Scientific Cutting Tools SAEJ1926-06RA Porting Tool Reamer

Product Description

The SCIENTIFIC CUTTING TOOLS SAEJ1926-06RA is a carbide-tipped porting tool reamer designed to machine SAE J1926 and MS16142 straight-thread O-ring ports to precise dimensional tolerances. It produces a 0.990-inch spotface diameter with a 9/16-18 UNF port thread size, making it a purpose-built solution for hydraulic and pneumatic tube fitting ports. The reamer pilot type ensures accurate self-centering during operation, and the AlTiN coating extends tool life in ferrous and high-temperature alloy workpieces. This tool is used by machinists, fluid-power technicians, and maintenance professionals working on hydraulic manifolds, tubing assemblies, and ported components.

This porting tool is suited for applications involving 3/8-inch OD tube connections (Tube Dash 6) in hydraulic and pneumatic systems where SAE J1926 or MS16142 port standards are specified. Typical install scenarios include machining or refinishing O-ring face seal (ORFS) and straight-thread port seats on manifolds, cylinder heads, valve bodies, and hydraulic fittings. The straight shank design allows use in standard drill press, milling machine, or CNC spindle setups. It is appropriate for both production machining and field maintenance rework of ported components in mobile equipment, industrial hydraulics, and aerospace-adjacent fluid systems.

Key Features

• Carbide-tipped construction with AlTiN coating for extended tool life and heat resistance
• 0.990-inch spotface diameter machines the seating face to SAE J1926 and MS16142 standards
• Reamer pilot type with 0.507-inch minimum and 0.619-inch maximum pilot diameter for accurate self-centering
• 3 straight flutes provide clean chip evacuation and consistent surface finish
• 12-degree seal angle matches SAE J1926 straight-thread O-ring port geometry
• 1/2-inch straight shank fits standard drill chucks and collet holders

Compatibility

Designed for use on workpieces requiring SAE J1926 and MS16142 straight-thread O-ring ports with a 3/8-inch tube OD (Tube Dash 6) and a 9/16-18 UNF port thread size.

Installation Notes

This tool is installed and operated by machinists or qualified fluid-power technicians using a drill press, milling machine, or CNC spindle. Ensure the workpiece is fully de-pressurized and secured before machining any ported surface. Use appropriate cutting fluid or coolant compatible with the workpiece material to maintain tool life and surface finish quality. Always verify port dimensions with a calibrated gauge after machining to confirm conformance to the applicable SAE J1926 or MS16142 standard before assembly.
