Built on the CoroMill 390 platform, this cutter accepts six R390-11.. style inserts and delivers a 90-degree lead angle with a positive rake geometry. The maximum cutting diameter is 2.5 inches (63.50 mm), the arbor hole diameter is 0.75 inches (19.05 mm), and the maximum depth of cut is 10.00 mm (0.3937 inches). Overall height is 1.575 inches (40.01 mm). Inserts are secured via clamp and screw, and the cutter operates in a right-hand cutting direction. The steel toolholder body is built for close-pitch insert spacing.\u003c\/p\u003e\u003cp\u003eThis face mill is suited for square-shoulder milling on vertical and horizontal machining centers in both production and job-shop environments. The close-pitch, six-insert configuration supports higher feed rates and stable cutting conditions on ferrous and non-ferrous materials. It is used by machinists and CNC operators running the CoroMill 390 series tooling system. No coolant-through capability is available on this body, so external coolant application is standard practice in most setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCoroMill 390 series platform with 90-degree lead angle for true square-shoulder profiling\u003c\/li\u003e\n\u003cli\u003eSix-insert close-pitch configuration for higher productivity and stable cutting\u003c\/li\u003e\n\u003cli\u003eR390-11.. compatible inserts secured by clamp and screw for reliable edge positioning\u003c\/li\u003e\n\u003cli\u003ePositive rake geometry reduces cutting forces and heat generation at the insert\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction; steel toolholder body for rigidity\u003c\/li\u003e\n\u003cli\u003eKeyway width of 0.3839 inches (9.75 mm) for accurate arbor drive engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with R390-11.. series inserts.
