Description
Widin Carbide Corner Radius End Mill is a precision 12 mm milling cutter designed for demanding CNC work—delivering clean radii, stable cutting, and reliable performance on hardened materials.
- Diameter: 12 mm
- Corner Radius: R0.3
- Flutes: 4
- Material: Solid carbide
- Helix Angle: 45°
- Cutting Style: Corner radius end mill engineered for precise radii and smooth finishing
- Ideal For: Pocketing, contouring, and finishing with exact corner radii
This end mill is engineered for high hardness workpieces, enabling higher feed rates and faster material removal without sacrificing accuracy. The 45° helix supports efficient chip evacuation and stable cuts, which helps reduce chatter and extend tool life during heavy milling of hardened steels and alloys. The four-flute design balances rigidity and chip clearance, making it suitable for pocketing, contouring, and finishing where exact corner radii matter. With its solid carbide construction, you can expect consistent performance across multiple passes and reliable results in challenging applications.
