Scientific Cutting Tools SAEJ1926-03RA Porting Tool Reamer

Product Description

The SCIENTIFIC CUTTING TOOLS SAEJ1926-03RA is a carbide-tipped porting tool and reamer designed for machining SAE J1926 and MS16142 straight-thread O-ring boss ports. It produces a precise 0.760-inch spotface diameter at a 12-degree seal angle, enabling a leak-free seating surface for tube fittings. The tool features a 3-flute straight-flute geometry with an AlTiN coating for extended tool life in ferrous and hard materials. With a 3/8-24 UNF port thread size and compatibility with 3/16-inch tube outside diameter (Dash 3 tubing), it is built for hydraulic and pneumatic port preparation work performed by machinists and fluid-systems technicians.

This porting tool is used in hydraulic system fabrication and repair where SAE J1926 or MS16142 O-ring boss port standards apply. Typical applications include port facing and reaming on manifolds, valve bodies, cylinders, and fittings that accept Dash 3 tube connections. The straight shank and standard series design suit use in CNC machining centers and manual mills alike. It is appropriate for both production environments and field repair setups where precise port geometry is required.

Key Features

• Carbide-tipped construction with AlTiN coating for extended tool life in hard and abrasive workpiece materials
• 0.760-inch spotface diameter with 12-degree seal angle meets SAE J1926 and MS16142 port geometry requirements
• 3/8-24 UNF port thread size for Dash 3 tubing with 3/16-inch tube OD compatibility
• 3-flute straight-flute design provides clean cutting action and chip clearance
• Reamer pilot diameter range of 0.333 to 0.4235 inches ensures accurate centering in existing port bores
• 1/2-inch straight shank fits standard collets and drill chucks for easy setup

Compatibility

Designed for use on workpieces requiring SAE J1926 and MS16142 O-ring boss port preparation with Dash 3 tube connections and 3/16-inch tube outside diameter fittings.

Installation Notes

This tool is intended for use by machinists and hydraulic system technicians in mill or drill press setups. Secure the 1/2-inch straight shank in a properly sized collet or chuck before operation, and verify the pilot diameter is within the 0.333 to 0.4235-inch range of the existing port bore before engaging the tool. Use appropriate cutting fluid or coolant for the workpiece material to protect the cutting edges and coating. Always de-energize and depressurize any hydraulic or pneumatic system before performing port rework.
