With a 7\/16 inch cutting diameter and a 1 inch length of cut, this single-end tool handles slotting, profiling, and peripheral milling on ferrous and non-ferrous materials. The micrograin carbide substrate paired with an AlTiN coating supports elevated cutting temperatures and extended tool life in hardened steels and high-temperature alloys. A 40-degree helix angle promotes efficient chip evacuation and smooth cutting action across a range of feed rates and spindle speeds.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and manual mills in job shops, tool and die operations, and production machining environments. It is appropriate for use in both light finishing passes and moderate material removal on steel, stainless, and cast iron. The right-hand cut and right-hand spiral flute geometry are standard for conventional and climb milling setups. Licensed machinists and CNC operators are the primary installers and users of this tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN coating improves heat resistance and tool life in ferrous and hardened materials\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate provides rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003cli\u003eConsistent 7\/16 inch shank diameter matches standard collet and end mill holder sizes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide square end mill for standard 7\/16 inch collet chucks and end mill holders on CNC machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists following standard tooling change procedures. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully in the collet or holder and torque the retention nut per the holder manufacturer specification.
