The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for machinists and shops that regularly work with hard materials. It features a 4 mm diameter and a 0.3 mm corner radius, delivering clean pockets, smooth edges, and reliable performance across tough metals.

• Diameter: 4 mm
• Corner Radius: R0.3 (0.3 mm) for smooth, precise corners
• Flute Count: 4-flute design for efficient chip evacuation and stable cutting
• Material: Solid carbide for high hardness workpieces and extended tool life
• Helix Angle: 45° to enable high-speed cutting with good rigidity and chip clearance

This end mill is designed to maximize material removal while preserving workpiece finish. The 45° helix and 4-flute geometry reduce cutting forces and improve stability at higher feeds, helping to minimize dwell time and keep tolerances tight on pockets, slots, and contours. The carbide construction resists wear, enabling longer intervals between tool changes and lower maintenance costs. Whether machining hardened steels or intricate profiles, this end mill delivers consistent results and predictable performance.
