ITC Carbide End Mill Corner Radius 5021 - 5 Flute Variable Helix With Roll Relief, Harmonic Fluting, Radius & Coating - Steels & Exotics - 12mm x R2.5

The ITC Carbide End Mill Corner Radius 5021 is a 12 mm diameter carbide tool with a 2.5 mm corner radius (R2.5), engineered for precision machining in steels and exotic materials. Its 5-flute, variable-helix design, combined with roll relief and harmonic fluting, delivers smooth cutting, stable contouring, and reliable performance on complex features. A specialized coating enhances wear resistance, helping you achieve clean finishes at higher productivity.

• 5‑Flute Variable Helix for Smooth, Stable Cuts: The varied flute spacing reduces vibration and promotes efficient chip evacuation, enabling consistent finishes even in demanding steels and exotic alloys.
• Roll Relief and Harmonic Fluting for Reduced Cutting Forces: Roll relief lowers contact pressure while harmonic fluting dampens chatter, extending tool life and maintaining precision through tough runs.
• Corner Radius with Durable Coating for Precision Contours: The R2.5 corner radius supports accurate fillets and contour features, and the coating boosts wear resistance for reliable performance over time.

This end mill helps you streamline workflows by delivering reliable geometry and extended tool life, reducing downtime from tool changes and rework. Its durable construction and optimized cutting mechanics translate to improved surface finishes, higher material removal rates, and greater confidence when machining hard steels and exotic materials across complex geometries.
