Scientific Cutting Tools AND10050-20S Porting Tool

Product Description

The SCIENTIFIC CUTTING TOOLS AND10050-20S is a porting tool engineered for precision spotfacing and port preparation on hydraulic and pneumatic tube fittings. Built to AND 10050 standards, it features a 2.31-inch spotface diameter and a plain pilot design sized for 1-1/4-inch tube outside diameter (Tube Dash 20). The straight-flute, 4-flute cutting geometry delivers clean, flat seating surfaces required for leak-free tube fitting installations. The tool weighs 2.25 pounds and is finished bright with no coating, giving machinists a clear view of the cutting edges during use.

This porting tool is used in precision machining and mechanical assembly operations where AND 10050-compliant port faces are required on tube fittings, manifolds, and fluid system components. It is suited for shop or field use by aerospace, hydraulic, and industrial maintenance machinists working with straight-thread UN tube connections. The 30-degree seal angle and straight flutes make it appropriate for controlled-depth spotfacing on aluminum, steel, and similar workpiece materials.

Key Features

• Spotface diameter of 2.31 inches for AND 10050-standard port preparation
• Plain pilot type with minimum pilot diameter of 1.537 inches and maximum of 1.6505 inches
• Pilot length of 0.617 inches provides stable tool guidance during spotfacing
• 4 straight flutes for consistent chip evacuation and surface finish
• 30-degree seal angle and UN thread type compatibility for straight-thread tube fitting ports
• 1-inch shank diameter with 2.25-inch shank length for secure toolholder grip
• Bright finish with no coating for unobstructed edge inspection

Compatibility

Designed for use with 1-1/4-inch OD tubes (Tube Dash 20) per AND 10050 standard. Compatible with UN straight-thread tube fitting ports requiring a 2.31-inch spotface and 30-degree seal angle. Workpiece compatibility is listed as tubes.

Installation Notes

This tool is installed and operated by machinists or maintenance technicians using a manual or powered drill press, milling machine, or portable spotfacing unit. Always secure the workpiece fully before engaging the cutter and verify pilot diameter clearance against the existing port bore before use. Do not exceed the tool manufacturer's recommended spindle speeds for the workpiece material. Ensure the work area is clear and appropriate cutting fluid is applied to maintain edge life and surface finish quality.
