ITC Carbide End Mill Corner Radius 2161 - 2 Flute 45° Helix With Facet Relief & Radius - Non-Ferrous - 4mm x R1

The ITC Carbide End Mill Corner Radius 2161 is a precision cutting tool designed for non-ferrous machining. With a 4 mm cutting diameter and a 1 mm corner radius, this 2-flute end mill uses a 45° helix, facet relief, and an integrated radius to deliver clean, accurate corners, efficient chip evacuation, and stable cutting across aluminum, copper, brass, and other non-ferrous metals.

• Precise corner radius for repeatable accuracy: Delivers consistent edge geometry on every pass, reducing the need for secondary finishing and helping parts meet tight tolerances.
• Efficient chip evacuation with 45° helix and facet relief: Chips flow away smoothly, minimizing rubbing and heat buildup for cleaner cuts and longer tool life.
• 2-flute design for smooth cutting in non-ferrous metals: Lower cutting forces in soft metals enable faster material removal, improved surface finish, and reliable performance across alloys like aluminum, copper, and brass.

Whether you're tackling high-precision prototypes or ongoing production work, this end mill helps you complete parts faster with fewer finishing steps. The carbide construction, combined with the radius and geometry, supports consistent corner quality, stable cutting, and dependable performance on a range of non-ferrous materials.
