Built on the CoroMill 245 platform, this cutter accepts five R245-12T3 series inserts and delivers a maximum depth of cut of 0.24 inches (6.10 mm) with a 45-degree lead angle and positive rake geometry. The 4-inch maximum cutting diameter and 1-1\/2-inch arbor hole diameter make it well-suited for horizontal and vertical milling machines. Installed by machinists and toolroom professionals, this face mill is a direct-fit tool for shops requiring consistent square-shoulder profiles on ferrous and non-ferrous workpieces.\u003c\/p\u003e\n\u003cp\u003eThe 5740089 is intended for use in production machining, job shop milling, and toolroom applications where repeatable square-shoulder cuts are required. The CoroMill 245 series is a recognized platform in face milling operations, and this cutter body is sized for mid-range spindle equipment. The right-hand cutting direction and clamp-and-screw insert holding method are standard configurations for this class of milling cutter. No specific compatible machine models or systems beyond the CoroMill 245 series designation are stated in the product data.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch maximum cutting diameter with 1-1\/2-inch arbor hole for standard arbor mounting\u003c\/li\u003e\n  \u003cli\u003eAccepts 5 R245-12T3 series indexable inserts with clamp and screw holding method\u003c\/li\u003e\n  \u003cli\u003e45-degree lead angle with positive rake geometry for efficient chip formation\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.24 inches (6.10 mm) per pass\u003c\/li\u003e\n  \u003cli\u003eOverall cutter height of 50.00 mm (1.97 inches) with 16.08 mm keyway width\u003c\/li\u003e\n  \u003cli\u003eSteel toolholder body, right-hand cutting direction, no coolant-through design\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with R245-12T3 series indexable inserts within the SANDVIK COROMANT CoroMill 245 platform.
