Built from high speed steel (HSS), it features a 0.75-inch cutting diameter, a 1.625-inch length of cut, and a 0.500-inch shank diameter, with an overall length of 3.625 inches. The three-flute geometry balances chip evacuation with rigidity, making it well suited for slotting, profiling, and peripheral milling in manual machines and CNC machining centers. The uncoated finish allows for easy regrinding, and the centercutting design enables direct plunge entry without a pre-drilled pilot hole.\u003c\/p\u003e\u003cp\u003eThis end mill is used in job shops, tool rooms, and maintenance machining environments where versatility and regrindability are priorities. The 0.500-inch shank fits standard R8, ER, Weldon, and similar toolholders common in vertical mills and CNC machining centers. The 3-flute configuration is a practical choice for aluminum and softer alloys where chip clearance matters, while still performing in mild steel at appropriate feeds and speeds. No variable helix, variable index, or chipbreaker geometry is present, keeping the tool profile straightforward for general work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.750-inch cutting diameter with 1.625-inch length of cut for slotting and profiling passes\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction supports regrinding and use with cutting oils in manual or lower-speed CNC applications\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003e3-flute geometry balances chip clearance and cutting edge strength\u003c\/li\u003e\n\u003cli\u003e0.500-inch straight shank fits widely available toolholding systems\u003c\/li\u003e\n\u003cli\u003eUncoated surface finish — no coating loss during regrind cycles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard single-end square end mill compatible with any toolholder accepting a 0.500-inch straight shank, including R8 collets, ER collet chucks, and Weldon-style end mill holders used on vertical knee mills and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Secure the shank in a clean, undamaged toolholder to the manufacturer-specified torque range for that holder type. Ensure the machine spindle is fully stopped and locked out before changing or adjusting tooling. Inspect the cutting edges for chips or wear before each use, and apply cutting fluid appropriate to the workpiece material to extend tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.750 inches (3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches (1-5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.500 inches (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.625 inches (3-5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eEnd Mill Style\u003c\/strong\u003e: Single End\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: E104304802\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753717170482,"sku":"E104304802","price":66.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4f8be40cbd2558afdfca21cc2e2bb933.jpg?v=1788939943","url":"https:\/\/voomisupply.com\/products\/hertel-e104304802-square-end-mill-3-4-in-hss-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
