Scientific Cutting Tools SAEJ1926-03R Porting Tool Reamer

Product Description

The SCIENTIFIC CUTTING TOOLS SAEJ1926-03R is a carbide-tipped porting tool and reamer designed to machine SAE J1926 and MS16142 straight-thread O-ring ports in hydraulic and fluid-system components. It combines spotfacing and piloted reaming in a single pass, producing a 0.760-inch spotface diameter with a 3/8-24 UNF port thread size and a 12-degree seal angle. The straight-flute, 3-flute design runs on a 1/2-inch straight shank and covers a minimum pilot diameter of 0.333 inches up to a maximum of 0.4235 inches. Machinists, hydraulic system technicians, and fluid-power mechanics use this tool to recondition or prepare port faces on manifolds, cylinders, and fittings.

This porting tool is intended for use on tube and fitting assemblies requiring a 3/16-inch tube outside diameter with a Tube Dash Number of 3. It is well-suited for production and maintenance work on hydraulic manifolds, pneumatic blocks, and fluid-power components where precise port geometry is required for O-ring face seal integrity. The bright, uncoated carbide-tipped construction handles both ferrous and non-ferrous workpiece materials without the need for a coating.

Key Features

• Carbide-tipped construction for durability across ferrous and non-ferrous materials
• 0.760-inch spotface diameter with 12-degree seal angle for SAE J1926 and MS16142 port compliance
• 3-flute, straight-flute geometry provides clean, stable cutting action
• Integrated reamer pilot guides the tool on-center for consistent port geometry
• 1/2-inch straight shank compatible with standard drill press, milling machine, and hand-held power tool setups
• Single-tool operation combines spotfacing and piloting to reduce setup steps

Compatibility

Designed for machining SAE J1926 and MS16142 straight-thread O-ring ports with a 3/8-24 UNF thread size and a 3/16-inch tube outside diameter (Tube Dash Number 3). Workpiece compatibility is specified for tubes and tube-end fittings.

Installation Notes

This tool is installed and operated by machinists or hydraulic technicians using a drill press, milling machine, or torque-controlled hand-held power tool. Depressurize and isolate any hydraulic or pneumatic circuit before porting or reworking a fitting or manifold. Secure the workpiece firmly to prevent movement during the spotfacing pass, and use an appropriate cutting fluid for the workpiece material. Verify final port geometry against SAE J1926 or MS16142 specifications before installing O-ring seals and reassembling the circuit.
