The tool features a 1\/4 inch diameter, a 0.01 inch corner radius, and five flutes with a variable helix geometry that reduces harmonic vibration during cuts. An AlTiN (aluminum titanium nitride) PVD coating provides thermal resistance and extended tool life in abrasive and high-heat applications. This end mill is single-end, right-hand cutting, and center-cutting, making it suitable for both roughing and finishing operations in a single tool. Licensed machinists and CNC operators working with hardened materials will find this tool well matched to demanding production environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is engineered for use in steels up to 55 Rc, stainless steel, cast iron, and hard alloys. Its close pitch, variable helix flute design supports stable material removal across a range of cutting conditions. The 3\/4 inch length of cut and 2-1\/2 inch overall length suit it for standard-reach milling operations in machining centers and CNC mills. A straight-cylindrical 1\/4 inch shank is compatible with high-precision toolholders. This tool is part of the Harvey Tool End Mills for Hardened Steels - Corner Radius series and is intended for professional machine shop and production environments where dimensional accuracy and surface finish are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVariable helix flute geometry reduces chatter and vibration in hard material cuts\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating provides thermal and wear resistance for hardened steel applications\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capability allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003e0.01 inch corner radius protects the cutting edge and improves surface finish at workpiece corners\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute direction and right-hand cutting for standard CNC mill setup\u003c\/li\u003e\n  \u003cli\u003eSuitable for both roughing and finishing in a single tool pass\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in steels up to 55 Rc, stainless steel, cast iron, and hard alloys.
