Description
Introducing the ITC Carbide End Mill Corner Radius 4081—a 4 mm diameter carbide end mill with a precise corner radius (R0.25) designed for steels and exotic materials. It features a 4-flute configuration and a 38° helix to promote efficient cutting, clean corners, and reliable chip control in demanding applications.
Built for professionals who require consistent performance in challenging geometries, this tool combines roll relief, harmonic fluting, and a specialized coating to improve cutting stability, reduce cutting forces, and extend tool life. Its robust design delivers reliable results across difficult materials and thin-wall features.
- Efficient Chip Evacuation and Heat Management: The flute geometry and 38° helix optimize chip flow, helping to keep temperatures down and maintain surface quality even in hard materials.
- Corner Radius R0.25 for Precise, Durable Corners: The 0.25 mm corner radius enables accurate, strong corners on complex profiles while harmonic fluting minimizes vibration for smoother cuts and longer tool life.
- Coating and Roll Relief for Extended Tool Life: A specialized coating combined with roll relief reduces wear and friction, delivering reliable performance and longer service intervals in steels and exotic alloys.
This end mill is tailored to improve your workflow: it supports tighter tolerances, cleaner finishes, and fewer reworks on challenging materials. Whether you’re refining intricate geometries or producing repeatable results, the Corner Radius 4081 helps you complete jobs faster with confidence and consistent quality.
