It cuts a 17\/64 inch (0.2656 inch) diameter path with a length of cut of 11\/16 inch (0.6875 inch). The 3\/8 inch shank fits standard milling machine collets and tool holders. Four spiral flutes with a 30-degree helix angle clear chips efficiently during peripheral and slot milling operations. The right-hand cut, right-hand flute geometry is standard for conventional and climb milling. This uncoated end mill is suited for machinists and toolroom professionals working with ferrous and non-ferrous metals in manual mills and CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in toolroom, job shop, and production machining environments where a general-purpose square end profile is required. The double-end design extends tool life by providing two usable cutting ends before the tool is retired. With an overall length of 3-3\/8 inches and a regular length-of-cut classification, this tool fits standard short-reach milling applications. It is not center-cutting, so it is not suited for direct plunge operations without a pre-drilled start hole. Typical applications include side milling, slotting, and profiling on knee mills and CNC vertical machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM7 high speed steel construction for durability across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eDouble-end design provides two cutting ends per tool, extending usable service life\u003c\/li\u003e\n  \u003cli\u003eFour spiral flutes at 30-degree helix angle promote efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute geometry for standard milling setups\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — suitable for regrinding and resharpening in the toolroom\u003c\/li\u003e\n  \u003cli\u003eNot center-cutting — designed for peripheral and slot milling, not plunge entry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard toolroom end mill for use in any milling machine or machining center equipped with a 3\/8 inch collet or end mill holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom personnel. Power down and lock out the machine spindle before securing or changing the end mill in the collet or tool holder. Ensure the shank is seated to the full recommended depth in the holder and that all set screws or collet nuts are properly torqued per the tool holder manufacturer specifications. Because this end mill is not center-cutting, always use a pre-drilled hole or ramp entry when initiating a slot cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 17\/64 inch (0.2656 inches)\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: 11\/16 inch (0.6875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/8 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\u003eCenter Cutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Double End\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: 0.07 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: E1051017\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51746293940530,"sku":"E1051017","price":38.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/59051af0ed0a1c92255166c9daabec0e.jpg?v=1788868072","url":"https:\/\/voomisupply.com\/products\/hertel-e1051017-square-end-mill-17-64-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
