Description
The ITC Carbide End Mill Corner Radius 4081 is a high-performance milling tool designed for steels and exotic materials. It features a 4 mm diameter with a 0.5 mm corner radius, delivering precise, clean corners and smooth transitions on complex parts.
Designed for professionals who demand consistent results, this 4‑flute end mill combines a 38° helix, roll relief, harmonic fluting, a radius, and a specialized coating to optimize chip evacuation, reduce cutting forces, improve stability, and extend tool life under challenging applications.
- Corner Radius for Smooth, Accurate Corners: Delivers a precise 0.5 mm radius that preserves edge geometry, reduces stress concentrations, and helps achieve smooth, consistent finishes on steels and exotic alloys.
- 38° Helix with Roll Relief and Harmonic Fluting: The combination minimizes vibration and cutting forces, enabling stable engagement, cleaner chip evacuation, and longer tool life on tough materials.
- Durable Coating and Geometry for Longevity: Enhanced wear resistance and heat tolerance, paired with optimized geometry, deliver reliable performance across multiple passes, reducing tool changes and rework.
With the ITC 4081, you gain a reliable, precise end mill that supports high-quality finishes and predictable results—from roughing through finishing—in steels and exotic materials. The 4‑flute design, optimized helix, and protective coating work together to maintain stability, control chips, and extend tool life, helping you improve throughput, reduce downtime, and achieve consistent production outcomes.
