It produces a 0.742-inch spotface diameter with a 30-degree seal angle, conforming to AS 5202 and MS 33649 standards. The reamer pilot type ensures accurate alignment during the cutting operation. With a 3-inch overall length and 3 straight flutes, this tool delivers clean, repeatable results in ferrous and non-ferrous workpiece materials. It is typically installed by machinists, aerospace maintenance technicians, and fluid-systems mechanics working on tube-fitting port preparations.\u003c\/p\u003e\u003cp\u003eThis porting tool is intended for tube dash number 2 applications with a 1\/8-inch tube outside diameter. It is used when preparing ports to accept MS 33649 and AS 5202 standard fittings in aerospace, defense, and industrial fluid-line systems. The 1\/2-inch straight shank mounts in standard drill presses, milling machines, or hand-held power tools where port geometry must meet tight angular and dimensional tolerances. The bright, uncoated finish suits general-purpose porting operations across a range of base materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.742-inch spotface diameter conforms to AS 5202 and MS 33649 standards\u003c\/li\u003e\n\u003cli\u003e30-degree seal angle for proper fitting seat geometry\u003c\/li\u003e\n\u003cli\u003eReamer pilot type with 0.276-inch minimum and 0.331-inch maximum pilot diameter for accurate bore alignment\u003c\/li\u003e\n\u003cli\u003e3 straight flutes over a 1.25-inch head length for clean material removal\u003c\/li\u003e\n\u003cli\u003e1\/2-inch straight shank with 1.75-inch shank length for secure tool holding\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for general-purpose tube-port machining\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with tube dash number 2 fittings having a 1\/8-inch outside diameter, and conforming to AS 5202 and MS 33649 port standards on tube workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is used by machinists and fluid-systems technicians; depressurize and lock out all hydraulic or pneumatic lines before performing any port machining in live systems.
