ITC Carbide End Mill Corner Radius 4081 - 4 Flute 38° Helix With Roll Relief, Harmonic Fluting, Radius & Coating - Steels & Exotics - 6mm x R2

The ITC Carbide End Mill Corner Radius 4081 is a precision cutting tool designed for challenging steels and exotic materials. With a 6 mm diameter and a 2 mm corner radius (R2), this 4-flute end mill combines a 38° helix, roll relief, harmonic fluting, and a specialized coating to deliver consistent, high-quality results. Built for professionals who demand reliability, stability, and long tool life, it excels in complex geometries and tough workpieces.

Whether you’re a shop floor engineer, a skilled machinist, or a hobbyist tackling demanding materials, this end mill is designed to stay productive under tough conditions—reducing chatter, improving surface finish, and delivering dependable performance across steels and exotic alloys.

• Efficient chip evacuation with roll relief: The roll relief and harmonic fluting channel chips away from the cutting edge, reducing heat buildup and extending tool life in hard-to-machine materials.
• 38° helix for smooth, stable cuts: The steep helix provides strong penetration and effective chip removal, delivering consistent finishes even at higher feed rates.
• Durable radius geometry and coating: The 2 mm corner radius maintains precise profiles in corners and pockets, while a specialized coating boosts wear resistance and overall tool longevity.

This combination helps you finish parts faster with fewer tool changes, reduces downtime from tool wear, and delivers reliable, repeatable results you can trust for tight tolerances and high-precision machining.
