The ITC Carbide End Mill Corner Radius 2161 is a precision carbide tool designed for high-accuracy machining in non-ferrous materials. It features a 4 mm cutting diameter with a 0.5 mm corner radius (R0.5), a 2-flute design, and a 45° helix with facet relief to deliver stable cuts and clean edges. Ideal for professionals and hobbyists who need reliable, repeatable performance on aluminum, brass, copper, and similar alloys.
With its optimized geometry, this end mill promotes efficient chip evacuation and minimizes vibration, helping you achieve precise corners with fewer passes and less finishing work. The robust carbide construction provides durability and consistent results across a range of non-ferrous machining tasks.
- Precise Corner Radius for Consistent Details: Ensures uniform corner radii across parts, delivering repeatable finishes and reducing post-machining touch-ups.
- 45° Helix with Facet Relief for Smooth Cutting: Enhances chip flow and reduces cutting forces, resulting in better surface finish and longer tool life.
- Non-Ferrous-Optimized 2-Flute Carbide: Cuts aluminum, brass, and copper efficiently, minimizes built-up edge, and provides reliable performance in demanding jobs.
This end mill helps you streamline your workflow by delivering accurate, repeatable results with fewer passes, easier deburring, and less rework. Its robust carbide construction and optimized geometry support consistent performance across a range of non-ferrous materials, helping you finish parts faster and with greater confidence in every cut.
