Part of the XVE540 series, this head measures 0.625 inches in diameter with a 1\/64-inch (0.015-inch) corner radius that reduces stress concentration at the cutting edge and extends tool life in demanding applications. The SIRON-A coating provides enhanced hardness and heat resistance, making this head well suited for high-speed finishing passes on ferrous and non-ferrous materials. It is installed by machinists and CNC operators working in aerospace, die and mold, and general precision machining environments.\u003c\/p\u003e\u003cp\u003eThis end mill head is designed for use in modular tooling systems using an E16 connection interface. The 3-flute, right-hand helical design with a fixed 50-degree helix angle supports aggressive chip evacuation while maintaining a strong core. Center-cutting capability allows plunge entry where required. With a length of cut of 0.3346 inches and an overall length of 1.4016 inches, this head fits compact tooling setups where reach and rigidity must be balanced. It is intended for use on CNC machining centers running standard cutting fluids supplied externally, as this head does not support coolant-through delivery.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in precision milling\u003c\/li\u003e\n\u003cli\u003eSIRON-A coating for improved hardness and thermal stability at the cutting edge\u003c\/li\u003e\n\u003cli\u003e1\/64-inch corner radius reduces edge chipping and improves surface finish\u003c\/li\u003e\n\u003cli\u003e50-degree fixed helix angle with right-hand flute direction for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry supports direct plunge entry\u003c\/li\u003e\n\u003cli\u003eE16 modular connection for use with compatible tooling systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with E16 modular tooling system interfaces as part of the SECO XVE540 series.
