Meet the WidIn Carbide Corner Radius End Mill—designed for mold and die applications that demand precise corner radii and reliable reach. With a 4 mm diameter, 45 mm overall length, and a long-neck design, it delivers smooth finishes in tight, deep cavities.

• Diameter: 4 mm
• Overall length: 45 mm
• Neck type: Long neck for extended reach into deep profiles
• Flutes: 2
• Corner radius: R0.2
• Helix angle: 30°
• Material: Carbide for hardness and edge retention
• Shank: Long shank design stabilizes cuts in deep grooves
• Application: Mold and die machining

The combination of a two-flute geometry and a 30° helix provides efficient material removal with reduced cutting forces, enabling smoother surface finishes and better processability in mold cavities. The long-neck design gives you the extended reach needed for deep grooves and tight features often found in molds and dies, while the R0.2 corner radius preserves part geometry and minimizes stress concentrations. Carbide construction ensures wear resistance and consistent performance over time, helping you maintain tight tolerances and repeatable results.
