It features a 3\/8 inch cutting diameter, a 0.02 inch corner radius, and five flutes with variable index and variable helix geometry. The long-length design delivers a 1-1\/2 inch length of cut and a 4 inch overall length. Right-hand cutting and right-hand flute spiral are standard. The submicron carbide grade supports both roughing and finishing operations in demanding materials. It is sized for standard end mill toolholders with a 3\/8 inch straight-cylindrical shank held to h6 tolerance.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for machining shops, tool rooms, and production environments working in steel, stainless steel, superalloys, titanium, and cast iron. The corner radius geometry reduces chipping at the cutting edge and extends tool life in interrupted cuts and high-feed applications. The long flute length accommodates deeper axial engagement without requiring extended-reach tooling. Variable helix and variable index design help reduce harmonics and chatter during aggressive cuts. It is centercutting, allowing plunge entry as part of a milling strategy.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch cutting diameter with matching 3\/8 inch straight-cylindrical shank at h6 tolerance\u003c\/li\u003e\n  \u003cli\u003e0.02 inch corner radius for edge strength and reduced chipping\u003c\/li\u003e\n  \u003cli\u003eFive flutes with variable helix and variable index for chatter reduction\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch length of cut in a long-length 4 inch overall configuration\u003c\/li\u003e\n  \u003cli\u003eSolid submicron carbide construction for wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eCentercutting and right-hand spiral for versatile milling entry and chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard end mill toolholders.
