It produces a 1.6650-inch spotface diameter with a 1-1\/16-12 UNJ port thread size, making it suitable for precision port preparation to AS5202 and MS33649 standards. The three-flute, straight-flute geometry with a 30-degree seal angle delivers clean, repeatable cuts in metallic workpieces. Licensed HVAC, plumbing, and fluid-system technicians working with high-pressure tubing assemblies rely on tools like this for accurate port finishing on tube dash 12 connections.\u003c\/p\u003e\n\u003cp\u003eThis porting tool is intended for use on 3\/4-inch outside diameter tubes requiring a precisely machined O-ring boss port face. It is applicable in aerospace-derived hydraulic and pneumatic systems, industrial fluid power assemblies, and refrigeration or HVAC tube fitting preparation where AS5202 and MS33649 port standards are specified. The straight shank design allows use in standard drill press or milling machine setups. It is well-suited for shop or field machining of port faces where consistent spotface geometry is critical to achieving a proper O-ring seal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide-tipped cutting edges for extended tool life in metallic tube materials\u003c\/li\u003e\n  \u003cli\u003e1.6650-inch spotface diameter machined to AS5202 and MS33649 port standards\u003c\/li\u003e\n  \u003cli\u003eThree straight flutes with 30-degree seal angle for accurate O-ring boss seat geometry\u003c\/li\u003e\n  \u003cli\u003eReamer-type pilot with 0.9850-inch minimum and 1.0885-inch maximum pilot diameter for self-centering alignment\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch straight shank compatible with standard tool holders and drill chucks\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish for visual wear inspection during service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for port preparation on 3\/4-inch OD tubes to AS5202 and MS33649 standards, tube dash number 12, with a 1-1\/16-12 UNJ port thread size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is operated by a machinist or qualified technician using a drill press, milling machine, or equivalent rotating equipment. Secure the workpiece firmly before engaging the tool to prevent movement during spotfacing. Ensure the machine spindle is aligned perpendicular to the port face to achieve the correct seal angle.
