It produces a 1.24-inch spotface diameter with a 30-degree seal angle, preparing the mating surface for leak-free AS 5202 and MS 33649 standard connections. The plain pilot design accepts 1\/2-inch tube OD (Tube Dash 8) workpieces. With four straight flutes and a bright uncoated finish, this tool delivers clean, consistent material removal on the spotface seat. Machinists and fluid-system technicians use this tool where precise face geometry is required to meet aerospace and hydraulic plumbing standards.\u003c\/p\u003e\u003cp\u003eThis porting tool is suited for use on tube and fitting assemblies requiring AS 5202 or MS 33649 port preparation. Typical applications include aerospace, industrial hydraulic, and pneumatic plumbing systems where UNJF-threaded ports must be spotfaced to a controlled geometry before fitting installation. The tool accommodates workpieces with 1\/2-inch tube OD and is compatible with tube dash number 8 configurations. Its 3\/4-inch shank fits standard milling machine or drill press collet and chuck setups used in production and maintenance environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.24-inch spotface diameter machines the bearing face to AS 5202 and MS 33649 dimensional standards\u003c\/li\u003e\n\u003cli\u003e30-degree seal angle ensures correct mating geometry for leak-free tube fitting connections\u003c\/li\u003e\n\u003cli\u003ePlain pilot type with 0.692-inch minimum and 0.7715-inch maximum pilot diameter for consistent centering\u003c\/li\u003e\n\u003cli\u003eFour straight flutes provide clean cutting action and efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eUNJF thread type compatibility aligns with aerospace and hydraulic port specifications\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for general-purpose spotfacing on a range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on tube workpieces requiring Tube Dash 8 (1\/2-inch tube OD) port preparation in accordance with AS 5202 and MS 33649 standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed and operated by machinists or fluid-system technicians using a drill press, milling machine, or similar rotating spindle equipment. Secure the 3\/4-inch shank firmly in a collet or chuck before operation and ensure the workpiece is clamped to prevent movement. Always de-energize and de-pressurize any hydraulic or pneumatic system before performing port machining work. Follow applicable aerospace or industrial safety and quality standards for port preparation procedures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpotface Diameter\u003c\/strong\u003e: 1.24 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter Compatibility\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Dash Number\u003c\/strong\u003e: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeal Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Pilot Diameter\u003c\/strong\u003e: 0.692 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Pilot Diameter\u003c\/strong\u003e: 0.7715 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePilot Length\u003c\/strong\u003e: 0.458 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.57 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.45 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eThread Type\u003c\/strong\u003e: UNJF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: AS 5202, MS 33649\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: 0.75 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: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MS33649-8S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52083888423218,"sku":"MS33649-8S","price":267.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1dc5b3a4aa818870ae6f27e377ca55a2.jpg?v=1790057855","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-ms33649-8s-porting-tool-tube-dash-8","provider":"Voomi Supply","version":"1.0","type":"link"}
