracy and surface finish. This tool is ideal for pocketing, contouring, and finishing operations where precision and control matter. For best results, start with light break-in passes, maintain steady feeds and speeds suited to the material, and use appropriate clamping and coolant to extend tool life and achieve consistent finishes.
