With a 0.6875-inch cutting diameter and a 4-flute spiral configuration, this end mill delivers smooth material removal and excellent surface finish in ferrous and non-ferrous applications. The AlTiN (aluminum titanium nitride) coating adds heat resistance and extends tool life under aggressive cutting conditions. The 40-degree helix angle promotes chip evacuation and reduces cutting forces. This tool is installed and operated by machinists and CNC operators working in job shops, tool rooms, and production machining environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling contoured surfaces, cavities, and 3D profiling passes where a ball-nose geometry is required. The stub length classification keeps the tool rigid during cuts, making it a reliable choice for applications where tool deflection must be minimized. With a 3\/4-inch shank diameter and 3-inch overall length, it fits standard ER and end mill holders used in vertical machining centers and CNC milling machines. Right-hand cutting and right-hand flute direction are standard for conventional spindle setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.6875-inch (11\/16-inch) ball nose diameter for contour and 3D profiling work\u003c\/li\u003e\n\u003cli\u003e4-flute solid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides elevated heat resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStub length design maximizes stiffness and reduces deflection\u003c\/li\u003e\n\u003cli\u003eSingle-end, right-hand cut configuration for standard CNC spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard end mill holders and ER collet chucks accepting a 3\/4-inch shank diameter, compatible with vertical machining centers and CNC knee mills configured for right-hand cutting tools.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by machinists and CNC operators. Always power down and lock out the spindle before changing tooling. Secure the shank fully within the holder to the recommended grip depth and verify runout with a dial indicator before cutting.
