This cutter features a 2-1\/2 inch (63.50 mm) maximum cutting diameter and accepts 5 R590-1105.. style inserts secured by clamp and screw holding. The 90-degree lead angle produces true square shoulders, while the positive rake geometry reduces cutting forces and extends insert life. Through-coolant capability is built in, delivering coolant directly to the cutting zone for improved chip evacuation and thermal control. Toolholder material is steel. Installed by machinists and CNC operators in production shop environments.\u003c\/p\u003e\n\u003cp\u003eThe 5740378 is suited for close-pitch square-shoulder milling in ferrous and non-ferrous materials where a true 90-degree wall is required. The CoroMill Century series cutter style RA590 is commonly applied in both roughing and semi-finishing passes on vertical machining centers. The 3\/4 inch arbor hole diameter and keyway width of 0.3839 inches fit standard arbor toolholding setups. Right-hand cutting direction is standard. This cutter is appropriate for production environments requiring consistent, repeatable shoulder profiles across moderate to high volumes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-1\/2 inch maximum cutting diameter with close-pitch 5-insert configuration for high metal removal rates\u003c\/li\u003e\n  \u003cli\u003e90-degree lead angle produces true square shoulders in a single pass\u003c\/li\u003e\n  \u003cli\u003ePositive rake geometry reduces cutting forces and extends insert life\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design delivers coolant directly to the cutting zone\u003c\/li\u003e\n  \u003cli\u003eCompatible insert style R590-1105.. secured by clamp and screw for repeatable edge positioning\u003c\/li\u003e\n  \u003cli\u003eSteel toolholder body with 3\/4 inch arbor hole and integral keyway for secure arbor mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with R590-1105.. compatible inserts (Complete Insert Compatibility: R590-1105..).
