ITC Carbide End Mill Corner Radius 4081 - 4 Flute 38° Helix With Roll Relief, Harmonic Fluting, Radius & Coating - Steels & Exotics - 12mm x R0.25

Introducing the ITC Carbide End Mill Corner Radius 4081, a precision cutting tool designed for demanding steels and exotic materials. Featuring a 12 mm cutting diameter and a corner radius of R0.25 mm, this 4-flute end mill combines a 38° helix with roll relief and harmonic fluting to deliver reliable, high-precision performance on complex geometries. The specialized coating further enhances wear resistance, helping you push tougher jobs with confidence.

• Efficient Chip Evacuation and Heat Management: The 38° helix, four flutes, and roll relief work together to promote smooth chip flow, reduce built-up edge, and lower cutting temperatures for steadier machining and consistent results.
• Stable Cutting with Harmonic Fluting: Harmonic fluting minimizes vibration under load, delivering smoother finishes and tighter tolerances on challenging materials and intricate contours.
• Durable Corner Radius and Coating: The precise R0.25 mm radius supports accurate fillets and radii, while the specialized coating resists wear in steels and exotic alloys for longer tool life and dependable performance.

Designed for professionals who demand precision and reliability, this end mill helps you reduce downtime, maintain tight tolerances, and achieve high-quality surface finishes across demanding applications—from pocketing and profiling to finishing complex geometries in hard materials. Trustworthy construction and thoughtful geometry translate to fewer tool changes and more consistent results in your machining workflow.
