Scientific Cutting Tools SAEJ1926-04SA Porting Tool 7/16-20

Product Description

The SCIENTIFIC CUTTING TOOLS SAEJ1926-04SA is a carbide-tipped porting tool designed to machine SAE J1926 and MS16142 straight-thread O-ring boss (ORB) ports in tube and hydraulic fittings applications. It combines spotfacing, piloting, and port preparation in a single pass. The tool features a 0.838-inch spotface diameter, a plain pilot with a 0.385-inch minimum pilot diameter and 0.489-inch maximum pilot diameter, and a 12-degree seal angle. An AlTiN coating improves heat resistance and tool life in production and maintenance environments. Machinists, hydraulic system technicians, and MRO professionals use this tool when preparing or refacing ORB port faces on tube assemblies.

This porting tool is intended for use on tube workpieces with a 1/4-inch outside diameter (Tube Dash Number 4). The 7/16-20 UNF port thread size and compliance with SAE J1926 and MS16142 standards make it appropriate for hydraulic and pneumatic tube fitting port preparation in both OEM manufacturing and field rework scenarios. The straight flute design and straight shank suit use in drill presses, milling machines, and CNC equipment where controlled depth and repeatable spotface geometry are required.

Key Features

• Carbide-tipped construction with AlTiN coating for extended tool life and heat resistance
• 0.838-inch spotface diameter for accurate ORB port face preparation
• Plain pilot type with 0.385-inch minimum and 0.489-inch maximum pilot diameter
• 12-degree seal angle per SAE J1926 and MS16142 standards
• 3 straight flutes for efficient chip evacuation
• 1/2-inch straight shank with 2.000-inch shank length for secure tool holding

Compatibility

Designed for use on tube workpieces with a 1/4-inch outside diameter (Tube Dash Number 4) requiring a 7/16-20 UNF O-ring boss port. Conforms to SAE J1926 and MS16142 standards.

Installation Notes

This tool is installed in a drill press, milling machine, or CNC spindle using a standard 1/2-inch tool holder or collet. Ensure the workpiece is secured and the system is fully depressurized and de-energized before any port rework on live assemblies. Verify pilot diameter clearance against the existing port bore before engaging the tool to avoid deflection or chatter. Consult applicable hydraulic system service documentation and follow shop safety practices when machining port faces.
