Scientific Cutting Tools SAEJ1926-02R Porting Tool Reamer

Product Description

The SCIENTIFIC CUTTING TOOLS SAEJ1926-02R is a carbide-tipped porting tool and reamer designed to machine SAE J1926 and MS16142 straight-thread O-ring ports in tube and fitting assemblies. It produces a 0.682-inch spotface diameter with a 5/16-24 UNF thread port and accepts a 1/8-inch OD tube (Tube Dash 2.000). The 3-flute straight-flute design with a reamer pilot ensures accurate seating surface preparation for leak-free O-ring port connections. Overall length is 3 inches with a 1/2-inch straight shank, making it compatible with standard drill press and CNC setups. Weight is 0.31 pounds.

This tool is used by machinists, hydraulic system fabricators, and fluid power technicians preparing O-ring face seal and straight-thread port connections in tubing assemblies. It is suited for shops working to SAE J1926 and MS16142 standards on hydraulic, pneumatic, and fluid-handling components where precise spotface geometry and port thread prep are required in a single operation. Workpiece compatibility is tubes and fittings requiring a finished seating surface.

Key Features

• Carbide-tipped construction for extended tool life on hardened and alloy workpieces
• 0.682-inch spotface diameter machines the seating face for O-ring port seals in one pass
• Reamer pilot type with minimum pilot diameter of 0.271 inches and maximum pilot diameter of 0.3605 inches for accurate bore alignment
• 3-flute straight-flute geometry provides clean chip evacuation and consistent surface finish
• Meets SAE J1926 and MS16142 standards with a 12-degree seal angle
• Bright uncoated finish; 1/2-inch straight shank with 1.75-inch shank length suits standard toolholders

Compatibility

Designed for use on tube assemblies requiring SAE J1926 and MS16142 straight-thread O-ring port preparation with a 1/8-inch OD tube (Tube Dash 2.000) and a 5/16-24 UNF port thread size.

Installation Notes

This tool is installed and operated by machinists or fluid power technicians using a drill press, milling machine, or CNC machining center. Secure the 1/2-inch straight shank firmly in a collet or chuck before operation, and ensure the workpiece is clamped to prevent movement during spotfacing and reaming. Power down and de-energize all machine spindles before changing or inspecting the tool. Follow applicable shop safety standards and machine manufacturer guidelines for speeds and feeds when working with carbide-tipped tooling.
