This precision-engineered 4-flute carbide corner radius end mill from RedLine Tools delivers exceptional performance for demanding machining applications. Featuring a 3/4-inch cutting diameter and a 0.015-inch corner radius, this American-made tool combines variable helix and variable index geometry to reduce chatter and improve surface finish. The advanced AlTiSN coating enhances wear resistance and extends tool life, making it ideal for machining a wide range of materials. With its 1-inch shank diameter and robust carbide construction, this end mill provides the rigidity needed for aggressive cutting operations while maintaining dimensional accuracy. The variable helix design minimizes harmonic vibrations during high-speed machining, resulting in smoother cuts and longer tool life. Whether you're working on production runs or precision prototyping, this corner radius end mill offers the reliability and performance that professional machinists demand.
