Scientific Cutting Tools AND10050-3S Porting Tool

Product Description

The SCIENTIFIC CUTTING TOOLS AND10050-3S is a straight-flute porting tool designed to machine precision spotface seats in hydraulic and pneumatic tube fittings. It produces a 0.805 inch spotface diameter with a 30-degree seal angle, conforming to AND 10050 standards for aerospace and fluid-system porting applications. The plain pilot measures 0.331 inches minimum diameter and 0.344 inches in length, guiding the tool concentrically into the port during the cutting operation. With three flutes and a bright finish, this tool delivers clean, repeatable seat geometry in aluminum, steel, and similar workpiece materials. It is installed and operated by machinists, hydraulic system technicians, and aerospace maintenance professionals.

This porting tool is intended for use on tube fittings with a 3/16 inch outside diameter, corresponding to Tube Dash 3 per AND 10050. It is well suited for aerospace maintenance, defense equipment repair, and industrial hydraulic or pneumatic system assembly where precise port seat geometry is required to achieve leak-free UNF-threaded tube connections. The 1/2 inch shank allows direct chucking in standard drill presses, milling machines, or hand-held pneumatic drilling equipment commonly found in MRO and production environments.

Key Features

• 0.805 inch spotface diameter machines to AND 10050 standard port geometry
• 30-degree seal angle provides consistent seating surface for tube fitting assemblies
• Plain pilot type with 0.331 inch minimum and 0.393 inch maximum pilot diameter for centered entry
• Three straight flutes with bright finish for clean chip evacuation and visual wear inspection
• 1/2 inch shank diameter and 3 inch overall length suit standard machine toolholders
• UNF thread type compatibility aligns with common aerospace and industrial fitting standards

Compatibility

Designed for use with 3/16 inch OD tubes (Tube Dash 3) per AND 10050 standards. Workpiece compatibility is specified for tube-end port applications in hydraulic, pneumatic, and fluid-system assemblies requiring UNF-threaded connections.

Installation Notes

This tool is used by machinists and hydraulic system technicians operating drill presses, milling machines, or similar rotating equipment. Secure the 1/2 inch shank firmly in the toolholder before operation and ensure the workpiece is clamped to prevent movement during spotfacing. De-energize and depressurize any hydraulic or pneumatic system fully before performing port machining or fitting service. Follow applicable shop safety procedures and relevant aerospace or industrial maintenance specifications for port preparation.
