It combines a spotface and pilot in a single operation, producing a flat seating surface and a properly sized port throat in one pass. The spotface diameter measures 0.838 inches, the port thread size is 7\/16-20 UNF, and the tool accepts a 1\/4-inch tube OD (Tube Dash 4). Three straight flutes and a carbide-tipped cutting head deliver consistent results on steel, aluminum, and other common workpiece materials. This tool is installed by hydraulic system technicians, maintenance machinists, and plumbing fabricators working on fluid-power or high-pressure tubing assemblies.\u003c\/p\u003e\n\u003cp\u003eThis porting tool is suited for tube and fitting work where SAE J1926 or MS16142 port specifications are required. It is used in production and repair environments when cutting or refacing ORB port seats on hydraulic manifolds, cylinder heads, valve bodies, and tubing adapters. The plain pilot style and straight shank allow use in standard drill presses, milling machines, and CNC machining centers. The 12-degree seal angle matches the flat-bottom port geometry specified under the SAE J1926 standard for straight-thread fittings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide-tipped cutting head for extended tool life on steel and aluminum workpieces\u003c\/li\u003e\n  \u003cli\u003e0.838-inch spotface diameter machines the seating surface to SAE J1926 and MS16142 spec in a single operation\u003c\/li\u003e\n  \u003cli\u003eThree straight flutes provide clean chip evacuation and consistent surface finish\u003c\/li\u003e\n  \u003cli\u003ePlain pilot with 0.385-inch minimum and 0.4895-inch maximum diameter guides the tool accurately into the port bore\u003c\/li\u003e\n  \u003cli\u003e12-degree seal angle matches SAE J1926 straight-thread O-ring boss port geometry\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch straight shank fits standard toolholders; bright\/uncoated finish for easy inspection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for machining SAE J1926 and MS16142 straight-thread O-ring boss ports with a 7\/16-20 UNF thread size and 1\/4-inch tube OD (Tube Dash 4) on tubes and fluid-power components.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is intended for use by machinists and hydraulic technicians in machine-shop or field-repair settings. Before porting, depressurize and isolate the hydraulic or fluid circuit completely. Secure the workpiece firmly and ensure the pilot engages the bore squarely before applying feed pressure to avoid chatter or misalignment. Follow the machinery manufacturer feed and speed recommendations for carbide tooling on the workpiece material being machined.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpotface Diameter\u003c\/strong\u003e: 0.838 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter Compatibility\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Dash Number\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePort Thread Size\u003c\/strong\u003e: 7\/16-20 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Angle\u003c\/strong\u003e: 12 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Carbide-Tipped\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Type\u003c\/strong\u003e: Plain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Pilot Diameter\u003c\/strong\u003e: 0.385 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Pilot Diameter\u003c\/strong\u003e: 0.4895 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Length\u003c\/strong\u003e: 0.344 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE J1926, MS16142\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWorkpiece Compatibility\u003c\/strong\u003e: Tubes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.31 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: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SAEJ1926-04S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52101447778610,"sku":"SAEJ1926-04S","price":229.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1045085efe22d03c2116a0a57837dec3.jpg?v=1790069784","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-saej1926-04s-porting-tool","provider":"Voomi Supply","version":"1.0","type":"link"}
