ITC Carbide End Mill Square Edge 7N22 - 2 Flute 30° Helix With Facet Relief & Coating - Micro - 2.5mm

The ITC Carbide End Mill Square Edge 7N22 is a high-precision micro end mill with a 2.5 mm diameter, engineered for intricate detail work in micro-machining. Its compact two-flute design and 30° helix are optimized to deliver clean cuts and reliable performance on small features, making it ideal for engineers, machinists, and hobbyists tackling tight tolerances and delicate materials.

Featuring facet relief and a specialized coating, this tool improves chip evacuation, reduces cutting forces, and enhances cutting stability across a range of micro applications. The result is smoother finishes, more predictable results, and longer tool life in demanding micro-machining tasks.

• 2-Flute micro-cut geometry: Designed for precise material removal at small diameters, the two flutes provide efficient chip evacuation and stable cutting for fine features, helping to minimize heat buildup and improve surface finish.
• 30° helix with facet relief: The angled cut and facet relief promote a smooth shearing action, excellent chip flow, and reduced cutting forces, delivering consistent performance in tight tolerances and challenging materials.
• Coated carbide for durability: A specialized coating enhances wear resistance and heat management, extending tool life and maintaining stable performance across multiple passes.

In practice, this end mill helps you achieve precise dimensions on micro features with repeatable results, while improving workflow by reducing tool changes and downtime due to wear or chip buildup. The rugged carbide core, combined with thoughtful geometry and coating, delivers reliable, high-quality finishes for demanding micro-machining projects.
