Ground from M7 high speed steel, it runs without a coating and relies on the inherent toughness of M7 to handle interrupted cuts and moderate feeds. The mill measures 0.75 inches in diameter with a matching 0.75-inch shank, a 3-inch length of cut, and a 5.25-inch overall length, placing it in the long-series category. The 42-degree helix spiral flute geometry promotes chip evacuation and reduces cutting forces on the workpiece. It is a right-hand cut, right-hand flute tool suitable for manual and CNC milling machines.\u003c\/p\u003e\n\u003cp\u003eThis end mill is appropriate for job shops, tool rooms, and maintenance machining environments where a long-reach, two-flute HSS end mill is needed. The two-flute design provides generous flute valley space, making it well suited for slotting operations and profiling in softer alloys, aluminum, and mild steel. The centercutting geometry allows direct plunge entry without a pre-drilled pilot hole, giving the operator flexibility in toolpath planning. A licensed machinist or CNC operator typically selects this tool when extended reach into a cavity or deep slot requires more length of cut than a standard-series end mill provides.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM7 high speed steel construction for toughness in interrupted and general-purpose cuts\u003c\/li\u003e\n  \u003cli\u003e42-degree helix angle for improved chip flow and reduced cutting pressure\u003c\/li\u003e\n  \u003cli\u003eTwo-flute spiral design optimized for slotting and plunge milling\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eLong-series length of cut at 3 inches suits deep cavity and deep slot applications\u003c\/li\u003e\n  \u003cli\u003eUncoated finish for use with conventional cutting fluids and regrinding without coating concerns\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for milling machines and CNC machining centers that accept a 3\/4-inch straight shank end mill in a standard collet or end mill holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked before inserting or removing the tool from the holder. Secure the shank fully within the collet or end mill holder to the recommended engagement depth to prevent pullout under load. Verify runout at the cutting end after tooling is secured before initiating a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\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, M7 grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches (3.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 42 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: Long Series\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.052 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: E107104802\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51752261779762,"sku":"E107104802","price":97.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fcf6428ff9895ce78c7c566b588046ac.jpg?v=1788927015","url":"https:\/\/voomisupply.com\/products\/hertel-e107104802-square-end-mill-3-4-in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
