It combines spotfacing and reaming in a single operation, cutting a 0.7420-inch spotface diameter and a 5\/16-24 UNJF port thread seat in one pass. The tool features a 3-flute straight-flute geometry and a bright uncoated carbide-tipped cutting edge for clean, accurate results in tube port machining. Overall length is 3 inches, with a 1\/2-inch straight shank and a 30-degree seal angle conforming to AS5202 and MS33649 specifications. Licensed machinists and aerospace maintenance technicians are the primary installers of this tooling.\u003c\/p\u003e\n\u003cp\u003eThis porting tool is used in applications involving 1\/8-inch OD tubing (Tube Dash Number 2.000) where precision port preparation is required for straight-thread tube fittings. It is suited for both original fabrication and rework of fluid system ports in aerospace, defense, and high-integrity hydraulic or pneumatic assemblies. The minimum pilot diameter is 0.2760 inches and the maximum pilot diameter is 0.3305 inches, providing controlled piloting into existing port bores. Head length is 1.2500 inches and pilot length is 0.5260 inches.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide-tipped cutting edges for extended tool life in hard or abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003e0.7420-inch spotface diameter for accurate AS5202 and MS33649 port seat preparation\u003c\/li\u003e\n  \u003cli\u003e5\/16-24 UNJF port thread size with 30-degree seal angle conforming to aerospace standards\u003c\/li\u003e\n  \u003cli\u003e3-flute straight-flute design for clean chip evacuation and port surface finish\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch straight shank compatible with standard machine spindles and drill press chucks\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish  -  no coating buildup to affect dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/8-inch OD tubing (Tube Dash Number 2.000) port applications conforming to AS5202 and MS33649 standards.

Secure the workpiece firmly and ensure the tool is aligned concentrically with the existing port bore before engaging the pilot. Power down and de-energize all fluid system pressure before performing any port rework on installed assemblies. Follow applicable aerospace maintenance manuals and shop standards for final inspection of port seat geometry and surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpotface Diameter\u003c\/strong\u003e: 0.7420 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePort Thread Size\u003c\/strong\u003e: 5\/16-24 UNJF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: UNJF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter Compatibility\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Dash Number\u003c\/strong\u003e: 2.000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Type\u003c\/strong\u003e: Reamer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Pilot Diameter\u003c\/strong\u003e: 0.2760 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Pilot Diameter\u003c\/strong\u003e: 0.3305 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Length\u003c\/strong\u003e: 0.5260 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\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\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.500 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.7500 inches\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\u003eStandards\u003c\/strong\u003e: AS5202, MS33649\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Standard\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: 0.25 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: AS5202-02R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52052630503730,"sku":"AS5202-02R","price":256.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/781c9cc015206c96e2cf8343c3abca1f.jpg?v=1790035667","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-as5202-02r-porting-tool-reamer","provider":"Voomi Supply","version":"1.0","type":"link"}
