Widin’s carbide corner radius end mill is built for mold and die work, delivering precise corners and smooth surfaces with a compact 3 mm diameter. This 2-flute cutter features a long-neck design for extended reach, making it ideal for deep pockets and intricate cavity work.

• Diameter: 3 mm
• Overall length: 16 mm
• Corner radius: R1 (rounded corner to improve fillets and reduce stress concentrations)
• Flutes: 2
• Helix angle: 30° for efficient material removal and stable cutting
• Shank/neck: Long-neck design provides extended reach and rigidity for deep grooves
• Material: Carbide for enhanced hardness and wear resistance
• Application: Optimized for mold and die machining, pocket finishing, and precise corner radii

This end mill combines a two-flute geometry with a 30° helix to deliver clean finishes and predictable chip evacuation across a range of mold and die materials. The long-neck (extended reach) design enables access to deep features without additional setups, while the R1 corner radius offers durable, smooth transitions in corners. Ideal for achieving consistent surface quality and accurate fillets in cavity work, cores, and detailed channel geometries.
