The tool features a 3\/8 inch cutting diameter with a 0.06 inch corner radius, four flutes, and a TiAlN (titanium aluminum nitride) PVD coating that extends tool life in high-temperature cutting conditions. The overall length is 4 inches, with a 1\/2 inch length of cut and a Weldon flat shank for secure toolholder engagement. The variable index geometry and medium helix design support both roughing and finishing passes in a single setup, making this end mill a practical choice for production machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The extended reach configuration, with a reach length of 1.875 inches and a neck diameter of 0.353 inches, allows access to deeper pockets and shoulder features without sacrificing rigidity. The centercutting design permits plunge entry, and the right-hand flute direction and right-hand cutting orientation are standard for conventional CNC vertical or horizontal milling centers. This tool is appropriate for job shops, aerospace suppliers, and manufacturing facilities working with difficult-to-machine alloys.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiAlN PVD coating for extended tool life in high-heat cutting of steel, stainless, and superalloys\u003c\/li\u003e\n  \u003cli\u003e0.06 inch corner radius reduces stress concentration and improves surface finish at part edges\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces chatter and harmonic vibration during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank provides positive drive and resists pullout in high-feed toolholders\u003c\/li\u003e\n  \u003cli\u003eExtended reach with 1.875 inch reach length suits deep pocket and stepped shoulder applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard Weldon flat toolholders.
