The cutter measures 0.499 inches in diameter with a 1-inch length of cut and a 3-inch overall length. The 1\/2-inch shank diameter fits standard ER collets and end mill holders. The uncoated HSS construction suits general-purpose machining environments where regrinding or cost-conscious tooling choices are priorities. A 30-degree helix angle promotes smooth chip evacuation during slotting passes, and the centercutting geometry allows plunge entry without a pre-drilled pilot hole.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in manual mills, knee mills, and CNC machining centers for keyway and slot applications in maintenance, repair, and production environments. It is well suited for tool rooms, machine shops, and industrial maintenance departments where standard keyway dimensions require a near-half-inch cutter. The uncoated finish makes it compatible with a wide range of cutting fluids and regrinding services.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.499-inch cutting diameter for precise keyway fits\u003c\/li\u003e\n  \u003cli\u003e1-inch length of cut for standard keyway depth requirements\u003c\/li\u003e\n  \u003cli\u003e2-flute geometry optimized for slotting and keyway operations\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes chip flow and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eUncoated high speed steel construction supports regrinding\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard keyway end mill with a 1\/2-inch shank, compatible with ER collet chucks, end mill holders, and side-lock holders sized for 1\/2-inch straight shanks on manual and CNC milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinist or toolroom personnel. Secure the shank fully within the collet or holder to the recommended grip depth before tightening. Verify spindle runout before cutting to protect the cutting edge and maintain keyway tolerance. Always bring the machine to a full stop before tool changes and confirm workpiece clamping is rigid before beginning any slotting pass.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.499 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\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\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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: 0.16 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: E116303201\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749295227186,"sku":"E116303201","price":48.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5fd584e79d2a2a00109d4e7a98aedd3c.jpg?v=1788904185","url":"https:\/\/voomisupply.com\/products\/hertel-e116303201-keyway-end-mill-0-499-in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
