ITC Carbide End Mill Corner Radius 2161 - 2 Flute 45° Helix With Facet Relief & Radius - Non-Ferrous - 20mm x R0.25

The ITC Carbide End Mill Corner Radius 2161 is a high-performance cutting tool engineered for non-ferrous metals like aluminum, brass, and copper. It features a 20 mm diameter with a precise R0.25 corner radius and a 2-flute design, paired with a 45° helix to deliver efficient chip evacuation and stable cutting. The addition of facet relief helps reduce rubbing and heat buildup, resulting in clean edges and accurate corner radii right from the first pass.

Designed for professionals who demand reliability and consistent results, this carbide end mill is built to withstand demanding machining environments. Its geometry supports smooth operation, long wear life, and dependable performance across multiple production cycles.

• Specialized for non-ferrous metals: Optimized geometry minimizes built-up edge and delivers clean surface finishes on aluminum, brass, and similar alloys, reducing finishing steps and rework.
• 2-flute design with 45° helix: Fewer flutes enable efficient chip clearance in soft metals, while the 45° helix provides strong cutting action with reduced vibration for steadier, faster material removal.
• Corner radius with facet relief: The R0.25 corner radius combines durability with precision; facet relief reduces edge rubbing and heat, extending tool life and delivering consistently sharp corners.

This combination of carbide hardness, optimized geometry, and precise radii helps you complete parts faster, achieve tighter tolerances, and keep production moving with minimal downtime. Whether you’re setting up a new aluminum project or sustaining high-volume non-ferrous milling, the 2161 end mill is designed to deliver reliable results with every cut.
