ITC Carbide End Mill Corner Radius 2161 - 2 Flute 45° Helix With Facet Relief & Radius - Non-Ferrous - 5mm x R0.25

The ITC Carbide End Mill Corner Radius 2161 is a precision cutting tool built for high-performance machining in non-ferrous materials. With a 5 mm diameter and a 0.25 mm corner radius, this 2-flute end mill combines a 45° helix with facet relief to deliver clean corners, efficient chip evacuation, and steady cutting action. It’s ideal for professionals who require accurate radii and reliable results across aluminum, copper, and similar alloys.

Whether you’re setting up a new CNC program or finishing a detailed profile, this end mill’s geometry emphasizes stability and durability. The 45° helix accelerates material removal while the facet relief reduces tool load and chatter, helping you achieve consistent finishes and longer tool life even under demanding cycles.

• Corner Radius with R0.25: Ensures precise, repeatable corners and reduces finishing work on non-ferrous parts.
• 2-Flute Design with 45° Helix: Supports fast, smooth cutting and efficient chip evacuation for clean surfaces.
• Facet Relief for Stable Cutting: Optimizes flute geometry to minimize vibration and extend tool life in challenging profiles.

Using this end mill helps streamline workflows by delivering accurate radii, improving surface finishes, and reducing downtime from tool changes or rework. The carbide construction provides long wear resistance, making it a dependable choice for production runs and precision jobs alike, so you can trust consistent performance from setup to finish.
