ITC Carbide End Mill Corner Radius 3091 - 3 Flute 38° Helix Radius With Facet Relief - Non-Ferrous - 3mm x R0.5

ITC Carbide End Mill Corner Radius 3091 is a compact, high‑precision cutting tool built for non‑ferrous materials. It features a 3 mm diameter with a 0.5 mm corner radius and a 3‑flute design, paired with a 38° helix to optimize chip flow and cutting stability.
Its corner radius and facet relief are engineered for consistent radii, smooth surfaces, and reliable performance in aluminum, brass, and similar alloys—making it a dependable choice for both professional shops and serious hobbyists.

• Efficient chip evacuation with 38° helix and 3 flutes: The sharper helical angle plus multiple flutes move chips away from the cut, reducing heat, improving finish, and sustaining productivity on non‑ferrous work.
• Precise R0.5 corner radius for repeatable edges: Delivers uniform corners in pockets and detail features, improving fit and reducing rework on every part.
• Facet relief for stable cuts and better surface finish: Optimized relief geometry minimizes rubbing and chatter, extending tool life and delivering consistent surface quality across runs.

By combining these design elements, the 3091 End Mill enables reliable performance in busy production lines and workshop projects alike. Expect faster cycle times, cleaner radii, and fewer tool changes, with consistent results you can trust on aluminum, brass, and other non‑ferrous materials.
