The Widin Carbide Corner Radius End Mill is a compact, high‑precision cutting tool designed for machinists and engineers working with hard materials. With a 3 mm diameter, four-flute stub-cut design, and a precise R0.5 corner radius, it delivers clean pockets and accurate radii in small-tool applications.

• Diameter: 3 mm
• Flute count: 4-flute design for efficient chip evacuation and a smoother finish
• Cutting length / Overall length: Stub-cut length with an overall length of 20 mm for compact, rigid performance in tight pockets
• Corner radius: R0.5 mm, enabling gentle fillets and reduced stress concentration in finished features
• Material: Carbide (cemented carbide) for enhanced hardness capability and wear resistance
• Geometry: Stub-cut end mill geometry that improves rigidity during small-diameter cuts
• Applications: Ideal for machining hard workpieces and tough alloys where precise corners and radii are required
• Construction quality: Designed to maintain accuracy over repetitive cuts with dependable performance in CNC milling

This end mill is purpose-built for precise corner radii and clean side walls on challenging materials. Its four-flute configuration helps balance chip evacuation with a stable cut, reducing deflection and improving surface finish in small features. Use cases include pocketing with rounded corners, finishing fillets, and preparing features that require reliable corner geometry in hardened steels and similar alloys. For best results, pair this tool with appropriate cutting parameters for carbide and monitor tool wear in high-tress environments to maximize life and consistency.
