Built from M7 high speed steel with a titanium nitride (TiN) finish, this tool offers improved surface hardness and wear resistance compared to uncoated HSS tooling. It features a 5\/8 inch cutting diameter, a 1-5\/16 inch length of cut, and a 30-degree right-hand spiral flute geometry. The centercutting design allows for plunge milling in addition to peripheral and slot milling. This end mill is sized for use in standard milling machines, CNC machining centers, and manual knee mills requiring a 5\/8 inch shank.\u003c\/p\u003e\u003cp\u003eThis end mill suits residential shop and industrial production applications where ferrous and non-ferrous materials are machined. The 2-flute configuration provides good chip clearance, making it well suited for slotting and pocketing operations in softer steels, aluminum, and plastics. The regular length body keeps deflection low in standard-depth cuts. Machinists, toolroom operators, and CNC programmers specify this tool for everyday roughing and finishing passes where HSS tooling is preferred over carbide.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM7 high speed steel construction for toughness and regrindability\u003c\/li\u003e\n\u003cli\u003eTiN coating increases surface hardness and extends tool life in abrasive cuts\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand spiral flute promotes smooth chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry into workpiece\u003c\/li\u003e\n\u003cli\u003e2-flute design maximizes chip clearance for slotting and deep pocketing\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute — compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard single-end square end mill with a 5\/8 inch straight shank, compatible with milling machine collets, end mill holders, and chucks sized for 5\/8 inch shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed and serviced by machinists and CNC operators. Always power down and lock out the machine spindle before loading or removing end mills. Secure the shank fully within the collet or holder to the recommended engagement depth and verify runout with a dial indicator before beginning a cut. Do not exceed the tool manufacturers recommended speeds and feeds for the workpiece material and tool diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/16 inch (1.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 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 (M7 grade)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003eLength Type\u003c\/strong\u003e: Regular\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: E8030040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753027010866,"sku":"E8030040","price":68.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bcbb1161311c99319130dd60eaec2297.jpg?v=1788932226","url":"https:\/\/voomisupply.com\/products\/hertel-e8030040-square-end-mill-5-8-in-2-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
