It features an 11\/16 inch (0.6875 inch) cutting diameter, a 1-5\/16 inch length of cut, and a 1\/2 inch shank diameter. The overall length is 3-5\/16 inches. The uncoated spiral flute geometry runs at a 30-degree helix angle with right-hand cut and right-hand flute orientation. Center-cutting capability allows this tool to plunge directly into workpiece material. It is suited for milling operations in job shops, maintenance environments, and production settings where HSS tooling is specified.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in manual mills and CNC machining centers running ferrous and non-ferrous materials at moderate cutting speeds. The regular-length profile and 1\/2 inch shank make it compatible with standard end mill holders, collet chucks, and Weldon-style tool holders. The 2-flute design provides good chip clearance in slotting applications and when cutting softer workpiece materials such as aluminum and mild steel. A licensed machinist or tooling technician typically selects and installs this tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e11\/16 inch cutting diameter with 1-5\/16 inch length of cut for regular-depth milling\u003c\/li\u003e\n\u003cli\u003eM7 high speed steel construction provides toughness and edge retention without a coating\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle spiral flute promotes smooth cutting action and chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry into solid material\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute configuration matches standard spindle rotation\u003c\/li\u003e\n\u003cli\u003e2-flute geometry maximizes chip clearance in slotting and full-width cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or production end mill for use with 1\/2 inch end mill holders, collet chucks, and Weldon-style adapters in manual and CNC milling equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips before seating the shank. Confirm the shank is inserted to the recommended minimum engagement depth for the holder type in use. Follow applicable machine tool safety standards and shop procedures when setting tool offsets and securing the holder.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 11\/16 inch (0.6875 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/16 inch (1.3125 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-5\/16 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M7\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\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: 0.22 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: E1030903\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730409423154,"sku":"E1030903","price":75.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c53231f78f09a0016608dab941011e4e.jpg?v=1788716957","url":"https:\/\/voomisupply.com\/products\/hertel-e1030903-square-end-mill-11-16-in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
