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 robust carbide construction and 1-inch shank diameter, this end mill provides the rigidity needed for aggressive cutting operations while maintaining precision. The variable helix design helps disperse cutting forces and minimize vibration, resulting in cleaner cuts and longer tool life. Whether you're working on production runs or precision prototyping, this professional-grade end mill delivers the reliability and performance that machinists demand.
