It is designed for milling operations including slotting, profiling, and peripheral cutting on ferrous and non-ferrous materials. The cutter measures 0.625 inches in diameter with a 1.625-inch length of cut and a 3.75-inch overall length. With a 30-degree helix angle and four spiral flutes, it provides a good balance of chip evacuation and surface finish in general-purpose machining environments. This tool is installed by machinists and CNC or manual mill operators in job shops, maintenance facilities, and production settings.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for use on vertical milling machines, knee mills, and CNC machining centers. The centercutting geometry allows plunge cuts directly into the workpiece without pre-drilling. Right-hand cut and right-hand flute configuration is standard for conventional spindle setups. The uncoated M7 HSS construction makes it a practical choice for shops that regrind tooling in-house and for use on materials where coated carbide is not required. No chipbreaker or variable helix features are present, keeping this a straightforward general-purpose tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSquare end profile for slotting, facing, and profiling cuts\u003c\/li\u003e\n  \u003cli\u003eM7 high speed steel construction supports in-house regrinding\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth chip flow and reduced chatter\u003c\/li\u003e\n  \u003cli\u003eFour flutes provide improved finish compared to two-flute designs in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for use with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose single-end square end mill for use in standard ER collet chucks, end mill holders, and set-screw holders accepting a 0.625-inch shank diameter on vertical mills and CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or CNC operator. Secure the shank in a properly sized collet or end mill holder and verify runout before cutting. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Follow shop speeds-and-feeds guidelines for M7 HSS at the specified diameter and workpiece material; do not exceed the tool manufacturers recommended depth of cut for the selected material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 1.625 inches (1-5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 inches (3-3\/4 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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eMaterial Grade\u003c\/strong\u003e: M7\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\u003eEnd Type\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\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: 0.27 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: E1039040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744536985906,"sku":"E1039040","price":82.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6380e4cf4a1530e7c088ddaed9fe9f29.jpg?v=1788857732","url":"https:\/\/voomisupply.com\/products\/hertel-e1039040-square-end-mill-5-8-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
