ITC Carbide End Mill Corner Radius 3091 - 3 Flute 38° Helix Radius With Facet Relief - Non-Ferrous - 16mm x R4

The Carbide End Mill Corner Radius 3091 is a high-performance cutting tool built for non-ferrous metals. With a 16 mm diameter and a 4 mm corner radius (R4), this three-flute carbide end mill is tuned for pocketing, contouring, and finishing where precise corners and clean edges matter. Its robust carbide body and optimized geometry make it a reliable choice for professionals who need consistent results in aluminum, copper, brass, and similar alloys.

In addition to the core geometry, this cutter features a 38° helix and facet relief. The helix angle supports efficient material removal and smooth chip flow, while facet relief reduces rubbing at the cutting edge, helping to maintain edge life and deliver a smoother surface finish. The 3-flute design provides a balanced combination of strength, rigidity, and good surface quality, even in demanding non-ferrous applications.

• Corner Radius with facet relief: Delivers precise corner radii for accurate pockets and contours while reducing edge rubbing for longer tool life and better surface finish.
• 38° helix with 3 flutes: Combines strong cutting action with effective chip evacuation and stable cutting in non-ferrous materials, resulting in smoother cuts and reliable performance.
• Rigid carbide in a 16 mm diameter: Durable carbide construction and sized geometry provide dependable performance in aluminum, copper, and other non-ferrous metals with consistent tool life.

The End Mill Corner Radius 3091 is a dependable choice for shops that demand precision, repeatable results, and efficient machining workflows. Its combination of corner radius, facet relief, and optimized helix supports high-quality finishes, tight tolerances, and reduced downtime, helping you finish jobs faster and more accurately with less rework.
