It features an 11\/16 inch (0.6875 inch) cutting diameter, a 1-5\/8 inch length of cut, and a 5\/8 inch shank diameter, with an overall length of 3-3\/4 inches. The 30-degree spiral flute geometry promotes efficient chip evacuation and stable cutting across a range of milling operations. Designed for right-hand cut and right-hand flute orientation, this end mill is centercutting, allowing plunge entry into the workpiece. It is uncoated and suited for general-purpose milling in job shop and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill is used in vertical and horizontal milling machines and machining centers for profiling, slotting, and peripheral milling operations. The regular-length configuration and 4-flute design make it a practical choice for ferrous and non-ferrous materials where finish and tool life balance is required. Machinists and toolroom technicians working in manufacturing, maintenance, and fabrication shops will find this a standard-duty workhorse for everyday milling tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM7 high speed steel construction for durability in general-purpose milling\u003c\/li\u003e\n\u003cli\u003e4-flute design balances chip clearance with surface finish quality\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle supports smooth cutting action and chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute orientation for standard milling setups\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use with cutting fluids on a wide range of materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard square end mill replacement for applications requiring an 11\/16 inch diameter, 5\/8 inch shank, regular-length 4-flute HSS end mill in conventional milling machines and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the shank in a properly sized collet, end mill holder, or Weldon-style holder torqued to the machine manufacturer's specification. Confirm runout with a dial indicator before beginning a cut, and apply appropriate cutting fluid for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 11\/16 inch (0.6875 inch)\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: High Speed Steel, Grade M7\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: 5\/8 inch (0.625 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/4 inches\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: GG039044\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727555264818,"sku":"GG039044","price":87.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/334effc6210faef2c7506835e4f56745.jpg?v=1788679289","url":"https:\/\/voomisupply.com\/products\/hertel-gg039044-square-end-mill-11-16-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
