Built to AND 10050 standards, the AND10050-4R features a 0.888-inch spotface diameter, a 30-degree seal angle, and four straight flutes for controlled material removal. With a 1\/2-inch shank diameter and an overall length of 3.12 inches, this tool is sized for use in standard machining setups. It is intended for installation by machinists and maintenance technicians working on tube port preparation in aerospace-adjacent and industrial fluid systems.\u003c\/p\u003e\u003cp\u003eThis reamer is designed for use on tube dash 4 fittings, which correspond to a 1\/4-inch tube outside diameter. It machines workpiece ports to accept AN-style tube connections with a 30-degree seal angle seat. The tool is well suited to maintenance, repair, and overhaul environments where port seat integrity is critical to leak-free tube fitting performance. Typical applications include porting aluminum, steel, or similar machinable materials where a clean, dimensionally accurate spotface is required before tube fitting installation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAND 10050 standard compliance for AN-style tube porting applications\u003c\/li\u003e\n\u003cli\u003e0.888-inch spotface diameter with 30-degree seal angle for precise seat geometry\u003c\/li\u003e\n\u003cli\u003eFour straight flutes for smooth, controlled cutting action\u003c\/li\u003e\n\u003cli\u003eMinimum pilot diameter of 0.386 inches and maximum pilot diameter of 0.4565 inches for accurate bore alignment\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish  -  no coating buildup affecting dimensional tolerances\u003c\/li\u003e\n\u003cli\u003e1\/2-inch shank diameter compatible with standard drill press and milling machine chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with tube dash 4 fittings with a 1\/4-inch tube outside diameter, machined to AND 10050 standard port geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed and operated by machinists or qualified maintenance technicians using a drill press, milling machine, or appropriate rotary spindle setup. Secure the workpiece firmly before operation and verify spindle speed is appropriate for the workpiece material. Ensure the pilot is fully seated in the existing bore before engaging the spotface cutter to prevent seat runout. Always follow applicable shop safety procedures and system-specific fluid line service guidelines when working on pressurized tube fitting ports.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpotface Diameter\u003c\/strong\u003e: 0.888 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter Compatibility\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Dash Number\u003c\/strong\u003e: 4\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: 0.386 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Pilot Diameter\u003c\/strong\u003e: 0.4565 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePilot Length\u003c\/strong\u003e: 0.527 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\u003eOverall Length\u003c\/strong\u003e: 3.12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.24 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.88 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePilot Type\u003c\/strong\u003e: Reamer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorkpiece Compatibility\u003c\/strong\u003e: Tubes\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: AND 10050\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: AND10050-4R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51995570307378,"sku":"AND10050-4R","price":269.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/20010cbdb1d19f0b5ba9178489de5668.jpg?v=1789992775","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-and10050-4r-porting-tool-reamer","provider":"Voomi Supply","version":"1.0","type":"link"}
