The cutter measures 0.498 inches in diameter with a 1 inch length of cut and a 3 inch overall length. The 1\/2 inch shank diameter fits standard end mill holders and collet chucks used on vertical machining centers and manual knee mills. An uncoated finish makes this tool straightforward to resharpen, and the 30-degree helix angle promotes smooth chip evacuation during cutting operations. This end mill is intended for machinists, tool and die makers, and maintenance shops performing keyway work or slotting on ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for light-to-moderate slotting and keyway operations on steel, aluminum, and similar workpiece materials in job shop, maintenance, and production environments. The centercutting geometry allows the tool to plunge directly into the workpiece, providing flexibility for closed-pocket and slot-entry cuts without a pre-drilled hole. The 2-flute configuration keeps chip clearance open in softer materials and during slot milling where chip packing is a concern.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.498 inch mill diameter for standard keyway and slotting work\u003c\/li\u003e\n  \u003cli\u003e2-flute spiral design promotes chip clearance during slot cuts\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction supports resharpening and general-purpose use\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle for smooth cutting action and reduced chatter\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — no specialized coating concerns during regrind\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-stock end mill for use in any end mill holder or collet chuck accepting a 1\/2 inch shank diameter on vertical machining centers, CNC mills, or manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Tighten the collet or set screw to the holder manufacturer's specified torque rating. Verify runout with a dial indicator before beginning the cut, and confirm appropriate speeds and feeds for the workpiece material before engaging the cutter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.498 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Uncoated\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: GG99914234\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51731704611122,"sku":"GG99914234","price":51.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d9fd983da8b8c5f4265f0518c682138.jpg?v=1788734064","url":"https:\/\/voomisupply.com\/products\/hertel-gg99914234-keyway-end-mill-0-498in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
