Built to Series JH780 specifications, it features a 1.83 mm diameter, a 23.5 mm length of cut, and a 1 mm corner radius across four right-hand spiral flutes. The HXT coating provides thermal resistance and wear protection suited to cutting high-temperature alloys. With an 8 mm straight-cylindrical shank and a 63 mm overall length, this single-end tool is configured for short-reach finishing and semi-finishing passes where dimensional accuracy is critical.\u003c\/p\u003e\u003cp\u003eThis end mill is engineered for machining high-temperature alloys, identified by workpiece material code S, which includes nickel-based superalloys and similar difficult-to-cut materials. Its medium helix style balances chip evacuation with cutting stability at the small diameters involved. The tool is suited for CNC machining centers in aerospace, power generation, and precision component manufacturing environments where tight tolerances and surface finish requirements are standard.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.83 mm mill diameter with a mill diameter tolerance of -0.04 to -0.04 mm for consistent sizing\u003c\/li\u003e\n\u003cli\u003e1 mm corner radius reduces stress concentration and extends tool life at the cutting edge\u003c\/li\u003e\n\u003cli\u003eHXT coating enhances heat resistance and abrasion protection for high-temperature alloy cutting\u003c\/li\u003e\n\u003cli\u003eFour right-hand spiral flutes with medium helix promote chip flow and cutting stability\u003c\/li\u003e\n\u003cli\u003e8 mm shank diameter with h5 tolerance ensures secure, repeatable toolholder seating\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction delivers rigidity at small diameters where deflection control matters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-application solid carbide end mill within the SECO JH780 series, suitable for standard straight-bore toolholders accepting an 8 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the toolholder manufacturer's clamping torque and runout specifications. Confirm shank seating depth and verify radial runout at the spindle before starting a cut. Coolant-through is not supported on this tool, so external coolant or air blast should be directed at the cutting zone. Always inspect the cutting edge under magnification before use and after each job when working with high-temperature alloys.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.83 mm (0.0719 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 23.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 63 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.04 to -0.04 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: HXT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Ballnose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: High Temperature Alloy (Code S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: JH780\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.41 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: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 03127386\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558389252402,"sku":"03127386","price":256.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d8e87a3cf6fcc46651f2a3a6fcce272.jpg?v=1786410897","url":"https:\/\/voomisupply.com\/products\/seco-03127386-corner-radius-end-mill-1-83mm-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
