It produces a 1.602-inch spotface diameter with a plain pilot, and its 4-flute straight-flute design delivers clean, accurate seating surfaces required for leak-free UNJF threaded tube connections. With an overall length of 3.75 inches and a 3\/4-inch shank, it mounts in standard milling or drill press setups. This tool is used by aerospace, industrial maintenance, and fluid-systems technicians who need dimensionally verified port faces on tube assemblies.\u003c\/p\u003e\u003cp\u003eThe MS33649-11S is suited for workpieces requiring a Tube Dash 11 port configuration with an 11\/16-inch tube outside diameter. It is commonly used in aerospace maintenance, fluid power systems, and industrial hydraulic manifold work where AS 5202 and MS 33649 port geometry must be held to tight tolerances. The 30-degree seal angle conforms to the standard taper required for proper fitting engagement and reliable sealing. The bright finish shank is compatible with standard collet and chuck toolholding systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpotface diameter of 1.602 inches per MS 33649 and AS 5202 standards\u003c\/li\u003e\n\u003cli\u003ePlain pilot with minimum pilot diameter of 0.923 inches and maximum of 1.0255 inches\u003c\/li\u003e\n\u003cli\u003e4 straight flutes for controlled chip evacuation during spotfacing operations\u003c\/li\u003e\n\u003cli\u003e30-degree seal angle for proper seating geometry on UNJF tube ports\u003c\/li\u003e\n\u003cli\u003e3\/4-inch shank diameter with 2.12-inch shank length fits standard toolholding\u003c\/li\u003e\n\u003cli\u003eBright finish  -  no coating to alter critical dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for Tube Dash 11 port applications with 11\/16-inch tube outside diameter, conforming to AS 5202 and MS 33649 port standards on tube workpieces requiring UNJF thread form and a 30-degree seal angle.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed and operated by machinists, aerospace technicians, or fluid-systems mechanics using a milling machine, drill press, or CNC spindle with an appropriate collet or drill chuck sized for the 3\/4-inch shank. Secure the workpiece firmly before beginning the spotfacing operation and verify pilot engagement before applying feed pressure. Always confirm the port standard and tube dash number against engineering drawings before machining  -  an incorrect spotface diameter will result in a non-conforming port that cannot be reworked to a smaller dimension.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpotface Diameter\u003c\/strong\u003e: 1.602 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter Compatibility\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Dash Number\u003c\/strong\u003e: 11\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: 0.923 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Pilot Diameter\u003c\/strong\u003e: 1.0255 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePilot Length\u003c\/strong\u003e: 0.507 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 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\u003eShank Diameter\u003c\/strong\u003e: 3\/4 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\u003eHead Length\u003c\/strong\u003e: 1.63 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeal Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: UNJF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: AS 5202, MS 33649\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorkpiece Compatibility\u003c\/strong\u003e: Tubes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIdentification Groove\u003c\/strong\u003e: No\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: MS33649-11S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51972171825458,"sku":"MS33649-11S","price":315.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d1e3cc2e2e92d79d0c7f2999d3f86ab_4a77536b-b686-4d9b-b994-4c838631f1f5.jpg?v=1789963644","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-ms33649-11s-porting-tool-tube-dash-11","provider":"Voomi Supply","version":"1.0","type":"link"}
