It features a 3\/4-inch (0.750 inch) mill diameter, a 0.09-inch corner radius, and 7 flutes configured in a right-hand helical, close-pitch arrangement. The single-end tool runs at a high helix angle and is built from submicron-grade carbide, delivering the rigidity and edge retention required when cutting steel, stainless steel, superalloys, titanium, and cast iron. Licensed machinists and CNC operators use this tool for precision finishing passes where surface finish and dimensional accuracy are critical.\u003c\/p\u003e\n\u003cp\u003eThe 312730 is suited for finishing cuts in ferrous and high-temp alloy materials in both job shop and production environments. With a 1-inch length of cut and a 3-inch overall length, it fits standard end mill holders with a straight cylindrical shank held to an h6 tolerance. The short flute length and close pitch make it a stable choice for applications where chatter control and tight tolerances matter most. Secondary workpiece material compatibility includes cast iron.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-inch (0.750 inch) mill diameter with matching 3\/4-inch straight-cylindrical shank to h6 tolerance\u003c\/li\u003e\n  \u003cli\u003e0.09-inch corner radius reduces stress concentration and extends tool life at workpiece corners\u003c\/li\u003e\n  \u003cli\u003e7 flutes in a close-pitch, right-hand helical configuration optimized for finishing\u003c\/li\u003e\n  \u003cli\u003eSubmicron solid carbide construction for hardness and wear resistance in tough alloys\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows plunge entry\u003c\/li\u003e\n  \u003cli\u003eShort flute length type for maximum rigidity in precision finishing passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard end mill holders.
