Constructed from M7 high speed steel with a spiral flute geometry and a 30-degree helix angle, this tool delivers consistent chip evacuation and controlled cutting action in conventional milling setups. The uncoated finish makes it well-suited for applications where re-sharpening is expected. With a 1.75-inch mill diameter, 1.625-inch length of cut, and a 1.25-inch shank diameter, this is a large-format end mill intended for heavy material removal in production or maintenance machining environments. Licensed machinists and tool-and-die tradespeople are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is used in vertical milling machines, knee mills, and CNC machining centers where a standard-length, large-diameter HSS tool is appropriate. Its centercutting design allows plunge entry directly into the workpiece, making it practical for slotting, side milling, and step milling operations. The right-hand cut and right-hand flute configuration follows standard convention for most vertical spindle setups. It is appropriate for use in job shops, maintenance facilities, and production environments where HSS tooling is specified over carbide.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM7 high speed steel construction for toughness and resharpening capability\u003c\/li\u003e\n\u003cli\u003e2-flute spiral geometry with 30-degree helix angle for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without pilot drilling\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for regrinding and use with cutting fluids\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute configuration for standard vertical spindle use\u003c\/li\u003e\n\u003cli\u003eRegular length classification with 1.625-inch length of cut range\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use end mill for standard milling machine and machining center spindles accepting a 1.25-inch straight shank, in applications requiring a large-diameter HSS square end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists following standard toolroom practices. The shank must be secured in a properly sized end mill holder, collet chuck, or Weldon-style holder with adequate clamping torque before spindle engagement. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Confirm runout with a dial indicator after mounting to avoid premature edge wear or workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.125 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\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\u003eWeight\u003c\/strong\u003e: 1.6 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: E1030148\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753804726578,"sku":"E1030148","price":237.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/50e1b1b2d2dd1a63e1a863c6331e2e42.jpg?v=1788940834","url":"https:\/\/voomisupply.com\/products\/hertel-e1030148-square-end-mill-1-3-4-in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
