The tool carries a 1-inch cutting diameter and a 1.625-inch length of cut, with a 1-inch straight shank and a 4.125-inch overall length. The uncoated HSS construction suits general-purpose shop work where regrinding is common practice. Machinists and tool-and-die technicians are the primary installers on vertical mills, CNC machining centers, and knee mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for production and maintenance machining operations that require keyway cutting or conventional slot milling in steel, aluminum, cast iron, and similar materials. The centercutting geometry allows plunge entry directly into the workpiece, making it practical for blind pocket starts without a pre-drilled hole. The spiral flute design promotes chip evacuation and helps maintain surface finish across the full length of cut.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry for blind pocket and slot starts\u003c\/li\u003e\n  \u003cli\u003e2-flute spiral geometry promotes chip evacuation in slot and keyway cuts\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction supports regrinding to extend tool life\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for general-purpose ferrous and non-ferrous applications\u003c\/li\u003e\n  \u003cli\u003e1-inch straight shank compatible with standard ER and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct substitute for standard 1-inch diameter, 2-flute keyway end mills used in vertical milling machines and CNC machining centers accepting a 1-inch straight shank holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or toolroom technician. The machine spindle must be stopped and the tool holder verified clean and free of chips before securing the shank. Ensure the end mill is clamped to the full depth recommended by the tool holder manufacturer to prevent pullout under cutting loads. Do not exceed the feed and speed parameters appropriate for high speed steel tooling in the workpiece material being cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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: GG99914243\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753778512178,"sku":"GG99914243","price":130.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ca3d90bdf65885b59572c07e8620ae6a.jpg?v=1788940619","url":"https:\/\/voomisupply.com\/products\/hertel-gg99914243-keyway-end-mill-1-in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
