It carries a 0.030-inch corner radius, a 0.5-inch cutting diameter, and four flutes with a variable helix design that reduces chatter and improves surface finish in difficult-to-machine materials. The AlTiN PVD coating adds thermal resistance and prolongs tool life in high-heat cutting environments. At 3 inches overall length with a 1-inch length of cut, this is a short-series tool well suited to rigid setups. It is single-end, centercutting, and right-hand cutting. Machinists, toolroom operators, and CNC programmers working in job shops and aerospace production environments will recognize this as a capable finishing and roughing tool in a single package.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits applications where tight tolerances and controlled surface finish are required on hard or exotic workpiece materials. The extended reach geometry, with a 1.5-inch reach length and a 0.480-inch neck diameter, allows access to deeper features without sacrificing rigidity. The micrograin carbide substrate maintains cutting edge integrity in abrasive and work-hardening materials. The STRN440.2 series is intended for use with standard straight-shank toolholders, and the 0.5-inch cylindrical shank is sized for common ER and side-lock holders found on CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide substrate for strength in hard and exotic materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating provides high-temperature resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eVariable helix flute geometry reduces harmonic vibration during cutting\u003c\/li\u003e\n  \u003cli\u003e0.030-inch corner radius reduces stress concentration at cutting corners\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge milling operations\u003c\/li\u003e\n  \u003cli\u003eExtended reach with 0.480-inch neck diameter for access to deeper part features\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with straight-shank cylindrical toolholders.
