Description
The ITC Carbide End Mill Corner Radius 5031 is a 16 mm diameter carbide milling tool with a 4 mm corner radius, engineered for high-performance machining in steels and exotic materials. Its 5-flute design uses a variable helix, roll relief, harmonic fluting, and a specialized coating to optimize chip evacuation, reduce cutting forces, and enhance cutting stability for reliable, accurate performances on curved surfaces.
- Efficient chip evacuation and stable cutting: Variable helix, roll relief, and harmonic fluting work together to channel chips away from the cut and minimize vibrations, enabling smoother cuts and higher productivity on challenging materials.
- Durable carbide with advanced coating: Premium carbide combined with a specialized coating delivers long edge life, wear resistance, and consistent performance in steels and exotic alloys, reducing tool changes and downtime.
- Precise 16 mm diameter with R4 corner radius: The 4 mm corner radius provides clean, accurate radii on corners and fillets, expanding capability for complex geometries while maintaining tight tolerances and good surface finish.
Designed for professionals who demand dependable performance, this end mill supports smooth finishes, repeatable results, and efficient workflows across demanding applications. Its combination of geometry, coating, and build quality helps you tackle curved pockets and corners with confidence, delivering reliable results and reducing rework in busy fabrication or machining environments.
