ITC Carbide End Mill Corner Radius 3091 - 3 Flute 38° Helix Radius With Facet Relief - Non-Ferrous - 20mm x R3

Introducing the ITC Carbide End Mill Corner Radius 3091 — a precision tool designed for reliable non‑ferrous machining. This 20 mm diameter end mill with an R3 corner radius combines a 3‑flute design and a 38° helix to deliver stable cuts, efficient chip evacuation, and a clean, accurate edge for aluminum, copper, and other non‑ferrous materials.

• 38° Helix for Efficient Chip Evacuation: The 38° helix angle promotes smooth chip lifting away from the cut, reducing heat buildup and chatter for consistent, controllable performance across a range of feeds and speeds.
• Corner Radius R3 for Precise Edges: The R3 corner radius maintains sharp, repeatable radii on outer features while minimizing edge chipping, helping you achieve precise corners and high-quality part finishes.
• Facet Relief for Stability and Finish: The facet relief minimizes rubbing and built‑up heat, supporting a cleaner surface finish and longer tool life in non‑ferrous materials.

Designed for professionals who demand accuracy and reliability, this end mill helps you deliver consistent results with fewer reworks, smoother finishes, and dependable performance in demanding non‑ferrous applications. Its balanced geometry and robust carbide construction make it a trustworthy choice for everyday milling, pocketing, and contouring tasks.
