Widin Carbide Corner Radius End Mill - 4 Flute - 12mm x R2.0

The Widin Carbide Corner Radius End Mill is a high‑performance cutting tool designed for precise contouring in hard‑to‑machine materials. With a 12 mm diameter and a 2.0 mm corner radius, this 4‑flute carbide end mill delivers reliable finishes on demanding profiles.

• Diameter: 12 mm
• Corner Radius: R2.0 (2.0 mm) for smooth internal corners and fillets
• Flutes: 4‑flute geometry provides rigid cutting and efficient chip evacuation
• Material: Solid carbide for hardness, wear resistance, and long tool life
• Helix Angle: 45° helix enables high‑speed cutting while maintaining stability
• Application: Optimized for machining hard materials and intricate pocketing/contouring tasks

This end mill is tailored for high hardness workpieces, delivering consistent performance and reduced downtime. The combination of carbide hardness, a robust 4‑flute design, and a 45° helix supports higher feeds and smoother finishes, making it well suited for precision mold/die work, aerospace components, and automotive parts where accurate radii and clean corners matter.

For corner radii and radiused profiles, using a tool with an appropriate radius helps preserve edge integrity and extend tool life by reducing chipping and edge wear. The 45° helix further aids chip evacuation and steady cutting at elevated speeds, contributing to a reliable surface finish. These principles are widely recognized in corner‑radius end mills and are reflected in Widin’s approach to high‑performance milling tools.
