Built from M7 high speed steel with a titanium nitride (TiN) finish, it carries a 5\/8 inch cutting diameter, a 1-1\/8 inch length of cut, and a 4-1\/2 inch overall length. The 30-degree spiral flute geometry promotes efficient chip evacuation and smooth cutting action. This is a centercutting tool, allowing plunge entry directly into a workpiece. Machinists and toolroom operators install this type of end mill on manual knee mills, CNC machining centers, and benchtop milling machines.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard applications in job shops, maintenance toolrooms, and production environments where a reliable HSS general-purpose cutter is needed. The double-end configuration extends tool life by providing two usable cutting ends before the tool is retired. Right-hand cut and right-hand flute orientation suit the majority of conventional milling setups. The TiN coating adds surface hardness and reduces friction at the cutting edge, supporting longer tool life compared to uncoated HSS. The regular-length classification makes it suitable for typical depth-of-cut requirements without excessive overhang.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM7 high speed steel construction for toughness in interrupted cuts and general milling\u003c\/li\u003e\n\u003cli\u003eTiN (titanium nitride) coating increases surface hardness and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends per tool\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle with spiral flute promotes chip flow and reduces chatter\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 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-shank replacement or stock end mill for manual and CNC milling machines accepting a 5\/8 inch collet, end mill holder, or milling chuck.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the machine fully powered down and the spindle at a complete stop. Use a properly sized collet or end mill holder torqued according to the machine manufacturer's specification to prevent tool pullout. Inspect the shank and holder bore for chips or burrs before seating the tool. Follow your facility's lockout\/tagout procedures before any tooling change on a CNC machining center.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.125 inches (1-1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches (4-1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\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\u003eDouble End\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: 0.34 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: E8050040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732798177586,"sku":"E8050040","price":89.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4dfe8a6d2b50c55fd0f58054a88633ad.jpg?v=1788746932","url":"https:\/\/voomisupply.com\/products\/hertel-e8050040-square-end-mill-5-8-in-2-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
