Scientific Cutting Tools SAEJ1926-20R Porting Tool Reamer

Product Description

The SCIENTIFIC CUTTING TOOLS SAEJ1926-20R is a carbide-tipped porting tool designed to machine SAE J1926 and MS16142 straight-thread O-ring boss (ORB) ports in hydraulic and fluid-power tube assemblies. It combines a spotface cutter and a reamer-style pilot into a single tool, allowing the technician to finish the port face and pilot bore in one operation. The spotface diameter is 2.29 inches, the port thread size is 1-5/8-12 UN, and the tool accepts a 1-1/4 inch tube outside diameter. Three straight flutes and a bright, uncoated carbide-tipped cutting geometry deliver clean, burr-free seating surfaces for reliable O-ring sealing.

This porting tool is used in the fabrication and repair of hydraulic manifolds, fluid-power blocks, and tube-end port faces where SAE J1926 or MS16142 straight-thread ORB port standards are specified. Typical applications include industrial hydraulic systems, mobile equipment hydraulic lines, and aerospace-adjacent fluid systems that require precision port geometry for leak-free O-ring boss connections. The tool is suited for machining operations performed by hydraulic system technicians, tool-and-die machinists, and fluid-power maintenance professionals working on tube Dash 20 port configurations.

Key Features

• Carbide-tipped cutting edges for extended tool life in steel and ductile iron workpieces
• Reamer-style pilot with 1.542 inches minimum and 1.7155 inches maximum pilot diameter for precise bore alignment
• 2.29 inches spotface diameter finishes the port seating face in a single pass
• 3 straight flutes for efficient chip evacuation and clean surface finish
• 15-degree seal angle geometry conforms to SAE J1926 and MS16142 port standards
• 1 inch straight shank provides rigid setup in standard tool holders or drill press chucks
• Bright, uncoated finish for easy visual inspection of cutting edge condition

Compatibility

Designed for machining SAE J1926 and MS16142 straight-thread O-ring boss ports in tube and manifold workpieces with a 1-1/4 inch tube outside diameter and Tube Dash Number 20.000. Port thread size is 1-5/8-12 UN.

Installation Notes

This tool is operated by machinists or hydraulic system technicians using a drill press, milling machine, or CNC machining center with the workpiece securely fixtured. Ensure the workpiece is fully de-pressurized and drained before any port machining on in-service components. Use appropriate cutting fluid to maintain edge life and surface finish quality. Follow SAE J1926 or MS16142 specifications for final port geometry verification before assembly.
