ITC Carbide End Mill Corner Radius 3091 - 3 Flute 38° Helix Radius With Facet Relief - Non-Ferrous - 10mm x R0.5

The ITC Carbide End Mill Corner Radius 3091 is a high-performance cutting tool designed for non-ferrous metals like aluminum and brass. With a 10 mm diameter, an R0.5 corner radius, and a precise 3-flute geometry, it delivers accurate radii, clean edges, and reliable chip control across a range of pocketing and profiling tasks. The 38° helix combined with facet relief helps maintain stable cuts and a smooth surface finish, making it suitable for both production and precision work.

• Corner radius with facet relief: Delivers precise, repeatable R0.5 corners and a refined surface finish, while facet relief minimizes rubbing and heat buildup for longer edge life.
• 38° helix and efficient chip evacuation: Encourages steady cutting and effective chip removal in non-ferrous materials, reducing built-up edge and improving dimensional accuracy on each pass.
• 3-flute carbide design with 10 mm shank: Balances rigidity and material removal for predictable performance in soft metals, with a standard 10 mm shank that fits common tool holders for reliable, compatible operation.

This end mill is engineered to improve workflow and results: you get consistent radii, smoother finishes, and fewer tool changes thanks to durable carbide construction and optimized geometry. Whether pocketing, profiling, or finishing tight radii in aluminum or brass, the 3091 delivers dependable performance, repeatable accuracy, and long tool life that help boost productivity on busy CNC machines.
