It features a 5\/32 inch (0.1562 inch) cutting diameter, a 5\/16 inch (0.3125 inch) length of cut, and a 3\/16 inch (0.1875 inch) shank diameter. Overall length is 2 inches. The four-flute geometry with a 30-degree spiral helix and TiCN coating delivers efficient chip evacuation and extended tool life on ferrous and non-ferrous materials. The micrograin carbide substrate provides rigidity and edge retention in high-speed applications. This is a stub-length, centercutting, right-hand cut and right-hand flute end mill suited for slotting, profiling, and plunge operations.\u003c\/p\u003e\n\u003cp\u003eThe HERTEL 750491 is intended for use in CNC machining centers, knee mills, and manual milling machines where tight tolerances and fine finishes are required. Its stub-length configuration reduces deflection in short-reach applications, making it well suited for finish passes and shallow slot cutting in steel, stainless, aluminum, and similar materials. Machinists and tool-and-die professionals working in production or toolroom environments will find this tool appropriate for general-purpose milling tasks requiring consistent dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and extended tool life\u003c\/li\u003e\n  \u003cli\u003eTiCN finish reduces friction and improves wear resistance on hard materials\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral design with 30-degree helix for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry into workpiece\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration for standard spindle direction\u003c\/li\u003e\n  \u003cli\u003eStub-length design minimizes deflection in short-reach milling operations\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of +0.000 \/ -0.002 inches for close-tolerance work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for milling applications requiring a 3\/16 inch shank, compatible with standard collets and end mill holders accepting a 3\/16 inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist. Ensure the milling machine spindle is fully stopped and locked out before mounting or removing the end mill. Seat the shank fully into the collet or end mill holder and torque the retaining mechanism according to the toolholder manufacturer specifications. Verify runout with an indicator before commencing a cut to avoid premature tool failure or dimensional error.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/32 inch (0.1562 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/16 inch (0.3125 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 750491\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753230369074,"sku":"750491","price":40.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4748b60f8fc9b5522a64722f33bab85a.jpg?v=1788934133","url":"https:\/\/voomisupply.com\/products\/hertel-750491-square-end-mill-5-32-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
