ITC Carbide End Mill Corner Radius 2161 - 2 Flute 45° Helix With Facet Relief & Radius - Non-Ferrous - 20mm x R4

Introducing the ITC Carbide End Mill Corner Radius 2161—a high-performance tool engineered for non-ferrous machining. With a 20 mm diameter, a 4 mm corner radius (R4), a 2-flute design, and a 45° helix, it delivers efficient chip evacuation and stable, precise cuts for reliable results on aluminum, copper, brass, and other non-ferrous materials.

• Efficient chip evacuation with 45° helix: The 45° helix and optimized flute geometry promote fast chip removal, reduce built-up edge, and help maintain steady cutting at speed.
• Precise corner radius for non-ferrous parts: The 4 mm corner radius creates sharp, repeatable features on aluminum, copper, brass, and other non-ferrous materials, supporting tight tolerances and clean edges.
• Facet relief for smoother cuts and longer tool life: The facet relief reduces rubbing and cutting forces, improving surface finish and extending tool life in demanding non-ferrous applications.

Designed to speed setup, reduce downtime, and deliver repeatable results, the ITC Corner Radius 2161 supports accurate profiles and smooth finishes across non-ferrous workpieces. Its carbide construction and optimized geometry stand up to busy shop environments, helping you meet tight tolerances with confidence and minimize rework across both prototype runs and ongoing production.
