ITC Carbide End Mill Corner Radius 2161 - 2 Flute 45° Helix With Facet Relief & Radius - Non-Ferrous - 12mm x R1

The ITC Carbide End Mill Corner Radius 2161 is a precision tool designed for high-performance machining in non-ferrous materials. With a 2-flute configuration and a 45° helix, it combines efficient chip evacuation with stable cutting to deliver consistent corner radii and clean finishes on aluminum, brass, copper, and similar metals.

Designed for professionals who demand accuracy and reliability, this 12 mm diameter end mill features a 1 mm corner radius and facet relief to help you achieve sharp, repeatable corners, smooth surface finishes, and reduced post-processing work across everyday production tasks.

• 1 mm Corner Radius for Consistent, Crisp Corners: Delivers repeatable corner radii on every pass, reducing post-process deburring and ensuring a precise fit for enclosures, molds, and fixtures.
• 2-Flute Design with 45° Helix for Efficient Chip Evacuation: Promotes rapid material removal in non-ferrous metals, minimizes built-up edge, and supports higher feed rates for faster cycle times and better surface finishes.
• Facet Relief for Stability and Longer Tool Life: Reduces rubbing and heat buildup, enhances cutting stability, and extends tool life in continuous machining of soft metals.

With its carbide construction and optimized geometry, the ITC Corner Radius 2161 enhances workflow by delivering reliable performance across common non-ferrous applications. The 12 mm diameter fits standard toolholders, while the 1 mm corner radius ensures clean internal features and consistent results. The combination of 2 flutes, a 45° helix, and facet relief enables smoother cuts, reduced downtime, and repeatable finishes you can trust for everyday machining tasks.
