Built around the CoroMill 390 platform, it accepts 7 R390-17.. style inserts and delivers a 90-degree lead angle with positive rake geometry for clean, efficient chip formation. The cutter body is machined from steel and sized at 4 inches maximum cutting diameter with a 1-1\/2 inch arbor hole, making it a standard fit for horizontal and vertical milling machine spindles. Maximum depth of cut is 15.70 mm (0.618 inches), and overall height is 50.01 mm (1.969 inches). Insert retention uses a clamp-and-screw method for secure tool engagement under heavy feeds.\u003c\/p\u003e\n\u003cp\u003eThis face mill is suited for square-shoulder and face milling operations on ferrous and non-ferrous workpiece materials in production machining settings. Typical applications include roughing and semi-finishing passes on steel and cast iron components in job shops, aerospace part manufacturing, and general industrial machining. The close pitch configuration with 7 insert pockets supports high metal removal rates where machine rigidity allows. Right-hand cutting direction is standard. This tool is handled and installed by machinists and CNC setup technicians operating vertical machining centers, horizontal mills, and manual knee mills equipped with the appropriate arbor.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4 inch (101.60 mm) maximum cutting diameter for broad face milling passes\u003c\/li\u003e\n  \u003cli\u003e7-insert close-pitch configuration supports high material removal rates\u003c\/li\u003e\n  \u003cli\u003e90-degree lead angle produces true square shoulders with minimal radial force\u003c\/li\u003e\n  \u003cli\u003ePositive rake geometry reduces cutting forces and heat generation at the insert\u003c\/li\u003e\n  \u003cli\u003eClamp-and-screw insert retention provides rigid, repeatable tool holding\u003c\/li\u003e\n  \u003cli\u003eCoroMill 390 platform with R390-17.. insert compatibility for broad insert availability\u003c\/li\u003e\n  \u003cli\u003eSteel cutter body with 1-1\/2 inch arbor hole and 16.08 mm keyway width for positive drive\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with R390-17.. series inserts as specified by the manufacturer.
