It features a 3\/8-inch cutting diameter, a 0.0200-inch corner radius, and four right-hand spiral flutes with a 40-degree high helix angle. The cutting edge measures 7\/8 inch (0.8750 inches) in length of cut, and the tool runs 2.5 inches overall length. An AlCrN (aluminum chromium nitride) PVD coating provides thermal resistance and wear protection, making this end mill well-suited for prolonged cuts in hard and abrasive workpiece materials. It is centercutting and configured for both roughing and finishing passes in a single tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual mills where stainless steel, superalloys, titanium, and hard materials are the primary workpiece materials. The STR440 series is engineered for short-flute, high-rigidity applications requiring tight dimensional tolerances. The 3\/8-inch Weldon flat shank mounts in standard toolholders. It is a single-end tool with right-hand cutting direction and normal pitch flute spacing, appropriate for production environments and job shop applications where tool life in difficult materials is a priority.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eAlCrN PVD coating rated for stainless steel, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003e0.0200-inch corner radius protects the cutting edge and reduces stress concentrations at corners\u003c\/li\u003e\n  \u003cli\u003e40-degree high helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank provides positive drive and prevents slippage in toolholders\u003c\/li\u003e\n  \u003cli\u003eSuitable for both roughing and finishing operations in a single setup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard toolholders accepting a 3\/8-inch Weldon flat shank.
