ITC Carbide End Mill Corner Radius 2161 - 2 Flute 45° Helix With Facet Relief & Radius - Non-Ferrous - 20mm x R5

Introducing the ITC Carbide End Mill Corner Radius 2161, engineered for high-performance machining in non-ferrous materials. This 20 mm diameter tool features a 5 mm corner radius and a 2-flute design with a 45° helix, plus facet relief and an integrated radius to deliver precise corners and efficient chip flow. Built for professionals who value accuracy and reliability in every cut, it excels on aluminum, copper, brass, and other non-ferrous alloys.

In use, this end mill maintains stability and control across demanding operations, helping you achieve consistent dimensions and clean finishes with fewer passes. The carbide construction provides sharp, durable cutting edges that resist wear while maintaining edge geometry through extended tool life.

• 2-Flute Design for Efficient Cutting: Lower tooth load promotes fast chip evacuation and smooth, stable cutting in non-ferrous materials, helping maintain surface finish and reduce heat buildup.
• 45° Helix with Facet Relief and Radius: Optimized geometry reduces cutting forces, enhances rigidity, and delivers consistent corner radii for precise parts and better finish quality.
• Built-In R5 Corner Radius for Precise Edges: The precise 5 mm corner radius ensures repeatable, accurate corners, enabling reliable fits and reduces the need for secondary finishing steps.

By delivering reliable corner radii and smooth chip evacuation, the ITC 2161 helps you reduce finishing time, boost workflow efficiency, and improve overall part quality in non-ferrous milling. Its robust carbide construction and thoughtful geometry provide dependable performance across production runs and prototype work alike, making it a trusted choice for engineers, machinists, and hobbyists who demand consistent results.
