It features a 0.75 inch diameter cutting edge with a 3 inch length of cut, a 0.75 inch shank, and a 5.25 inch overall length. The M42 cobalt steel construction provides elevated heat and wear resistance compared to standard high-speed steel tooling. With four right-hand spiral flutes at a 30-degree helix angle, this end mill delivers efficient chip evacuation and stable cutting performance in slotting, profiling, and peripheral milling operations. It is intended for use by machinists and tool and die professionals working on manual or CNC machines.\u003c\/p\u003e\n\u003cp\u003eThis long-series end mill is suited for applications requiring extended reach beyond standard length tooling. The 3 inch length of cut allows access into deeper pockets and slots where standard-length tools cannot reach. Its spiral flute geometry and 30-degree helix promote smooth cutting action across a range of workpiece materials. The right-hand cut and right-hand flute configuration is the standard orientation for conventional vertical and horizontal milling setups. This tool ships as a single unit and is intended for professional shop use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for improved heat resistance and tool life over standard HSS\u003c\/li\u003e\n  \u003cli\u003e0.75 inch cutting diameter with 3 inch length of cut for deep pocket and slot access\u003c\/li\u003e\n  \u003cli\u003eFour-flute spiral geometry at 30-degree helix for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard milling machine compatibility\u003c\/li\u003e\n  \u003cli\u003eLong-series length with 5.25 inch OAL for extended reach applications\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for use with cutting fluids on ferrous materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct substitute for 0.75 inch cobalt square end mills in long-series configurations used in standard vertical or horizontal milling machine setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists. The tool shank must be securely seated in a compatible collet or end mill holder rated for 0.75 inch shanks before operation. Confirm tool runout with a dial indicator before cutting.
