Scientific Cutting Tools SAEJ1926-08SA Porting Tool 3/4-16 Unf

Product Description

The SCIENTIFIC CUTTING TOOLS SAEJ1926-08SA is a carbide-tipped porting tool designed to machine SAE straight-thread O-ring boss (ORB) ports to SAEJ1926 and MS16142 standards. It produces a 1.198-inch spotface face and a 3/4-16 UNF port thread seat in a single operation, ensuring a flat, perpendicular seating surface for O-ring fittings. The tool features a plain straight pilot, 3 straight flutes, and an AlTiN coating for extended tool life in ferrous and hard materials. Machinists, hydraulic system fabricators, and fluid power technicians use this tool to prep tube and port connections in hydraulic manifolds, cylinders, and fittings.

This porting tool is applied wherever SAE J1926 or MS16142 O-ring boss port geometry is required. It is suited for use on tubes with a 1/2-inch outside diameter, corresponding to a Dash 8 tube size. Typical applications include hydraulic manifold porting, fluid power component repair, and O-ring port reconditioning in industrial, mobile, and aerospace hydraulic systems. The straight shank mounts in standard drill press, CNC machining center, or manual mill collet holders with a 3/4-inch shank bore.

Key Features

• Spotface diameter of 1.198 inches machines the O-ring seating face to SAEJ1926 and MS16142 specifications
• Carbide-tipped construction with AlTiN coating for wear resistance in steel, cast iron, and hard alloys
• 3 straight flutes for efficient chip evacuation in porting operations
• Plain pilot type with a minimum pilot diameter of 0.685 inches and maximum of 0.8135 inches for accurate centering
• Straight shank at 3/4-inch diameter fits standard collet and chuck holders
• Compatible with 1/2-inch OD tubing (Dash 8) per SAE J1926 port series

Compatibility

Designed for use on workpieces requiring SAEJ1926 and MS16142 straight-thread O-ring boss ports with a 3/4-16 UNF thread size and 1/2-inch tube outside diameter (Tube Dash 8).

Installation Notes

This tool is installed and operated by machinists or hydraulic system technicians using a drill press, milling machine, or CNC machining center. Secure the straight shank in a properly sized collet or chuck before operation, and ensure the workpiece is clamped rigidly to prevent movement during spotfacing. Disconnect and depressurize any hydraulic circuit fully before reworking or reconditioning an existing port. Follow applicable fluid power system standards and shop safety procedures when handling cutting tools and machined components.
