ITC Carbide End Mill Corner Radius 2161 - 2 Flute 45° Helix With Facet Relief & Radius - Non-Ferrous - 20mm x R2

The ITC Carbide End Mill Corner Radius 2161 is a precision cutting tool designed for non‑ferrous metals. It’s built to deliver clean edges and reliable performance in aluminum, copper, and similar alloys.

With a 20 mm diameter and a 2 mm corner radius, this 2‑flute end mill combines a 45° helix with facet relief to promote fast chip evacuation, stable cuts, and accurate corner radii from the first run.

• Efficient chip evacuation and smooth cutting: The 45° helix and facet relief design promote quick chip flow and reduce built‑up edge, helping maintain surface finish and extend tool life.
• Stable, chatter‑free performance in non‑ferrous materials: The 2‑flute geometry provides generous clearance and robust cutting action, reducing vibration for consistent results in aluminum and copper.
• Precise corner radius and durable construction: The R2 corner radius ensures defined fillets and repeatable geometry, while carbide construction delivers long tool life and reliable cuts.

This end mill is designed to fit standard 20 mm tooling setups and to streamline production workflows. Expect clean edges, accurate part geometry, fewer rework passes, and predictable performance across a range of non‑ferrous applications—from prototyping to high‑volume milling.
