ITC Carbide End Mill Corner Radius 3091 - 3 Flute 38° Helix Radius With Facet Relief - Non-Ferrous - 8mm x R0.25

The ITC Carbide End Mill Corner Radius 3091 is a precision carbide tool designed for non-ferrous materials. This 3-flute end mill features a 38° helix, a corner radius of R0.25, and facet relief to deliver clean, accurate corners and reliable performance. It’s an ideal choice for aluminum, brass, and copper workpieces where consistent finishes and precise radii matter.

Engineered for reliability in busy machining environments, the carbide body resists wear and the geometry supports long tool life, consistent results, and confidence in every cut.

• Corner Radius R0.25 for precise corners: Delivers accurate corner geometry that enhances fit and finish on non-ferrous parts while helping prevent corner chipping during demanding cuts.
• 38° Helix with 3 flutes for stable cutting: Balances aggressive material removal with smooth chip control, producing cleaner surfaces and extending tool life.
• Facet relief for non-ferrous efficiency: Minimizes built-up edge and promotes efficient chip flow, yielding consistent finishes on aluminum, brass, and copper with fewer finishing passes.

This end mill is designed to integrate seamlessly into standard CNC setups, delivering predictable performance across batches, reducing downtime, and enabling high-quality parts. With its precise radii, robust carbide construction, and optimized geometry, it supports repeatable results, improved throughput, and tight tolerances in non-ferrous milling applications.
