It features a 3\/4 inch diameter, a 1-5\/8 inch length of cut, and a 4 inch overall length. The cutting end carries a 0.030 inch corner radius and five flutes with a 38-degree helix angle and variable index geometry, which helps reduce chatter and improve surface finish. An AlCrTiN coating provides elevated heat resistance and extended tool life in ferrous and hardened materials. This tool is center-cutting and suited for plunging, slotting, and profiling operations. It is installed and used by CNC machinists and tool and die professionals.\u003c\/p\u003e\n\u003cp\u003eThe 311785 is intended for use in vertical and horizontal CNC machining centers where high-feed, high-speed milling of steel, alloy steel, stainless steel, and hardened materials is required. Its micrograin solid carbide substrate combined with the AlCrTiN coating makes it well suited for aggressive material removal and finishing passes in tool rooms, job shops, and production floors. The single-end configuration and 3\/4 inch shank diameter allow direct mounting in standard tool holders sized for 3\/4 inch bore.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-flute design with 38-degree helix angle for efficient chip evacuation and reduced vibration\u003c\/li\u003e\n  \u003cli\u003eVariable index geometry minimizes harmonic chatter during heavy cuts\u003c\/li\u003e\n  \u003cli\u003eAlCrTiN coating delivers high-temperature wear resistance for extended tool life\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate provides rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003e0.030 inch corner radius protects the cutting edge and reduces stress concentrations in workpiece corners\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capability allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard CNC machining center tool holders with a 3\/4 inch bore.
