Scientific Cutting Tools AND10050-5S Porting Tool 4 Flute

Product Description

The SCIENTIFIC CUTTING TOOLS AND10050-5S is a porting tool designed to spotface and prepare tube ports to the AND 10050 standard. It accepts a 5/16-inch tube outside diameter and produces a 0.95-inch spotface diameter with a 30-degree seal angle, ensuring a proper sealing surface for tube fittings in fluid and pneumatic systems. The plain pilot measures a minimum of 0.448 inches in diameter and 0.382 inches in length. With four straight flutes and a bright finish, this tool delivers clean, consistent cuts on tube workpieces. Licensed machinists and aerospace maintenance technicians are the primary users of this tool.

This porting tool is used to machine port seats that conform to AND 10050 specifications, commonly found in aerospace, defense, and high-precision industrial fluid systems. It is suited for applications requiring accurate spotface geometry on tube ports with UNF thread compatibility. The tool is used in both original equipment fabrication and MRO (maintenance, repair, and overhaul) settings where port preparation must meet strict dimensional standards. It is designed for use in machine shop environments and on-equipment drilling and spotfacing operations involving tube dash number 5 fittings.

Compatibility

Designed for use with tube dash number 5 fittings with a 5/16-inch tube outside diameter. Conforms to AND 10050 standard. Intended for UNF thread-type port applications on tube workpieces.

Installation Notes

This tool is installed in a drill press, milling machine, or compatible rotary toolholder using the 1/2-inch shank. Secure the workpiece firmly before operation and confirm the pilot diameter is appropriate for the existing port bore before starting. Power down and de-energize any associated system before performing port machining on installed components. Follow applicable aerospace maintenance manuals and shop safety procedures when performing spotfacing operations.
