The Kennametal 3866074 Corner Radius End Mill is engineered for precision milling in non-ferrous metals, featuring a 1" diameter and a 4-1/8" length of cut. Its 0.015" corner radius ensures smooth finishes and accurate contours, while the three-flute design enhances chip removal and tool stability. Constructed from solid carbide, this end mill offers exceptional hardness and wear resistance, extending tool life and maintaining cutting performance. The bright, uncoated finish reduces friction and heat buildup, making it suitable for high-speed machining applications. With a 37-degree helix angle, it provides efficient cutting action and reduced cutting forces, improving overall machining efficiency. The 1" shank diameter ensures compatibility with standard tool holders, facilitating easy integration into existing setups. This end mill is ideal for operations requiring precise corner radii and high-quality surface finishes in non-ferrous materials.
