ITC Carbide End Mill Corner Radius 2161 - 2 Flute 45° Helix With Facet Relief & Radius - Non-Ferrous - 12mm x R0.75

The ITC Carbide End Mill Corner Radius 2161 is a high-performance cutting tool designed for non-ferrous machining. With a 12 mm cutting diameter and a 0.75 mm corner radius (R0.75), this two-flute end mill pairs a 45° helix with facet relief to deliver precise radii and stable cuts. Built for professionals who value accuracy and reliability, it excels when working with aluminum, brass, copper, and other non-ferrous materials.

Thanks to its optimized geometry, this end mill promotes efficient chip evacuation and smooth cutting, helping you achieve consistent finishes and predictable tool life across demanding contouring and pocketing tasks.

• Precise corner radius for repeatable part geometry: The R0.75 corner radius provides consistent, filleted corners across passes, reducing the need for secondary finishing and delivering reliable, repeatable results.
• 2-flute design with 45° helix and facet relief: This geometry enhances chip evacuation, minimizes cutting forces, reduces vibration, and supports stable cuts in tight radii and deep pockets for cleaner surfaces.
• Rugged carbide tool optimized for non-ferrous materials: Constructed from carbide for long tool life and reliable performance when cutting aluminum, brass, and copper, with a 12 mm diameter setup providing stiffness and reduced deflection in demanding work.

For buyers and operators, the 2161 helps you improve throughput and finish quality. The combination of radius, helix angle, and facet relief translates to fewer passes, less deburring, and more consistent results across batches. The 12 mm diameter adds rigidity in pocketing and contouring, reducing tool deflection and improving dimensional accuracy, ultimately saving time and boosting productivity in everyday non-ferrous machining.
