The Widin Carbide Corner Radius End Mill is a precision tool purpose-built for mold and die work, delivering clean corners and smooth surfaces in tight, intricate features. With a 0.3 mm diameter and a long-neck design, it’s engineered for deep cavities and detailed micro-milling tasks.

• Diameter: 0.3 mm
• Corner Radius: R0.02 (0.02 mm)
• Flutes: 2
• Helix Angle: 30°
• Shank Design: Long neck for extended reach
• Material: Carbide
• Application: Mold & die milling, precision micro-milling

This end mill is built to handle delicate mold features and deep grooves without sacrificing rigidity. The 2-flute configuration balances material removal with surface finish, helping maintain stable cuts in small-diameter work. The 30° helix angle promotes efficient chip evacuation and reduces cutting forces, contributing to higher productivity and cleaner finishes. The 0.02 mm corner radius minimizes stress concentrations at corners, improving tool life when profiling sharp yet resilient mold surfaces. Its long-neck design provides the reach needed for deep pockets and undercuts common in complex mold and die components, while preserving accuracy and stability throughout the machining process.
