It produces a 1.965-inch spotface diameter with a 30-degree seal angle and 4 straight flutes for clean, accurate seating surfaces. Compatible with 1-inch OD tubing (Tube Dash 16), it features a reamer-style pilot with a minimum pilot diameter of 1.235 inches and a maximum of 1.3385 inches, keeping the tool centered during the cut. Machinists and fluid system technicians use this tool wherever precision boss porting is required per aerospace and industrial fluid power specifications.\u003c\/p\u003e\u003cp\u003eThis porting tool is suited for aerospace, defense, and industrial hydraulic or pneumatic tube assembly applications where O-ring face seal and boss port geometry must conform to MS 33649 and AS 5202 standards. It is used to prepare port faces on manifolds, housings, and fittings that accept Tube Dash 16 connections with 1-inch OD tubing. The bright uncoated finish is appropriate for standard steel and aluminum workpieces typical in these systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.965-inch spotface diameter per AS 5202 and MS 33649 standards\u003c\/li\u003e\n\u003cli\u003e30-degree seal angle for precise O-ring boss port geometry\u003c\/li\u003e\n\u003cli\u003eReamer-style pilot: 1.235 inches minimum to 1.3385 inches maximum pilot diameter\u003c\/li\u003e\n\u003cli\u003e4 straight flutes for controlled cutting action\u003c\/li\u003e\n\u003cli\u003eUNJ thread type compatibility with 1-inch OD Tube Dash 16 connections\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish; overall length 4.37 inches with 2.25-inch shank length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 1-inch OD tubing (Tube Dash 16) and ports conforming to AS 5202 and MS 33649 standards.
