Scientific Cutting Tools SAEJ1926-06S Porting Tool Carbide

Product Description

The SCIENTIFIC CUTTING TOOLS SAEJ1926-06S is a carbide-tipped porting tool designed to machine SAE J1926 and MS16142 straight-thread O-ring port faces on tube and hydraulic fittings assemblies. It produces a 0.990-inch spotface diameter with a 9/16-18 UNF port thread size, using a plain pilot that ranges from 0.504 to 0.6185 inches in diameter. The 3-flute, straight-flute geometry delivers clean, flat seating surfaces required for leak-free O-ring port connections. With a 3.25-inch overall length and a 0.5-inch straight shank, this tool is typically used in a drill press, milling machine, or hand-held power tool setup by machinists, hydraulic system technicians, and fluid power specialists.

This porting tool is suited for tube workpieces with a 3/8-inch outside diameter, corresponding to Tube Dash Number 6. It is applied in the fabrication and repair of hydraulic manifolds, cylinder ports, and fittings that require a precise spotface and port geometry conforming to SAE J1926 and MS16142 standards. Typical applications include industrial hydraulic systems, mobile equipment hydraulics, and aerospace fluid line assemblies where straight-thread O-ring ports are specified.

Key Features

• Carbide-tipped cutting edges for extended tool life on steel and alloy workpieces
• 0.990-inch spotface diameter machines the seating surface for O-ring port seals
• Plain pilot type with 0.504-inch minimum and 0.6185-inch maximum pilot diameter for positive alignment
• 3-flute straight-flute design promotes chip clearance and surface finish quality
• 12-degree seal angle conforms to SAE J1926 and MS16142 port geometry requirements
• Bright/uncoated finish; 0.5-inch straight shank with 2.0-inch shank length fits standard tool holders

Compatibility

Designed for tube workpieces with 3/8-inch outside diameter (Tube Dash Number 6) requiring 9/16-18 UNF straight-thread O-ring ports per SAE J1926 and MS16142 standards.

Installation Notes

This tool is installed and operated by machinists or hydraulic system technicians using a drill press, mill, or comparable machine tool. Secure the 0.5-inch straight shank firmly in the tool holder and ensure the workpiece is clamped before cutting. Always power down and de-energize any associated hydraulic circuit before performing port machining or repair. Follow shop safety practices and applicable fluid power system service procedures when working on pressurized hydraulic components.
