ITC Carbide End Mill Corner Radius 4081 - 4 Flute 38° Helix With Roll Relief, Harmonic Fluting, Radius & Coating - Steels & Exotics - 16mm x R0.75

The ITC Carbide End Mill Corner Radius 4081 is a high-performance cutting tool designed for precise milling in steels and exotic materials. With a 16 mm cutting diameter and a corner radius of 0.75 mm, this 4-flute end mill combines aggressive chip removal with refined geometry to deliver accurate radii, clean profiles, and reliable finishes across challenging applications. The 38° helix, roll relief, harmonic fluting, and specialized coating work together to boost stability and extend tool life, making it a dependable choice for professional shops and demanding workpieces.

• Efficient chip evacuation and stable cutting: The 4-flute design and optimized flute geometry promote smooth chip flow and consistent cutting forces, reducing vibration and improving surface finish on hard materials.
• Harmonic fluting with roll relief: Precision flute design minimizes chatter and tool deflection, delivering smoother operation, tighter tolerances, and longer tool life in tough steels and exotic alloys.
• Corner radius + durable coating: The 0.75 mm radius maintains accurate internal and external curves, while the specialized coating enhances wear resistance for extended tool life in demanding environments.

Designed for engineers, machinists, and skilled technicians, this end mill helps you achieve repeatable radii and consistent results across parts and batches. It supports faster setup, fewer rework cycles, and reduced downtime, enabling you to hit tighter tolerances with confidence while maintaining a smooth workflow from roughing to finishing.
