Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention that standard HSS tooling cannot match. The 2-inch cutting diameter pairs with a 1-5\/8-inch length of cut and a 2-flute spiral configuration at a 30-degree helix angle, producing efficient chip evacuation and smooth cutting action. Centercutting geometry allows plunge entry in addition to peripheral and slot milling operations. This is a right-hand cut, right-hand flute tool in an uncoated finish, suited for machinists and tool-and-die shops running manual or CNC milling machines.\u003c\/p\u003e\n\u003cp\u003eThe E2030927 is used in general machining environments where a large-diameter end mill is required for roughing or semi-finishing passes. The 3\/4-inch shank diameter fits standard milling chucks, collet holders, and end mill adapters commonly found in knee mills, vertical machining centers, and bridge-port style machines. Its regular-length classification and 4-1\/8-inch overall length make it practical for standard reach applications without extension holders. No chipbreaker geometry is present, keeping the cutting edge geometry straightforward for conventional milling paths.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for improved hot hardness and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003e2-inch cutting diameter with 1-5\/8-inch length of cut for substantial material engagement\u003c\/li\u003e\n  \u003cli\u003e2-flute spiral design at 30-degree helix angle promotes efficient chip flow\u003c\/li\u003e\n  \u003cli\u003eCentercutting capable — supports plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute configuration for conventional spindle rotation\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — compatible with cutting fluids and oils for extended tool life\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for standard 3\/4-inch shank end mill holders used in vertical milling machines and CNC machining centers requiring a 2-inch diameter cobalt square end mill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Secure the shank fully into the tool holder to the minimum insertion depth recommended by the holder manufacturer before tightening. Power down and lock out the spindle drive before changing tooling. Verify runout with a dial indicator after clamping to avoid premature edge wear and surface finish issues.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inches (1.625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\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\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.504 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: E2030927\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51755613684018,"sku":"E2030927","price":405.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d1adcfb1929874be1fb478a8e387ab49.jpg?v=1788956920","url":"https:\/\/voomisupply.com\/products\/hertel-e2030927-2-inch-cobalt-square-end-mill-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
