ITC Carbide End Mill Corner Radius 3091 - 3 Flute 38° Helix Radius With Facet Relief - Non-Ferrous - 20mm x R2

The ITC Carbide End Mill Corner Radius 3091 is a precision cutting tool designed for non-ferrous machining. With a 20 mm diameter and a 2 mm corner radius, this 3-flute end mill delivers accurate grooves and clean radii on aluminum, copper, and other soft alloys. Engineered for professionals, it combines a 38° helix with corner radius and facet relief to optimize chip flow, stabilize cutting, and achieve a superior surface finish.

• 38° Helix with 3 Flutes for Efficient Chip Evacuation: The 38-degree angle and three flutes maximize chip removal and heat control, promoting smoother cuts in aluminum and other non-ferrous metals.
• Precise 2 mm Corner Radius for Consistent Radii: The built-in corner radius guarantees uniform corners on every part, improving fit, reducing secondary finishing, and delivering repeatable results.
• Facet Relief for Durability and Stable Finish: The facet relief minimizes rubbing at the tooth—extending tool life and delivering consistent surface quality even under demanding feeds and speeds.

This end mill helps you maintain tight tolerances, achieve clean finishes, and shorten cycle times in non-ferrous materials. Its carbide hardness, geometry, and relief work together to provide reliable performance, reduce downtime, and support consistent results across daily production or precision prototyping.
