The tool produces a 2.09-inch spotface diameter and is sized for a 1-1\/8-inch tube outside diameter. It features 4 straight flutes, a 30-degree seal angle, and a UNJF thread type, making it the correct choice for aerospace and high-pressure fluid system port preparation. The 1-inch shank diameter provides rigid tool holding in standard milling or drill press setups. Licensed machinists and aerospace maintenance technicians are the primary installers of this tool.\u003c\/p\u003e\u003cp\u003eThis reamer is used in applications requiring MS 33649 and AS 5202 compliant port spotfaces, typically found in hydraulic, pneumatic, and fuel system tubing assemblies. The tube dash 18 designation corresponds to the 1-1\/8-inch tube outside diameter. The tool is appropriate for use on workpieces requiring precise seal surface geometry where face angle and spotface concentricity are critical to system integrity.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2.09-inch spotface diameter for MS 33649 and AS 5202 port conformance\u003c\/li\u003e\n\u003cli\u003eReamer pilot type with minimum pilot diameter of 1.425 inches and maximum of 1.5265 inches\u003c\/li\u003e\n\u003cli\u003e4 straight flutes for controlled material removal and surface finish\u003c\/li\u003e\n\u003cli\u003e30-degree seal angle for proper seating surface geometry\u003c\/li\u003e\n\u003cli\u003eUNJF thread type compatibility\u003c\/li\u003e\n\u003cli\u003eBright finish, uncoated for easy inspection and standard machining use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for tube dash 18 applications with a 1-1\/8-inch tube outside diameter per AS 5202 and MS 33649 port standards.
