The Widin Carbide Corner Radius End Mill is a precision micro-milling tool designed for machinists and hobbyists who need clean corners and reliable radii on hard materials. Built to deliver consistency in tight pockets and fine features, it’s optimized for demanding machining tasks where accuracy matters.

• Diameter: 1 mm
• Corner radius: R0.3 mm
• Flutes: 4
• Cutting length: Stub length
• Shank diameter: 4 mm
• Material: Solid carbide
• End mill type: Center-cut for versatile pocketing, profiling, and finishing
• Application: Designed for high-hardness workpieces and precision interior corners

This end mill combines a compact 1 mm cutting diameter with a robust 4-flute geometry to resist deflection and maintain sharp corners at small scales. The carbide construction delivers sustained hardness and wear resistance, enabling consistent performance across repeated passes in hard materials such as stainless steel and hardened steels. The 4 mm shank enhances rigidity when mounted in standard collet systems, helping minimize vibration and deliver smoother finishes.
