Scientific Cutting Tools MS33649-9R Porting Tool Reamer

Product Description

The SCIENTIFIC CUTTING TOOLS MS33649-9R is a precision porting tool designed to machine and finish port faces on tube fittings to AS 5202 and MS 33649 standards. It combines a spotface cutter and reamer pilot in a single tool body, producing a flat, square seating surface for tube end fittings used in high-pressure fluid and hydraulic systems. The spotface diameter measures 1.3 inches, the pilot type is a reamer with a minimum pilot diameter of 0.758 inches and a maximum of 0.8345 inches, and the tool is configured for a 9/16-inch tube outside diameter (Tube Dash 9). Installation is performed by licensed machinists and precision fabricators working on aerospace, hydraulic, and industrial fluid line assemblies.

This porting tool is suited for applications requiring conformance to AS 5202 and MS 33649 port standards. It is used when preparing tube fitting ports in metal workpieces, particularly tube assemblies that use UNJ thread forms and 30-degree seal angles. Typical use cases include hydraulic manifold porting, aerospace tube end preparation, and industrial fluid system fabrication where precise spotface geometry is required to ensure leak-free sealing at tube connections.

Key Features

• Spotface diameter of 1.3 inches conforms to AS 5202 and MS 33649 port standards
• Reamer pilot type ensures accurate centering with minimum pilot diameter of 0.758 inches and maximum of 0.8345 inches
• 4 straight flutes provide controlled cutting action and clean chip evacuation
• 30-degree seal angle machined to match standard tube fitting seat geometry
• UNJ thread type compatibility for high-pressure fluid line applications
• Bright finish on tool body; 3/4-inch shank diameter fits standard toolholders

Compatibility

Designed for use on tube workpieces conforming to AS 5202 and MS 33649 port standards, specifically for 9/16-inch tube outside diameter (Tube Dash 9) applications with UNJ thread forms.

Installation Notes

This tool is installed and operated by machinists or qualified fabricators using standard milling machines or drill presses with appropriate toolholding for a 3/4-inch shank. Secure the workpiece firmly before operation to prevent movement during spotfacing. Follow applicable aerospace or industrial fabrication standards for surface finish and dimensional inspection after porting. Do not exceed the tool's rated cutting parameters for the workpiece material.
