The tool features a 0.9844-inch (25 mm) cutting diameter and accepts up to four screw-clamped R390-11 series inserts, delivering a 90-degree lead angle suited for true square-shoulder cuts. With a maximum depth of cut of 0.3937 inches (10 mm) and through-coolant capability, it handles aggressive material removal while maintaining thermal stability. The cylindrical shank measures 0.9844 inches (25 mm) in diameter. This tool is installed and operated by machinists and CNC programmers in production and job-shop settings.\u003c\/p\u003e\n\u003cp\u003eThe 5745469 is suited for milling steel, alloy, and similar workpiece materials in both roughing and semi-finishing shoulder milling applications. Its 4.7244-inch (120 mm) overall length and CoroMill 390 platform make it appropriate for vertical and horizontal machining centers equipped with standard cylindrical toolholding. Through-coolant delivery supports extended tool life and chip evacuation in deep shoulder passes. The tool body is constructed of steel and accepts multiple R390-11 T3 insert geometries, allowing operators to tune the cut for different material and surface-finish requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree lead angle for true square-shoulder milling\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design for improved chip evacuation and thermal control\u003c\/li\u003e\n  \u003cli\u003eAccepts 4 screw-clamped R390-11 T3 series inserts (multiple geometries compatible)\u003c\/li\u003e\n  \u003cli\u003eMaximum spindle speed of 36,500 RPM for high-speed machining center use\u003c\/li\u003e\n  \u003cli\u003eCylindrical shank for straightforward toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eSteel tool body construction for rigidity and durability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with the following R390-11 T3 series inserts: R390-11 T3 04M-PM, R390-11 T3 08E-PL, R390-11 T3 08M-PM, R390-11 T3 16E-PM, R390-11 T3 16M-KM, and R390-11 T3 16M-PM.
